Application Of Treated Oil Sands Drill Cuttings Waste In Micropiles Construction, Moustafa Ahmed Raafat Mohamed Aboutabikh Jan 2016

Application Of Treated Oil Sands Drill Cuttings Waste In Micropiles Construction, Moustafa Ahmed Raafat Mohamed Aboutabikh

Electronic Thesis and Dissertation Repository

A micropile is constructed by drilling a hole, placing a steel reinforcing element, grouting it using neat cement. However, cement production consumes energy and generates carbon dioxide. Implementing waste materials in construction applications represents a sustainable solution for many waste management problems. On the other hand, oil sands drill cuttings waste represents one of the most difficult challenges for the oil sands mining sector. Reducing the amount oil sands drill cutting waste sent to landfill offers one of the best solutions for waste management. This thesis presents an innovative solution for application of treated oil sands waste (TOSW) in grout ...


Modeling Explosive Lensing On A Cylindrical Body In Air: A First Step Towards Sealing An Underwater Offshore Oil Spill, Phillip R. Mulligan Jan 2016

Modeling Explosive Lensing On A Cylindrical Body In Air: A First Step Towards Sealing An Underwater Offshore Oil Spill, Phillip R. Mulligan

Doctoral Dissertations

"In 2010, the British Petroleum (BP) Deepwater Horizon accident leaked oil into the Gulf of Mexico for 87 days. A fast response method that can seal an oil pipe and stop the release of oil is needed in order to prevent future oil leaks from turning into ecological and financial disasters. Explosives can serve this need.

This research examined how a circular implosive discontinuous explosive lens interacts with a cylindrical surface. The following research was designed to study the applicability of the Method this author developed to predict the peak pressure from multiple shockwaves converging on a centrally located cylinder ...


A Petrophysical Evaluation For Permeability Of A Gas Reservoir In The Taranaki Basin, New Zealand, Musa Cetin Jan 2016

A Petrophysical Evaluation For Permeability Of A Gas Reservoir In The Taranaki Basin, New Zealand, Musa Cetin

Dissertations, Master's Theses and Master's Reports

The goal of this study was to evaluate permeability and study the controls on permeability in a gas saturated formation. Conventional well logs, mineral identification crossplots and empirical models were applied to analyze different lithologic and diagenetic features and to examine the effect that these features may have on the reservoir. An unusual feature was observed, and required detailed examination: there existed (in two wells) five zones of lower resistivity (higher water saturation) above the gas-water contact. This is unexpected, as above that contact, the water is usually at irreducible water saturation. I conclude that the lower resistivity (the higher ...


Evaluation Of The Removal Of Organic Sulfur From Coal, R. Markuszewski, L.J. Miller, W.E. Straszheim, C.W. Fan, Thomas D. Wheelock, R.T. Greer Jan 1981

Evaluation Of The Removal Of Organic Sulfur From Coal, R. Markuszewski, L.J. Miller, W.E. Straszheim, C.W. Fan, Thomas D. Wheelock, R.T. Greer

Chemical and Biological Engineering Publications

As the removal of sulfur from coal prior to combustion acquires more importance in order to meet evermore stringent antipollution regulations, research on the development of methods for the cleaning of coal continues to expand. Reviews are available which describe the various methods for desulfurizing coal (1, 2, 3). The sulfur content in coal is usually a few per cent, but it can range from less than 0.5 per cent to as much as 8 per cent or more. Much of the sulfur is inorganic in nature, occurring in discrete mineral phases; the inorganic sulfur is mostly pyrite with ...

The Energy Conservation Implications Of Master Metering Of Electric Service In Apartments, Gordon Gross Oct 1975

The Energy Conservation Implications Of Master Metering Of Electric Service In Apartments, Gordon Gross

UMR-MEC Conference

A study has been made of the difference in electricity usage between residents of "Electricity included" apartments and those tenants who pay individual "light bills." The factors which influence owners' and builders' choices of metering service are discussed in detail.

Data taken from over 100 apartment buildings or complexes in 10 major U.S. metropolitan areas and from over 50 major electric power companies are used as the basis for the reported results. Contractors estimates of the costs to convert building service from master to individual meter and some bases for these costs are presented.

The energy conservation potential which ...


