The seminar concludes with a review of the OSHA regulations applicable to emergency responses and emergency responders.
CH-112 Alternative Fuels for Electrical Power Generation
Global warming concerns versus the need for more power to accommodate the requirements of a growing worldwide population have resulted in debates to identify technologies that can meet the demand while simultaneously reducing greenhouse gases. Coal, the most commonly used source of energy to generate base-load electrical power, is a primary source of the greenhouse gases that contribute to global warming. Research is underway to gasify and liquefy coal in an effort to reduce its harmful emissions when used for power generation and to create an alternate source of diesel fuel. Nuclear energy has the potential to supply a major portion of the world’s energy requirements but it has problems of its own that makes it less than ideal. Bio-fuel, i.e. ethanol from corn, is being touted as the means to significantly reduce our dependence on foreign oil as well as using methane from landfill areas. However, the farmland required to grow the feedstock reduces the amount of land required to grow important food crops, i.e. soybeans, etc. used by both man and animal. The basics of these technologies, their economics, and the political arguments for and against each of these technologies will be presented and contrasted.

CH-119 Fundamentals, Technologies, & Safeguards of Nuclear Energy (Part #1)
There are 436 nuclear power plants worldwide generating approximately one sixth of the electrical power consumed. Approximately one quarter of all the nuclear power plants is located in the United States with one quarter of all US plants located in the Northeast. The existing plants are aging and will require renovation.
The rates of fossil fuel consumption and carbon dioxide emission rise every year, seriously affecting the Earth’s climate. The current difficulties with fossil fuel supply and its rising price along with nuclear powers half century of commercial operation have engendered renewed interest in nuclear power as a potential source of clean energy.

CH-123 Synthetic Fuels: Fisher-Tropsch Conversion Process (Part #1)
Fischer-Tropsch Synthesis (FTS) is the key step in the manufacture of liquid hydrocarbon fuels from a variety of carbon based sources, including gas, coal, shale, biomass, and waste. The purpose of FTS is to produce a synthetic oil substitute, for use as lubricants or synthetic automotive, truck and aircraft fuel. FTS involves a catalyzed chemical reaction in which synthesis gas (carbon monoxide and hydrogen) is converted into liquid hydrocarbons of various forms. Synthesis gas is easily manufactured via steam reforming of hydrocarbons or (more likely) partial oxidation or POX. The combination of POX (gasification) and FTS is considered to be a key technology in the quest for the United States energy independence. In this seminar, a snapshot of the current energy utilization picture in the United states will be presented as well as the opportunity for FTS. The chemistry and processing of the FTS process will be reviewed.
CH-124 Synthetic Fuels: Fisher-Tropsch Conversion Process (Part # 2)
The original Fischer Tropsch Synthesis (FTS) process was invented by Franz Fischer and Hans Tropsch in the 1920s with the sole purpose of producing liquid fuels. The political goal was to provide energy independence for Germany which was rich in coal but had little petroleum. Nowadays, the FTS process is established technology and has been applied on a large scale in some countries. However, the popularity of the FTS is limited due to the low hydrogen content of some of the incoming fuels. This results in the need to reject carbon dioxide from the process, thus reducing yield and causing environmental concerns. Additionally, the low yield restricts the economic viability of FTS to situations in which alternatives for liquid fuels, such as petroleum are very costly. In this seminar the production and import of hydrogen gas into the FTS process will be presented. The required processing for the manufacture of low cost hydrogen will be discussed and the process integration with FTS process will be presented.
CH 125 The Engineering and Economics of Bio-Fuel
The production need to free the US from our dependence on foreign oil has motivated the rapid development of the bio-fuels industry. Further, the use of bio fuels has been proposed as a substitute for fossil fuels as a way to combat global warming. Finally, bio fuels derived from vegetation are considered a renewable resource.
Photosynthesis, a complex biological enzymatic process, traps solar energy into the carbon-carbon bonds of organic carbohydrate polymers, and fat molecules. The bio fuel industry has developed chemical and biochemical processes to create smaller organic molecules, both liquid and gaseous, from these plant polymers suitable as fuels for automobiles, trucks, etc. The two most common liquid molecules are ethanol and bio-diesel; the most common gaseous molecule is methane.
