Monsanto's Energy Conservation Program, Ray E. Doerr Apr 1974

Monsanto's Energy Conservation Program, Ray E. Doerr

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

Energy conservation is not new to Monsanto. We have had utility and process improvement programs for many years. But the motivation of these programs was to reduce our operating costs and improve profits. However, these programs did result in substantial energy savings.

Now, however, Monsanto is placing major emphasis on a broad-scale energy conservation program for all Monsanto locations. The energy saving potential is great and is necessary because of the energy shortage as well as the rapidly escalating energy costs.


Energy Conservation In The Manufacturing Process, Paul H. Kaiser Apr 1974

Energy Conservation In The Manufacturing Process, Paul H. Kaiser

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

My presentation will cover the basic procedure used by the Emerson Electric Co. to conserve energy in Its operations. And because people frequently tell me how much they like or dislike our television sets, and how concerned they are or are not about the depth of our involvement in furnishing material for the Defense Department, at this point I would like to give a short commercial. Hopefully, it will dispel misconceptions, and define the use of energy in Emerson's operations.

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 Apr 1974

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 Apr 1974

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 Apr 1974

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 Apr 1974

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.

Four other previously reported macrocyclic polyether sulfides were also prepared. The symmetry of the nmr spectra of these compounds give added evidence for the proposed ring structures. The following subjects were presented and discussed: studies of cyclization by-products, dependence of cyclization yield on the size of the rings, high dilution principle and its application, medium-sized rings, effect of hetero-atoms on cyclization and melting point …


The Solution Photochemistry Of Benzaldehyde In Benzene, Ethanol, And 1-Hexyne, Ronald Douglas Knudsen Apr 1974

The Solution Photochemistry Of Benzaldehyde In Benzene, Ethanol, And 1-Hexyne, Ronald Douglas Knudsen

Theses and Dissertations

The photoreactions of benzaldehyde in benzene, ethanol, and 1-hexyne have been studied. Irradiation of benzaldehyde in benzene produces benzoin (I), hydrobenzoin (II), and deoxybenzoin (III). Irradiation of benzoin (I) in this solvent results in benzaldehyde formation as well as small amounts of (II) and (III). The ethanol irradiation of benzaldehyde resulted, predominantly, in the formation of (II) with (I) formed in small amounts. The photolysis of benzaldehyde in 1-hexyne produces (I), (II), (III) cis-2-heptenophenone (VII), trans-2-heptenophenone (VIII), heptanophenone (IX), and 2-(n-butyl)- 1,4-diphenyl-1,4-butanedione (X). Mechanistic pathways for the formation of these photoproducts are discussed. Separation and characterization of cis- and trans-2- …

Oxidation Reactions Of Unsaturated Hydrocarbons For Fuel Cells, James W. Johnson, William Joseph James, A. K. Agrawal Jan 1974

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 Jan 1974

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 …


Reduced Nicotinamide Adenine Dinucleotide Dehydrogenase, Piericidin Sensitivity, And Site 1 Phosphorylation In Different Growth Phases Of Candida Utilis, S. Grossman, John G. Cobley, T. P. Singer, H. Beinert Jan 1974

Reduced Nicotinamide Adenine Dinucleotide Dehydrogenase, Piericidin Sensitivity, And Site 1 Phosphorylation In Different Growth Phases Of Candida Utilis, S. Grossman, John G. Cobley, T. P. Singer, H. Beinert

Chemistry Faculty Publications

Reports in the literature indicate that during the exponential phase of growth of Candida utilis NADH oxidation is insensitive to rotenone, that rotenone sensitivity is acquired during the transition to the late stationary phase and is again lost on catabolite repression. The acquisition and loss of rotenone sensitivity appears to be accompanied by similar changes in Site 1 phosphorylation but does not appear to be reflected in the rate of oxidation of NADH (by mitochondria) or of NAD-linked substrates (by mitochondria or whole cells). In the present paper evidence is presented that these fluctuations in sensitivity to inhibitors of NADH …

Metal Promoted Reactions Of Enamino Ketones, Suhas Satchidanand Joshi Jan 1974

Metal Promoted Reactions Of Enamino Ketones, Suhas Satchidanand Joshi

Masters Theses

The reaction of 4-amino-3-allyl-3-penten-2-one (7) with mercuric acetate in acetic acid was found to produce 4-amino-1-pentene (12) in 70% yield. The scope of this unusual cleavage reaction was investigated by systematic variation of substituents on the enamino ketone framework, the metal salt and the solvent. The presence of the allyl group was necessary for the reaction to produce compound 12.

Under a variety of conditions there was no evidence for cyclization of 7 to give heterocyclic compounds. Neither was there evidence for cyclization in reactions of 4-amino-3-penten-2-one with vinyl acetate in the presence of mercury (II) or thallium (III) salts …