Solar Assisted Power Systems, A. G. Potter Oct 1975

Solar Assisted Power Systems, A. G. Potter

UMR-MEC Conference

Except for hydroelectric power, solar electric generation has not been widely used in the past to assist power system generation because of its relatively high cost. This situation has now started to change with the advent of the energy crisis as exemplified by decreasing natural gas supplies and increasing fossil fuel prices. One possible response to this situation which appears to have a relatively good chance for economic success is the utilization of wind and solar thermal energy for space and water heating loads served by natural gas or electric power. Unfortunately, a large portion of the energy collected in ...


Energy Conservation In Uniroyal, Inc., John C. Madigan Oct 1975

Energy Conservation In Uniroyal, Inc., John C. Madigan

UMR-MEC Conference

In the last year, rapid developments have led to the establishment of industry conservation goals and monitoring by the Department of Commerce and the Federal Energy Administration via the various industry associations.

Since 1972, Uniroyal has progressed more than half way toward the 1980 goal of 15% established for the rubber and chemical industries. This paper will describe details of the program with emphasis on new input, such as the computerized tracking method now in use.

Plant studies have provided an assessment of "base" loads vs. process loads, important when considering unit energy consumption. These vary, particularly with the climate ...


Energy Conservation Program At Ralston Purina, George A. Bossman Oct 1975

Energy Conservation Program At Ralston Purina, George A. Bossman

UMR-MEC Conference

While the food industry as a whole uses only about 5 per cent of total manufacturing energy, we at Ralston Purina Company recognize our dependence upon energy and the importance of a strong energy management program. Last year, as part of this program, we established and implemented an energy conservation program designed to identify opportunities for conservation.

The major thrust of this program has been directed at manufacturing facilities where usages can be traced, wastes detected, and appropriate action taken. These are separate from a general overall corporate effort to make employees more energy conscious in every phase of their ...

Wind Energy Concentrators, John L. Loth Oct 1975

Wind Energy Concentrators, John L. Loth

UMR-MEC Conference

This paper presents two alternatives to the shrouded propeller wind energy concentrator. Their operation is based on generating a low pressure area, with high local wind velocity, around the windmill rotor.

The two types of wind energy concentrators considered are: (1) the "obstruction type" concentrator where a vertical cylinder or vertical flat surface is used to produce high local velocities around two counter-rotating vertical axis rotors, and (2) the "vortex type" concentrator where a horizontal vortex is generated by a vertical high lift wing of finite span. The high local wind kinetic energy inside the vortex is harnessed by a ...


Centralized Solar Wind Home Heating, Russell Peterson, Duane Cromack Oct 1975

Centralized Solar Wind Home Heating, Russell Peterson, Duane Cromack

UMR-MEC Conference

In the immediacy of national goals for energy independence, the need emerges to use dialectic methods to diminish the energy consumptive characteristics of the typical home.

At the cutting edge of resourceful progress are the residential developments which embrace alternative and conservative energy techniques. In conjunction with such a planned, low impact community, this paper proposes a cluster-centralized system which utilizes wind energy in combination with solar thermal energy for space and domestic water heating.

A description of the random solar-wind resource embodies a matching problem that in turn reveals the benefits of the combined mode of energy collection. Though ...


Osmo - Power. Osmotic Work; Energy Production From Osmosis Of Fresh Water/Sea-Water Systems, H. H. G. Jellinek Oct 1975

Osmo - Power. Osmotic Work; Energy Production From Osmosis Of Fresh Water/Sea-Water Systems, H. H. G. Jellinek

UMR-MEC Conference

It is imperative that new and ecologically acceptable energy sources are made available. Solar energy is a source which seems to be inexhaustible and free of pollution hazards. One vast source, which can be considered to be a solar energy source consists of the system fresh water/sea water. Fresh water is continually removed by the hydrological cycle where water evaporates from the ocean due to solar radiation and is eventually precipitated again in the form of fresh water feeding various rivers. Fresh water and ocean (salt) water mix when rivers flow into the oceans. The different chemical potentials are ...


Energy From Agriculture, E. C. Clausen, D. L. Million, Efton Park, J. L. Gaddy Oct 1975

Energy From Agriculture, E. C. Clausen, D. L. Million, Efton Park, J. L. Gaddy

UMR-MEC Conference

During the past few years, the demand for energy and petrochemicals has grown at a pace so rapid that our reserves of fossil fuels, once considered inexhaustible, are now being quickly depleted. To help lessen this impending problem, alternative sources of energy must be rapidly developed.