In this presentation, we will introduce the biochemical processes that form the organic polymers; describe the prominent productions schemes used to create bio-fuels, and evaluate the energy balance of the processes. We will examine the arguments for an against bio-fuel production e.g. "water and plant consumption for fuel" versus "food"; and consider the economics and effects of bio-fuel production on our climate.

Select examples that will discussed to give the attendee an appreciation of how to initiate the design such a system.
CH-134 Contemporary Arguments on Nuclear Power (Pt. #2)
As of May 2011, 12 incidents involving nuclear fission reactors have been reported, four in the United States, three in Japan, two in France, and one each in Scotland, East Germany and Ukraine. These incidents have resulted in the release of varying amounts of radioactivity into the atmosphere and surrounding areas from damage to the reactor cores. The most recent incident occurred at the Daiichi plant in Fukushima, Japan as a result of a magnitude 9.0 Richter scale earthquake and the associated tsunami. This incident has renewed concern about nuclear fission reactor facilities as safe base-load electrical energy generation stations. This presentation will review the 12 incidents in chronological order covering their probable causes, remediation, radiation released and health effects. The lecture will include the scale used to rate the “seriousness” of nuclear incidents and how these incidents have influenced safety practices at current and future nuclear reactor facilities.
CH-135 Hydraulic Fracking; Technology, Economic, Health and Safety Issues (Part #1)
Fracking is the colloquial name for the process of hydraulic fracturing to recover deeply held natural gas and oil. In fracking a high pressure fluid with suspended solid particles, known as proppants is injected into deep well-holes. Cracks are created in sedimentary rock and the proppant (usually sand) holds open the crack, releasing trapped oil and gas. Geological assessments indicate that there are enormous quantities of gas available for recovery via fracking in the eastern United States in the Marcellus Shale formation. In part 1 of this two part seminar a snapshot of the current natural gas mining procedures will be presented.
CH-136 Hydraulic Fracking; Technology, Economic, Health and Safety Issues (Part #2)
Environmental, Health, and Safety (EHS) concerns have developed over the process of fracking, with some of the biggest issues being the uncontrolled release of natural gas as well as the contamination of drinking water with natural and synthetic toxins including reportedly radioactive material. In this two part seminar, current and historic mining processes will be presented along with utilization and transportation options. In part 2 of this two part seminar the economic incentive as well as the key societal issues on both sides of the debate over fracking will be discussed.
CH-137 Environmental Remediation Awareness for Building Design Professionals
This four hour lecture will briefly touch on common environmental issues and regulations that could come up during the operation of existing buildings or the design of new buildings. The course will include a brief discussion of the major sources of environmental pollutants (air pollution, water pollution and hazardous or chemical waste management). We will then discuss federal and local regulations that have been put in place to control these sources and how they could pertain to buildings. The origins of regulations and how they flow from the federal to local level will also be discussed. Common environmental issues that should be addressed during design such as Wetland permits, dealing with “Universal Waste”, Storm water Drainage, air emissions… will be addresses. The instructor will use environmental investigations and/or building designs that he has been involved in as case studies during the course.
CH-138 Hazardous Material and Confined Space Awareness for Building Design
The first half of this seminar will provide guidance on the proper management of potentially hazardous chemicals in buildings and structures. We will be discussing various chemical hazards, the forms these hazards are in and their routes of entry into the body. Regulations and building codes relating to the storage, use and disposal of used chemicals will also be reviewed. The instructor has had extensive experience in addressing work place chemical management programs and will discuss the same during the seminar. After reviewing hazardous chemicals we will discuss the management and recognition of “confined spaces” in buildings and structures. Topics include local and federal regulations, compliance with building codes, and definitions used in the industry. During the course we will go over the health and safety hazards associated with such spaces. We will review processes used to classify confined spaces and how to manage an entry permit procedure for such spaces. The instructors experience in dealing with confined spaces while working for the United States Navy on nuclear submarine repairs will be used as case histories during the course.
CH-139 OSHA Regulations for Hazmat, Demolition and Construction (Part # 1)

CH141 will focus on what, if anything, we can or should do to improve our chances for survival. We will introduce concepts of adaption to help our world cope with current climate effects while simultaneously developing strategies to mitigate the perceived factors that are accelerating climate change.
• The important concerns we face today are how do we anticipate and then accommodate the expanding world population’s need for food, shelter, health needs, and energy requirements in the face of the climatic turmoil we are experiencing.
