The computer can limit the' power to the electric arc melting furnaces and in this manner control the demand level during peak hours. The computer can also detect meter failures. The computer system collects data which enables management to detect and analyze variations in electrical power consumption.

Development Of Industrial Energy Management Programs, Michael C. Noland

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

Energy management is a term which has only recently been entered in the business management lexicon. Until recently business managers, even the most successful ones, devoted only casual thought to the need to manage their use of fuels and electricity. Energy was cheap and plentiful. Economic sense dictated that if labor could be replaced by more energy-intense processes or equipment, the smart manager did so. Local and national policy, industrial process design, consumer habits--all these and more encouraged massive energy consumption.

A Solar-Hydrogen Energy Conversion Scheme For Agricultural Use, R. L. Reisbig, Jack L. Boone, Gordon E. Weiss, Thomas Van Doren

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

A solar energy activated system is presented which can produce hydrogen and hydrogen-derived fuels (methanol) for use on farms. The device, named "solar-kine", also can produce fertilizer (anhydrous ammonia) as a byproduct of the hydrogen. A cost analysis shows that solar-kine may be mass-producible and sold to farmers for between $7,200 and $14,700. This is equivalent to giving the fanner energy at a price of $1.79 to $3.66 per million BTU's (in 1974 dollars). Presently (Spring, 1974) regular gasoline used in tractors at 43¢ per gallon, represents a cost to the farmer of $3.77 per million BTU's. As oil-based fuels …

Introduction -- Solar And Wind Energy, Jack L. Boone

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

In recent years the scientific community has begun to explore the many alternatives of using solar energy in terms of solar energy conversion schemes. These, in general, may be classified according to use. We can talk about solar to low-grade thermo residential heating and cooling applications. We can talk about solar to high-grade heat for such applications as steam powered generation and certain high-temperature conversion processes. We can talk about solar to electrical for either residential or for large power production installations; and we can talk about wind to electrical and this would, of course, come in both large and …

Auditing Program For Effective Energy Conservation, S. Noble Robinson

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

Mallinckrodt Chemical Works has developed and is using a special audit format to identify conservation opportunities for all its utilities. Manufacturing, Utilities, R & D, and Engineering personnel are collected together for several days during which time a process or operation is subjected to an intense analyses of its utilities consumption, a brain-storming of conservation ideas, and then an "on-the-spot" engineering analysis of the economics and feasibility of each idea. This technique is a fast, comprehensive way to assess conservation potentials while committing the attention of those operating groups that can implement the ideas.

Diffusion Coefficients Of N-Heptane And N-Decane In N-Alkanes And N-Alcohols At Several Temperatures, James W. Moore, Robert M. Wellek

Chemical and Biochemical Engineering Faculty Research & Creative Works

The diffusion coefficients of the solutes n-heptane and n-decane were measured in the series of alkane solvents n-hexane through n-decane and in the alcohol solvents n-hexanol and n-heptanol. Mutual and self-diffusivities in most cases were measured at the temperatures of 20°, 25°, 30°, and 40°C. Concentrations of the diffusion species were in the infinitely dilute region. An unsteady state porous frit technique was used with carbon-14 tagged diffusion species. The diffusion coefficients measured were compared with various liquid diffusivity prediction correlations. © 1974, American Chemical Society. All rights reserved.

An Experimental Study Of Parametric Pump, Khalid Omar Ranginwala

Theses

In this research for Master's Project, the possibility for separation of glucose and fructose by parametric pumping was investigated. In this research activated carbon was used as adsorbent. First Langmuir's isotherms for glucose and fructose were experimentally found. These results were utilized in the thermal parametric pumping. The pump was run semicontinuously. Parametric pumping was also carried out with KCl +H₂O solution using a resin as adsorbent, and the 'b' value of KCl was found.

The Condensation Of Vapor On A Horizontal Rotating Square Tube., Suresh Chandra

Chemical and Biological Engineering ETDs

Heat transfer measurements were made for steam vapor condensing at one atmosphere on the outer surface of a horizontal square tube with a side of one inch, when rotated at between O and 1950 rpm. The Froude number (FR) was based on the side length. Three distinct heat-transfer regimes were observed and are correlated with FR. The first is gravita­tion controlled condensate flow when FR is less than 2.0 and the condensing film heat-transfer coefficient decreases. When 2.0

An Experimental Study Of Equilibrium Parametric Pumps, John A. Park

Theses

Parametric pumping is a separation process characterized by periodic changes in axial displacement, coupled with synchronized changes in some variable affecting the position of the interphase equilibrium. Both continuous and semicontinuous pumps were investigated at various operating conditions using a model system of toluene-n-hep-tane on a silica gel adsorbent. It has been shown that when the penetration distance for the cold cycle is less than or equal to that for the hot cycle and the height of the column, the pump has the capacity of complete removal of solute from one product stream. A quantity which is important in determining …

A Study Of Fluid Flow Entering A Sharp-Edged Channel, Rocco Racano

Theses

Experimental investigations were carried out on an newtonian fluid In the two dimensional case through the regions of a sharp-edged entrance and exit. Qualitative and quantitative results were compared to a variation of a two dimensional case of converging flow in a capillary as originally derived by Oka and proposed by Philippoff. In addition velocity profiles were taken in the entrance region. Furthermore, the effect of temperature gradients in the slit region with their resulting optical effects were considered. The methods used to obtain these goals were photoelasticity and streak photography.