Of the many new sources of energy being studied, solar energy, undisputedly, is the most inexhaustible. Energy from the sun, incident upon the earth's surface, exceeds by nearly three orders of magnitude the total energy consumption today. Furthermore, it is not subject to nationalistic boundaries and its use would be compatible with our ...

Energy And Transportation Policy, James S. Sagner Oct 1975

Energy And Transportation Policy, James S. Sagner

UMR-MEC Conference

This paper presents experimental data which exemplifies the differences in emission level testing on internal combustion engines when dynamic engine tests are used instead of steady-state engine tests. A comparison of the two test methods is made using hydrocarbon fuels with varying amounts of methanol. Emissions measured include the nitric oxides, unburned hydrocarbons and carbon monoxide. Emission levels and fuel consumption are reported for the various volumetric percentages of methanol in the fuel.

Of special significance are the different trends the emission levels establish when subjected to a dynamic engine test as compared to the results for the steady-state tests ...


Ways To Reduce Peak Electrical Demand In South Louisiana, S. J. Gold, M. D. Bakewell, G. E. Guidry, E. F. Lewis, L. J. Naquin, B. P. Whitney Oct 1975

Ways To Reduce Peak Electrical Demand In South Louisiana, S. J. Gold, M. D. Bakewell, G. E. Guidry, E. F. Lewis, L. J. Naquin, B. P. Whitney

UMR-MEC Conference

This study analyses alternatives for coping with the peak electrical demand of hot summer afternoons. Economic and Political aspects, as well as technical feasibility, are included. It is concluded that South Louisiana may indeed be able to trim peak demand to 5% below what is anticipated by 1980 , thus making one of the coal fired stations scheduled then unnecessary. However, the contingencies (Natural Gas Shortage, Another Oil Embargo) would make a coal-fired station very desirable.


Alternative Approaches To Energy Modeling, Alan S. Cohen, Kenneth W. Costello Oct 1975

Alternative Approaches To Energy Modeling, Alan S. Cohen, Kenneth W. Costello

UMR-MEC Conference

The effects of government and private sector energy policies are varied and interrelated. Before implementing research and development programs, new technologies, environmental and price regulations, import quotas, and other energy-related policies, the consequences of these programs must be identified and quantified on a regional basis. To evaluate the regional impacts of energy policies, we need to consider production costs, transportation costs, and the location of reserves, as well as the demands for energy and nonenergy goods. Developing techniques for analyzing these factors was the objective of many previous research efforts. The strengths and weaknesses of the resulting models are discussed ...

Energy Management In The Food Store, Paul Adams Oct 1975

Energy Management In The Food Store, Paul Adams

UMR-MEC Conference

Food store refrigeration is vital to the food distribution system and consumes much of the energy used in a supermarket. The manufacturers of food store display equipment have worked long and hard to develop new ideas in supermarket energy conservation. Hussmann's studies have uncovered a number of facts invaluable to anyone concerned with energy conservation in the supermarket.

The first fact is to realize that supermarkets are different from any other retail stores. They consume more energy each year per sq. ft. of store - or per customer - or per dollar sales than other retail stores and most commercial businesses ...


Efficiency In The Use Of Energy Has Been Effected Through Industrial Use Of Subsurface Space, Truman Stauffer Sr. Oct 1975

Efficiency In The Use Of Energy Has Been Effected Through Industrial Use Of Subsurface Space, Truman Stauffer Sr.

UMR-MEC Conference

Our Nation, with its high standard of living made possible by industrialization, draws heavily on energy producing natural resources. Self reliance mandates the use of every measure of conservation in order to extend the yet finite supply of energy to meet our national needs. Efficiency in the use of energy has been and can increasingly be effected through industrial use of subsurface space. The use of mined rooms for industry and warehousing utilizes the natural stable underground temperature and the low coefficient of heat transfer existing naturally in the lithosperic materials of the subsurface environment. The small amount of energy ...


