Are Nuclear Shipments Really Safe?, William A. Brobst
Are Nuclear Shipments Really Safe?, William A. Brobst
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The transportation of nuclear materials is on the increase. Although nuclear shipments are only a very small fraction of the Nation’s hazardous materials shipments, they attract a great deal of public attention. Shipments of spent nuclear fuel and nuclear wastes are a particular concern.
One of the many fears that people have about nuclear energy is the possibility that a nuclear shipment might somehow go awry and cause a serious public hazard. Primarily, they are worried that a shipment of spent reactor fuel or highly radioactive waste could be involved in a serious rail or highway accident and dump its …

The Energy Problem -- Crude Oil, J. A. Marshall
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
This paper discusses the national energy problem as it affects the demand for and availability of crude oil. Forecasts of energy demands to 1990 have been made based on population trends and changing life styles in the USA. Projections of energy supplies show a rapidly increasing gap between supply of crude oil and demand for crude oil from the early 1970's through 1990. The need for imported crude oil to supply the forecast deficit is discussed. The political and economic implications of these imports are also discussed. The need for refineries, port facilities, tankers, and pipelines are presented. Finally, recommendations …

The Role Of Natural Gas And Lng In Supplying Our Energy Needs, D. L. Caldwell
The Role Of Natural Gas And Lng In Supplying Our Energy Needs, D. L. Caldwell
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The domestic natural gas industry experienced a spectacular growth during the two decades from 1950 to 1970. Demand for gas continues to rise and production has peaked at a time when the price for other energy sources is escalating. A price increase can stimulate production over the short term. Massive LNG imports can help the intermediate term supply. The long term natural gas situation is bleak and substitute natural gas sources must be employed. A conservation program and reordering of priorities for energy sources is essential for the United States as well as most industrial nations.

Energy From Biochemical Sources, G. J. Fennewald, D. L. Million, Efton Park, J. L. Gaddy
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
As available energy reserves decline, renewable sources must be utilized. Organic matter, grown agriculturally, represents a renewable energy source, which is readily available. This paper reviews the methods by which organic matter can be converted to energy sources by biochemical processes. The economics of conversion of agricultural crops and byproducts to alcohols by fermentation and conversion of these agricultural materials to methane by anaerobic digestion are examined. Projections of the potential of this energy source are quite promising.

Coal And Its Derivatives As An Energy Resource, W. G. Stockton
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
April 25, 1974
Events of the last few months, it seems, have somewhat altered the public countenance of the coal industry. These events, I am sure, are the generating factors focusing interest on our industry currently, and I suspect they account for my invitation to address this distinguished group of engineering students today on the subject of coal in this nation's energy outlook.
Coal Mining is not a new industry - - it has been around a long, long time. A surprising number of people, though, have never seen any coal; they are not aware of the existence of the …
Hydrogen -- An Emerging Energy Carrier, James E. Funk
Hydrogen -- An Emerging Energy Carrier, James E. Funk
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The "hydrogen economy" envisions the energy needs of the United States in the early part of the next century being served by a network of nuclear plants producing electricity, hydrogen, and perhaps desalted water. Hydrogen is a very attractive synthetic fuel and offers appealing features as an energy carrier. This paper considers a number of factors involved in the expanded use of hydrogen including supply and demand, production techniques and transmission and storage.
Status And Outlook For Energy Conversion Via Fuel Cells, John P. Ackerman
Status And Outlook For Energy Conversion Via Fuel Cells, John P. Ackerman
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Fuel cells have the potential of providing good solutions to a variety of energy-related problems. As our supplies of conventional fossil fuels are depleted, their cost will rise, and there will be increasing difficulty in obtaining certain premium fuels at any price. It behooves us, then, to use our remaining reserves of fuels as efficiently as possible. Energy conversion via fuel cells represents one of the best ways to achieve this goal, because it is possible, simultaneously, to obtain more work and less pollution from a dollar's worth of fuel with a fuel cell than with any other device.

