Banquet Speaker: Energy -- What We Must Do, Peter Van Nort Oct 1978

Banquet Speaker: Energy -- What We Must Do, Peter Van Nort

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

You have heard for the last two days and will hear tomorrow relative to energy what people are planning, what is being researched, what is proposed, what is possible, what is being tested, etc. I would like to tell you what each of us must do relative to energy. I hope you will excuse me for being presumptuous….

The message might better be called a plea -- a plea from one person committed to the great- ness of this country and more importantly, committed to its survival in its present form….

We are in a crisis….Never before have we run …


Heat Recovery System For Glass Melting Furnace, Milton J. Murry Oct 1978

Heat Recovery System For Glass Melting Furnace, Milton J. Murry

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The installation and operating of a 100 ton per day glass melting furnace by Flat River Glass Company to make specialty bottles provided an excellent opportunity for recovery of waste heat. The furnace operates at 2300°F, and four feeders to bottle making machines operate at 2100“F. The 120,000 s.f. packaging area is next to the furnace bay, and it is heated solely by reclaimed heat from the melting furnace bay.

There are two systems that are used to transfer this waste heat from the furnace area to the packaging area. The first of these systems is a water loop. Water …


An Analysis Of Solar Heating Costs In Arkansas Broiler Houses, Ralph Gunderson, J. Martin Redfern Oct 1978

An Analysis Of Solar Heating Costs In Arkansas Broiler Houses, Ralph Gunderson, J. Martin Redfern

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This study is based on the computer simulation model of a solar heated broiler house in four locations in Arkansas. This simulation model estimated the annual energy savings in each broiler house due to the installation of a solar heating system. This paper uses present value analysis to estimate the life cycle costs of heating conventional and solar heated broiler houses in the state of Arkansas. From these calculations, the number of years required to achieve a break-even cost of heating is estimated.


The Development Of Coal-Based Emulsions And Their Potential Impact On The National Economy, Murphy I. Song Oct 1978

The Development Of Coal-Based Emulsions And Their Potential Impact On The National Economy, Murphy I. Song

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The proposed national energy policy emphasizes the use of coal replacing oil and gas. Coal-oil mixture (COM) can be produced using techniques developed in recent years to replace oil and gas. Large existing utility and industrial boilers could be converted to bum COM by retrofitting the boilers. In addition, the COM provides definite financial advantages to the owners of large utility and industrial boilers. The use of COM impacts on the national economy through new investment for retrofitting utility and industrial boilers, through reduced importation of residual oil, and through increased demand for coal.


Usable Energy Resources Expand Under The Economic Pressures Of Fuel Scarcity, Raphael Shen Oct 1978

Usable Energy Resources Expand Under The Economic Pressures Of Fuel Scarcity, Raphael Shen

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Until mankind finds properties in materials that are useful and usable under given economic conditions, these materials are not resources. In the past, many of them became usable as the ones they replaced became scarce and expensive. Market induced R & D toward profit seeking and cost minimization hastens to incorporate currently unused materials into the productive processes. With the increase in oil and natural gas prices, hitherto untapped energy sources present themselves as attractive alternatives. There will be no permanent shortage of energy resources, and the current energy crisis will be a page of past history in the foreseeable …

Comparison Of Stirred And Immobilized Cell Reactors For Ethanol Production, Oliver C. Sitton, J. L. Gaddy Oct 1978

Comparison Of Stirred And Immobilized Cell Reactors For Ethanol Production, Oliver C. Sitton, J. L. Gaddy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Biomass can be converted to sugars by hydrolysis with enzymes or mineral acids. These sugars can be converted into a number of chemical intermediates in biological reactors. Biological reactions are generally slow and selection of the most efficient reactor is important in these applications.

Immobilized cell reactors allow high cell densities and high throughput by attaching microorganisms to a fixed support. This paper compares the rate of production of ethanol from glucose by Saccharomyces Cerevisiae in a packed column and a stirred reactor.

Continuous stirred reactor studies showed a washout rate of .27 hr-1. The optimum rate of …

Development Of A New Technique For The Analysis Of Pesticides In Water, Prasad K. Kadaba, Pramode K. Bhagat, Radko Osredkar, V. R. K. Murthy

KWRRI Research Reports

A Nuclear Double Resonance Spectrograph has been designed and constructed with emphasis on quadrupolar nuclei of half-integral spins. The use of a data acquisition and processing system featuring the A/D converter, signal averager with built in fast Fourier transformation hardware greatly improves the S/N ratio. The spectrograph has been used to detect certain organochlorine, carbamate and symmetrical triazine pesticides. Concentration levels that can be detected range from 15 to 100 micrograms per liter. Since the measurements are done below ice temperatures, heat-labile compounds can be detected without conversion to more suitable derivatives as in gas chromatography. Fats and oils in …


Influence Of Nitrogen Fertilization On The Quality And Quantity Of Streamflow From A Forested Watershed, George B. Coltharp, Michael T. Shearer, Everett P. Springer, Robert F. Wittwer Oct 1978

Influence Of Nitrogen Fertilization On The Quality And Quantity Of Streamflow From A Forested Watershed, George B. Coltharp, Michael T. Shearer, Everett P. Springer, Robert F. Wittwer

KWRRI Research Reports

This project was designed to determine the effects of nitrogen fertilization on the quality and quantity of streamflow eminating from an eastern hardwood forest watershed. A 40.67 ha watershed, located in mountainous eastern Kentucky, was aerially fertilized in late April 1975. The forest stand was principally oak, hickory, and yellow poplar, 50 - 55 years of age and in a relatively undisturbed condition. A helicopter applied anunonium nitrate at a rate of 504 kg/ha. Because a large part of applied nitrogen fertilizer ends up in the highly mobile nitrate nitrogen.form, this is the principal ion monitored in this study. No …


A Proposed Revision Of Kentucky's Water Rights Legislation, Richard Ausness Oct 1978

A Proposed Revision Of Kentucky's Water Rights Legislation, Richard Ausness

KWRRI Research Reports

Kentucky's present system of water law consists of a statutory water withdrawal permit system superimposed upon a body of common-law water rights doctrine. The rights of water users are often uncertain under this system, particularly in periods of water shortage. The proposed revision of Kentucky's existing water rights legislation, would greatly reduce the significance of common-law water rights and would remedy some of the weaknesses in the present statute.

Part 1 of the proposed statute establishes an administrative structure; Part 2 deals with water withdrawal permits; Part 3 retains the present statute's provisions on the regulation of dams and impoundments, …