Planned Reduction In Electrical Energy Use In Nashville - Davidson County, Tennessee: A Preliminary Assessment, Barry D. Lichter, William F. Flanagan, Robert S. Goodrich, James K. Sebenius, C. Paul Beach Oct 1975

Planned Reduction In Electrical Energy Use In Nashville - Davidson County, Tennessee: A Preliminary Assessment, Barry D. Lichter, William F. Flanagan, Robert S. Goodrich, James K. Sebenius, C. Paul Beach

UMR-MEC Conference

An assessment was carried out of the impacts of the various alternative strategies designed to reduce the rate of electrical energy use in the Nashville-Davidson County area, in the light of a potential crisis in supply. Seven strategies were identified among the major categories of voluntary reduction, price regulation, and mandatory reduction. Thirty-three sub-sectors were identified among residential, commercial and industrial users, and the consequences of imposing the strategies were assessed using a cross-impact matrix. The value of the methodology as an aid to public policy formulation lies in its possible extension to allow direct participation of various affected publics.


The Design And Performance Of A Distributed Flow Water-Cooled Solar Collector, Theodore F. Smith, Herbert R. Flindt Oct 1975

The Design And Performance Of A Distributed Flow Water-Cooled Solar Collector, Theodore F. Smith, Herbert R. Flindt

UMR-MEC Conference

Design of a flat plate collector which reduces the temperature differential between the absorber plate and the fluid is described. The reduced temperature differences are shown to yield increase collector performance. Flow characteristics of the collector are examined. Collector thermal performance is illustrated for typical operating and environmental conditions. A cost analysis is presented to demonstrate that material and assembly costs are substantially lower than for any collector presently on the market.


Choosing Alternative Energy Systems Under Conditions Of Uncertainty, Dennis Costello Oct 1975

Choosing Alternative Energy Systems Under Conditions Of Uncertainty, Dennis Costello

UMR-MEC Conference

A methodology for simulating the decision process of an investor deciding between alternative energy systems is presented. The approach assumes the investor bases his decision on cost (or rate of return) and risk. Risk is treated directly in the model and not reduced to a certainty equivalent. The rate of return-risk characteristics of many system combinations allows them to be eliminated as viable choices to the investor without reference to his personal attitude toward risk.


Energy, Environment And Incremental Decision Making, Jeff V. Conopask Oct 1975

Energy, Environment And Incremental Decision Making, Jeff V. Conopask

UMR-MEC Conference

During the late 1960's and early 70's a variety of environmental/energy oriented legislation was enacted by the Congress. The most important of these acts, the National Environmental Protection Act (NEPA), required that environmental impact statements be filed when various private and public activities have a potential for impacting man and his environment. (17) Impact statement requirements go beyond the currently practiced cost/benefit analysis, which is often just a production (direct) impact assessment. Heretofore, indirect or second round economic and social effects of consequence affecting other national goals were seldom counted.


Natural Resource Pricing And Economic Development, Vaman Rao Oct 1975

Natural Resource Pricing And Economic Development, Vaman Rao

UMR-MEC Conference

In a competitive equilibrium the price of a natural resource will be increasing at a rate equal to the social time preference rate, but in a monopoly market, the price will be increasing at less than social time preference rate. If the producer countries utilise their monopoly of production and sale of a natural resource for the purpose of developing their economies, the price of the natural resource will be growing at the rate at which the producer countries' economies are growing, whether or not the sales proceeds are used to finance their investment programmes, fully or partly.


Oil Shale R & D -- A Bureau Of Mines Program, Steve Utter Oct 1975

Oil Shale R & D -- A Bureau Of Mines Program, Steve Utter

UMR-MEC Conference

Energy is one of our basic natural resources. Oil constitutes an important part of this resource but domestic production is dropping while imports are rising. Today, oil represents about one-half of the total energy consumed in this country, and demand is expected to grow at the rate of about 2 percent per year during the next 10 years. Increased reliance on imports can be reduced by synthetic fuels produced from the oil shale deposits of the Green River Formation in Colorado, Utah, and Wyoming. These deposits are so enormous (600 billion barrels in high- grade shale alone), that any limitations ...


Direct Ac Generation From Solar Cell Arrays, Fernando L. Alvarado Oct 1975

Direct Ac Generation From Solar Cell Arrays, Fernando L. Alvarado

UMR-MEC Conference

Results of the investigation of the performance of solar cells when directly coupled to a conventional three-phase power network are presented. This approach dissociates the electricity production problem from the electric energy storage problem. Extensive studies of the required power inverter are performed. Preliminary simulation results indicate that ac power outputs of better than 90% of the optimum cell power output can be easily achieved by means of a suitably controlled inverter, thereby justifying the elimination of dc loads or local dc electric energy storage devices. It is also shown that the controlling policy for the inverter must depend on ...