• Humans are the current dominate inhabitants of earth but unlike other dominate species that became extinct from climate change humans possess the intellectual capacity and engineering capability to cope with the current climatic challenges and perhaps influence the outcome and the survival of our species.
CH-142 Shale Gas Conversion Part I: Methane Processing & Economics
With the discovery of vast quantities of natural gas available in various shale formations in Pennsylvania, New York and several adjoining states comes the opportunity to convert this gas, traditionally used for fuel, into more value added products. The methane portion can be processed into intermediates such as ethylene via oxidative coupling or converted into Liquefied Natural Gas (LNG) for shipping. In this seminar the processing requirements and performance of a variety of technologies starting with methane will be presented.
CH-143 Shale Gas Conversion Part II: NGL Processing & Economics
With the discovery of vast quantities of natural gas available in various shale formations in Pennsylvania, New York and several adjoining states comes the opportunity to convert this gas, traditionally used for fuel, into more value added products. Substantial quantities of ethane and propane (E/P mixes) are associated with the methane in shale gas. This ethane/propane fraction, traditionally know as Natural Gas Liquids or NGLs can be converted into ethylene via conventional steam pyrolysis or oxidative dehydrogenation. In this seminar the processing requirements of a variety of technologies starting with E/P mixes will be presented.
CH-144 Alternative Fuels for Electrical Power Generation (Pt.2)
Global Warming / Climate Change - concerns versus the need for more electrical power to accommodate the requirements of a growing worldwide population have necessitated the development of alternative power generating technologies to meet the demand while simultaneously reducing greenhouse gas [GHG] emissions. Combustion of coal, the most commonly used world-wide source of energy to generate base-load electrical power, is also the primary source of GHG gases that contribute to the anthropogenic sources of global warming. Research is underway to develop alternative fuel technologies for production of electricity and transportation. We will investigate the basics of liquid and gaseous fuels that hold the potential for electrical power generation as an alternative to combustion of coal, oil, mined natural gas and alternative modes of extracting energy from them.
CH-145 The Influence of Air & Water Pollution on Climate Change (Pt.1)
Is our planet undergoing “Global Warming”? Is the rate of climate change increasing? Is human activity to blame? These are questions many people around the world are asking in light of warmer winters, hotter summers, and severe storms, draught, expanding deserts and melting polar ice caps. However we may not be able to answer these questions with high degree of certainty because climate changes, unlike weather patterns, occur over periods of thousands of years and not within the time span of a few generations.
We must acknowledge that climate change is the norm and not the exception when viewed from astronomical timelines. Earth’s climate has cycled from warm to cold to warm several times and will, in all likelihood, continue this pattern. This lecture will present the latest scientific evidence that has been accumulated and the mathematical modeling efforts used to predict climate change in the future from various scenarios. The information used in the presentation comes from the most rent IPCC AR5 report published in Oct. 2014; scientific studies published in peer-reviewed high impact factor journals, e.g. Nature, Science; and commentary from newspapers, e.g. NY Times. Every effort is made to present an unbiased and balanced presentation of the scientific/engineering facts published on the complex subject or climate change..
CH-146 The Influence of Air & Water Pollution on Climate Change (Pt.2)
Water and air pollution affect the rate of and are affected by climate change. “Pollutants” are released into the earth’s atmospheric and oceanic systems and influence the systems’ chemical constituents & physical processes as well as with the biological organisms that inhabit those systems. Part 1 of this two-part lecture series introduced and summarized the observations associated with pollutants that are suspected to influence climate change.
This lecture will present the latest scientific findings from investigations to elucidate the underlying mechanisms of how pollutant iterations with atmospheric and oceanic systems directly influence climate. This course will introduce the student to the underlying geo-chemical and geo-physical phenomena associated with pollutant interactions with atmospheric and oceanic chemical constituents. Simple mathematical models of earth’s climate dynamics will be introduced to help understand the influence and location of pollution emissions on the distribution of pollutants between land, air and water spaces and the effects they have on global thermodynamics. The mathematical modeling material will include web–based simulation software used to study climate parameters as a function of pollutant concentration. The lecture materials are taken from scientific studies published in peer-reviewed high impact factor journals, e.g. Nature, Science; published textbooks on the subject and web resources.