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A significant reduction in energy consumption per barrel of crude oil processed has been effected at Shell Oil's Wood River, Illinois, Refinery during the past two years. Some of the projects which have resulted in reduced energy consumption are:
1. Improved furnace efficiency through closer surveillance and through installation of optimizing controllers on certain furnaces.
2. Lowered reflux-to-feed ratios on certain fractionating columns following reoptimization of operating conditions with current fuel values.
3. Additional heat exchangers purchased and installed on plants originally designed and optimized at lower fuel values.
This paper discusses examples of each of the above projects and …
An Overview Of Natural Gas Supply And Availability, D. E. Gibbs
An Overview Of Natural Gas Supply And Availability, D. E. Gibbs
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Natural gas presently supplies almost one-third of the total U.S. energy supply--and like oil, has had its proven reserves reduced by ever-increasing production. The potential gas reserves of the United States are sufficient to maintain our present demand for a considerable period of time, if these reserves can be found. The exploration necessary has to be financed by increased gas cost. Additional technology will be necessary to increase the amounts of gas that can be produced from our present and future supplies. Several methods of obtaining the capital necessary to perform the additional drilling and areas of technical improvement are …
Bellamy Field Tests: Recovery Of Medium Gravity Crude Oil From Missouri Tar Sands By Counterflow Underground Burning, J. C. Trantham
Bellamy Field Tests: Recovery Of Medium Gravity Crude Oil From Missouri Tar Sands By Counterflow Underground Burning, J. C. Trantham
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
In the current energy shortage, the heavy oil and tar sands of the United States are assuming critical importance. This is true for at least two reasons: first, they constitute a major resource, amounting to some 150 billion barrels in place; and second, their where-abouts is known -- exploration will not contribute to the lead time required for bringing these resources into the national energy picture. Moreover, many of the technological problems have been solved. The delay in producing these heavy oil and tar deposits is due primarily to economics.

Energy And The Environment, Joseph T. Zung
Energy And The Environment, Joseph T. Zung
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The topic of Energy and Environment is probably the most timely one at present time. Probably it is not because both energy and environment are man's most precious resources we want to conserve, but because of their seemingly contradictory and mutually destructive nature. One often asks ourselves these days: Is the energy crisis an environmental problem or environmental restrictions caused our present energy crisis?
A Technique For Improving Stability Of Petroleum Reservoir Simulation Models, M. D. Arnold, T. C. Wilson, A. Herbert Harvey
A Technique For Improving Stability Of Petroleum Reservoir Simulation Models, M. D. Arnold, T. C. Wilson, A. Herbert Harvey
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Computational instability may occur in the mathematical simulation of hydrocarbon reservoirs when small inaccuracies in the calculated pressures cause loss of diagonal dominance in the matrix of coefficients. The problem can be resolved by the use of a more precise technique for computation of pressures. However, this stability problem is still troublesome to users of certain types of reservoir simulators. A computational technique which has been found effective in resolving the problem is presented.

Solar-Thermal Energy Conversion, E. R. G. Eckert
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The fact that our conventional fuel resources are finite and will be exhausted some time in the future gives impetus to a consideration of solar radiation for conversion into heat or electric power. The characteristics of the solar radiation - that the enrgy flux density is small and that it arrives intermittently on the ground of our glove has to be considered in any system utilizing this energy source. For home heating parts of the roof offer a sufficiently large area, for electric power production areas of some km2 are required to collect a sufficient amount of energy. Optical …

Let me share with you a quotation from a report issued bv the Chase Manhattan Bank while the Arab oil embargo was still in effect. "Reportedly, the annual cost of a gasoline rationing program would amount to $1.4 billion. Based upon past results, if that much money was devoted to an exploratory effort, it would be potentially capable of discovering more than 2 billion barrels of petroleum. That amount of petroleum would be equal to 19 percent more than all the gasoline consumed in privately owned automobiles in 1973."

Interfaces Of Steam Electric Power Plants With Aquatic Ecosystems, Gerald J. Lauer, William T. Waller, Guy R. Lanza
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Growth and reproduction may be stimulated by increased temperature in the cooling system and thermal plume during seasons when ambient water temperature is less than optimum, but growth, reproduction and survival are reduced when the elevated temperatures become excessive. Some fish species congregate in the warm thermal plumes during cold seasons but are excluded from this living space by temperatures above their preference in the summer. However, the warm refuge provided by a thermal plume in cold seasons can be a death trap if a power plant shuts down suddenly and exposes the fish to cold shock exceeding their lower …