Results were four, to be consistent with the theory …

Oxidation Reactions Of Unsaturated Hydrocarbons For Fuel Cells, James W. Johnson, William Joseph James, A. K. Agrawal

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

The anodic oxidation of unsaturated hydrocarbons has been the subject of numerous studies, primarily on Pt and Au electrodes at low temperatures, < 100°C. The complete oxidation to CO₂ is usually the predominant reaction with both H₂O and OH^- having been proposed as the oxygen source. Usually a single study consists of a comprehensive investigation of a single compound on a single electrode or a somewhat limited study of several compounds on a single electrode. A diversity of proposed mechanisms has resulted and is illustrated by the following summary.

History Of So2 Removal System At The Meramec Plant Of Union Electric, Gerald E. Dreifke, John F. Mclaughlin, Jerrel D. Smith

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

In line with the then emerging air pollution control regulations Union Electric installed a limestone injection wet scrubber sulfur dioxide removal system on an intermediate size coal-fired utility boiler at its Meramec Power Plant on an experimental basis in September, 1968. During approximately 3 years of operation many difficulties were encountered with plugging and scaling of various system components by calcium sulphate. As a result of this experience along with related experiences by other utilities employing similar systems, the experiment was terminated in June, 1971.

As a result of the experiences gained, however, second generation experiments in sulfur dioxide removal …

One of the areas regarding the safety is the necessity of proving that the coatings will remain intact …

Process Optimization By Flow Sheet Simulation, Larry Dale Gaines

Doctoral Dissertations

"PROPS, (Process Optimization System), has been used to simulate and optimize the Universal Oil Products solid phosphoric acid catalyst process for producing gasoline. PROPS, a modified version of CHESS (Chemical Engineering Simulation System), performs a complete design and economic evaluation of the process for each set of independent variables. The computational time during optimization was reduced by the use of a regression equation to determine K-values as a function of temperature and pressure. K-value data used for the regression was generated from the Chao-Seader correlation using mixtures of the gasoline components to be encountered during optimization. The regression equation produces …

Anionic Polymerization Of A Series Of Cyclocarbosiloxanes, William W. Knickmeyer

Doctoral Dissertations

"A study has been made on the anionic polymerization of a series of cyclocarbosiloxanes of the type: [IMAGE] where n was varied from 2 to 8. The polymerization reaction in benzene, was initiated using cesium trihexyl silanolate, a unique organic soluble liquid catalysts. Benzene served as both a solvent and to shift the position of the NMR SiCH₃ polymer peak away from the monomer peak making it feasible to follow the kinetics on a Varian EM-360 Nuclear Magnetic Resonance Spectrometer. Hexamethylphosphoramide (HMPA) was used as a promoter to solvate the initiator ions and thus increasing the polymerization rate. It …

The Anodic Dissolution Of Tin In Acidic Chloride Solutions, James W. Johnson, E. C. Liu

Chemical and Biochemical Engineering Faculty Research & Creative Works

The anodic dissolution of Sn in acidic chloride solutions (pH = -2.0 to 2.9) was studied at 25 °C. The apparent valence of the dissolving ions varied from about 0.4 to 2.4, and was a function of both electrolyte and c.d. The complexing of Sn2+ by Cl- had an important influence, with SnCl-3 apparently being the dominant product. A reaction sequence is proposed involving the stepwise oxidation of Sn, accompanied by reaction with Cl-. © 1974.

Studies On The Yield And Rate Of Lysine Production Using Brevibacterium Lactofermentum., Ho Bao Nhan

Masters Theses

"The production of lysine by a microbial method was studied. Brevibacterium lactofermentum (ATCC 21086) was used to accumulate lysine. T1\ese experiments were done in shake flasks and a 7.5-liter fermentor.

Lysine and residual glucose were determined at fixed intervals of time during each run. Cell counts were also made for some experiments. Temperature and pH were kept constant during the runs and dissolved oxygen was recorded continuously.

The effects of casamino acid, soy peptone, certain amino acids, glucose and agitation on the rate of production and the yield were studied. It appears that reducing any one of the variables will …

Study Of The Return-On-Investment Surface Of A Small Chemical Plant, Jose Antonio Casas Martinez-Ortiz

Masters Theses

"A study of the return-on-investment (ROI) surfaces for a single reactor chemical plant (Westbrook (8)) with a discontinuous investment function confirms its unimodality in the valid region. In both cases studied, the return-on-investment surfaces rise smoothly to the adiabatic boundary from a singular flow rate below which two of the component flow are not physically realizable. The optimum is located on the adiabatic boundary.

Comparison with these surfaces shows that using linear regression to obtain the parameters for an algebraic simulation of investment does not yield ROI values acceptably near the optimal. However, an heuristic approach, which assumes that minimizing …

A Study Of Pollution Abatement From The F-15 Jet Engine Test Stand, Gary Joseph Fennewald

Masters Theses

"The pollutants emitted from jet engine test stands are carbon particles, unburned hydrocarbons, carbon monoxide, and the oxides of nitrogen. This work is a study of various ways of removing these pollutants from the test stand exhaust. The methods investigated include absorption, adsorption, electrostatic precipitation, filtration, catalytic reduction and oxidation, and thermal oxidation.

For abatement of nitrogen oxides, none of the present methods is considered to provide adequate technical reliability to proceed with an installation at this time. Each of the methods for removal of nitrogen oxides has high capital and operating cost; and, in many cases, secondary pollution problems …

Modified One‐At‐A‐Time Optimization, Marshall E. Findley

Chemical and Biochemical Engineering Faculty Research & Creative Works

An optimization method has been developed that searches one variable at a time under the conditions that previously searched variables are at their approximate optimum and variables to be searched later are constant. This method provides the optimum and also information on the effects of the variables. The method is based on the Partan and Powell methods and on assuming linear partial derivatives of the objective function with respect to any given variable. The procedure involves searching each variable separately with other variables either constant or varied so that they remain at their estimated optimum for the given conditions. This …