CH-147 Chemical Reactor Design (Pt. 1)
In reaction engineering the conversion of certain molecules into different molecules (chemical systems) or the conversion of molecules into energy (nuclear systems) are studied. The key unit operation in reaction is the reactor which must be designed to process the chemicals as well as manage the heat effects. In the first part of the two part seminar, the basics of the chemistry surrounding the chemical or nuclear change are presented along with the associated heat effects. The concept of stoichiometry which is the instructions for the reactor are presented. The difference between types of reactors and the choices involved in the processing of the stoichiometry are also presented.

In the second part of the two part seminar, the details of the different types of reactors are described and examples of the corresponding design and operation are presented. The fundamental mass transfer equation will be used to describe the reactor and inform the design. Reactors presented will involve nuclear and chemical change from a variety of industries and government agencies, including NASA. In industry chemical reactors often account for 25-50% of the total capital cost of the plant and the energy cost or energy recovery are usually a significant portion of the cost of production. A roadmap for the selection of an appropriate reactor will be presented.
CH-149 The Engineering of Genetically Modified Foods & Water Purification #1
Climate change, the increase of global population and the reduction of available land and potable fresh water supplies are causing a re-thinking of contemporary techniques used for the production and distribution of mankind’s plant and animal food staples. The concern is that these techniques will be unable to feed the world’s population in the 21st century. Until recently, plant and animal “Mendelian” husbandry techniques were applied to develop more robust staple organisms that make up our diet. With advances in genetic engineering these organisms can now be modified in ways that are not possible with traditional techniques. Specifically we now have the ability to incorporate genes into organisms from other species to create chimeras that grow faster; are more resistant to diseases and insect pests; tolerate herbicides; and are able to grow in brackish water. These new species are referred to as “genetically modified organisms” or GMOs. These GMOs require new production techniques to bring them to market and prevent their interacting with native species. This lecture will introduce the climate and population factors that are causing concern and consider the world’s projected food requirements. Then we will examine the contemporary agricultural, hydroponic, aquaculture and animal engineering techniques used to grow our food, and introduce the concepts of genetic engineering techniques, i.e. CRISPR, used to create new chimeric organisms and their special requirements. We will next introduce the recent unanticipated problems discovered with the safety of GMO consumption and conclude with the ethical considerations associated with GMO versus current staple plant and animals in the context of feeding the world.
CH-150 The Engineering of Genetically Modified Foods & Water Purification #2
Climate change, the increase of global population, the reduction of available land and potable fresh water supplies is causing a re-thinking of techniques for the production and distribution of the plant and animal food staples to provide adequate and sustainable quantities for the 21st century. Until recently, fresh water was in plentiful supplies with local lakes, rivers and reservoirs fed from underground aquifers; mountain’s glacier run-off and snow melt and plentiful rains. However irresponsible water usage practices; competition for water sources by hydraulic fracturing processes; an increase in severe droughts and changing weather patterns has resulted in a serious loss of fresh potable water. This presentation will examine the world population needs, usage practice and the present day challenges to our water supply, and introduce the technologies being developed and incorporated to provide potable water for the 21st century.
CH-151 Carbon Nano-tube Filtration Techniques for Potable Water (Pt.1)
Scientists agree that clean water is vital to sustain life. With the pressures of the modern world and increasing population, many people (closing in on 2 billion) are without a available source of clean water. Technology to make water of a satisfactory purity as well as in adequate supply and available at a given location are the key components of potable water. Improving access to safe drinking-water can result in a reduction in water borne illnesses and improved health. According to the World Health Organization (WHO), very effort should be made to achieve a drinking-water quality as safe as practicable. Drinking water that is safe does not represent any significant risk to health over a lifetime of consumption, including different sensitivities that may occur between life stages. In the first part of the seminar, the problem will be scoped and options for remediation will be presented.
CH-152 Carbon Nano-tube Filtration Techniques for Potable Water (Pt.2)
In Part 2 a brief scoping review of the world-wide situation regarding clean water is presented. The situation of those at greatest risk of waterborne disease is discussed along with the technology to produce safe drinking-water for all usual domestic purposes, including personal hygiene. The WHO has published guidelines for potable water which are also applicable to packaged water and ice intended for human consumption. However, the WHO states that their guidelines may not be suitable for the protection of aquatic life or for some industries. A detailed analytical review of technology to provide potable water in multiple societal and industrial contexts is discussed as well as the technology required for water of higher quality for some special purposes. Those who are severely immunocompromised may need to take additional steps, due to their susceptibility to organisms that would not normally be of concern through drinking-water. The seminar will conclude with a projection about future water supplies and quality including a discussion of the “limits to growth”.
CH-153 Advanced Processing of Natural Gas for the Petrochemical Industry #1
The world-wide petrochemical industry has greater than $1 trillion yearly market value of products ranging from intermediates to finished products. These appear throughout our everyday existence. About 25% of the petrochemicals are supplied by the US, which is the dominant world-wide producer. Petrochemicals are produced by steam pyrolysis, an energy and capital intensive process. Typical grass root plant costs are about $4 billion for a world scale plant and these facilities contribute greatly to the carbon footprint. Nearly 5 quads of energy are consumed by this industry every year. In part 1 of the seminar, the industry will be described and the leveraging parts of the technology identified. Key areas for technology improvement will be discussed.
CH-154 Advanced Processing of Natural Gas for the Petrochemical Industry #2
This seminar is a continuation of the previous effort in which the industry was laid out in detail and the weak points identified. With the abundance of low cost natural gas, the US dominance in petrochemical processing is even more secure. One of the by-products of the natural gas boom is liquefied petroleum gas (LPG), composed of ethane and propane, both of which are key feedstocks for petrochemicals. Advanced processing is on the verge of being implemented in these facilities, which includes novel reactors, membranes and adsorption separation. All of these will contribute to lowering the capital cost, reducing the carbon footprint and enabling the US to maintain a dominant position world-wide. Technology and economic performance will be described.
CH-155 On-Site Food Waste Digestive & Liquefier Mechanisms
As food waste becomes more of an issue in the management of municipal solid waste, states and municipalities have begun to prohibit the landfill disposal of food and other organic waste. This has caused generators and disposal operators to re-think the disposal options pertaining to food waste. In urban areas, collecting organic waste is costly and typically adds another level of street congestion by necessitating a separate type of collection vehicle. Large scale composting is not viable in an urban environment. On-site food waste reduction mechanisms have been introduced in commercial operations. These units can operate economically and can effectively reduce or digest the food waste feed-stock in volume and weight of the end product -- and the putrescible fraction. This seminar will (i) review regulations which divert food waste from landfills, and (ii) analyze the technology and science behind an aqueous-based operating environment as well as a dehydrator operating environment. Lastly, there are beneficial re-uses of the end products with both the liquefier and dehydrator mechanisms.
CH-156 Nitrate Removal Technology for Well Water Systems
The EPA and permitting authorities regulate nitrate (NO3) discharges. Nitrates can be found in surface and ground water as a result of human and animal wastes and the use of fertilizers. High nitrate concentrations in drinking water present acute and long-term harm to humans, aquatic life and the environment. Nitrates can cause methemoglobinemia in infants, a condition also known as "blue baby" syndrome.
Nitrates are a form of nitrogen, which is found in several different forms in terrestrial and aquatic ecosystems. These forms of nitrogen include ammonia (NH3), nitrates (NO3), and nitrites (NO2). Nitrates are essential plant nutrients, but in excess amounts they can cause significant water quality problems. Together with phosphorus, nitrates in excess amounts can accelerate eutrophication, causing dramatic increases in aquatic plant growth and changes in the types of plants and animals that live in the stream. This, in turn, affects dissolved oxygen, temperature, and other indicators. Excess nitrates can cause hypoxia (low levels of dissolved oxygen) and can become toxic to warm-blooded animals at higher concentrations (10 mg/L) or higher) under certain conditions. The natural level of ammonia or nitrate in surface water is typically low (less than 1 mg/L); in the effluent of wastewater treatment plants, it can range up to 30 mg/L.
Sources of nitrates include wastewater treatment plants, runoff from fertilized lawns and cropland, failing on-site septic systems, runoff from animal manure storage areas, and industrial discharges that contain corrosion inhibitors.
There are a number of nitrate removal technologies. This course will review traditional methods of nitrate removal and introduce an electrolytic removal technology which does not require the use of additives (i.e. salts) and does not produce a toxic by-product. Unlike reverse osmosis or ion exchange methods of nitrate removal, the electrolytic removal technology is low-cost and, in fact, produces an end-product with beneficial re-use potential.
