APPLICATIONS OF THERMAL ENERGY STORAGE TO WASTE HEAT RECOVERY IN THE FOOD PROCESSING INDUSTRY, Final Report
A project is discussed in which the possibilities for economical waste heat recovery and utilization in the food industry were examined. Waste heat availability and applications surveys were performed at two manufacturing plants engaged in low temperature (freezing) and high temperature (cooking, sterilizing, etc.) food processing. The surveys indicate usable waste heat is available in significant quantities which could be applied to existing, on-site energy demands resulting in sizable reductions in factory fuel and energy usage. At the high temperature plant, the energy demands involve the heating of fresh water for boiler make-up, for the food processes and for the daily clean-up operation. Clean-up poses an opportunity for thermal energy storage since waste heat is produced during the one or two production shifts of each working day while the major clean-up effort does not occur until food production ends. At the frozen food facility, the clean-up water application again exists and, in addition, refrigeration waste heat could also be applied to warm the soil beneath the ground floor freezer space. Systems to recover and apply waste heat in these situations were developed conceptually and thermal/economic performance predictions were obtained. The results of those studies indicate the economics of waste heat …

Cadmium sulfide/copper sulfide heterojunction cell research. Quarterly technical progress report, February 26-May 31, 1979
All-vacuum sputter deposited heterojunction solar cells of the CdS/Cu/sub 2/S and Cd/sub 1-x/Zn/sub x/S/Cu/sub 2/S types have been fabricated on glass substrates by dc reactive sputtering using cylindrical-post magnetron sputtering sources and Ar-H/sub 2/S working gases. The rear electrode is Nb. The top grid electrode is Au sputter deposited through a mechanical mask. Preliminary measurements on nonoptimized cells have yielded efficiencies of about 0.4% with short circuit currents of about 3 mA/cm/sup 2/, open circuit voltages of about 0.35V and fill factors of about 0.37. Extensive modifications are being made to the deposition apparatus which will permit greater control over the process variables and optimization of the cells. A series of experiments are reported which indicated that at the high deposition temperatures used for the Cd(Zn)S deposition (approx. 300/sup 0/C), an electrically active impurity, capable of influencing both the series resistance and the junction behavior of the cells, may pass from the Nb into the Cd(Zn)S.

Catalytic conversion of oxygenated compounds to low molecular weight olefins. Progress report, January 1-July 31, 1979. [Methanol from synthesis gas from coal gasification]
An attractive route for producing ethylene and propylene from coal is to gasify the coal to produce synthesis gas, convert the synthesis gas to methanol, and then convert methanol to the olefins. During this report period the reactions of methanol over chabazite ion exchanged with rare earth chlorides have been studied at reciprocal liquid hourly space velocities of 1.5 to 15, at temperatures of 259, 271, 304, 352, and 427/sup 0/C, and at pressure 2.7 atm. At 259 and 271/sup 0/C the principle product was dimethyl ether. As the temperature was increased the conversion of methanol to olefins and alkanes increased to 54% and 32%, respectively. A mixture of dimethyl ether, water, and methanol was fed to the Berty reactor. This mixture was near the equilibrium concentrations for converting pure methanol to dimethyl ether and water at 275/sup 0/C. The Berty reactor temperature was 427/sup 0/C. Initially the yields were similar to those obtained when feeding pure methanol. However, the catalyst activity decreased at a faster rate. Rate models are being developed to correlate the catalyst activity and rate as a function of time on stream and partial pressures. A promising model is presented.

Continuation of systems study of fuels from grasses and grains: Phase 2 and Phase 3. Final report
Results are presented of an investigation of biomass-derived fuels from grasses and grains. A region-by-region analysis of biomass production, with both the present (near-term) and the future (mid-term) being considered is presented. The overall approach for analysis of the near-term involved least cost analysis of production, transportation, and energy conversion. The mid-term analyses were structured around the assumed implementation of modified crop production systems in which land was more extensively used in a given region, improved crop management practices were used, and the crop mixes were significantly altered from the present. The production systems in the several regions were combined with conversion plants ranging in size from 500 oven-dry (OD) tons/day to 3000 OD tons/day, or an energy imput of 75 x 10/sup 8/ Btus to 45 x 10/sup 9/ Btus using 7500 Btus/lb. The conversion processes consisted of anaerobic digestion, fermentation, direct combustion, and thermochemical conversion. The latter process was also considered in the context of production of ammonia and methanol.

Demonstration plant supplementary technical studies section 10-confidence analysis. SRC-II demonstration project, phase zero, task number 1, deliverable number 3
The Gulf Management Sciences Group (GMSG) in Pittsburgh was asked to provide assistance in performing a confidence analysis for the SRC-II demonstration plant as required by the Department of Energy. Specifically, the contract says to discuss confidence levels for plant operating and capital costs; plant operability and technical risk. It was decided that the best way to obtain estimates for these variables would be through interviews of people with substantial experience in the field. Each subject was first asked what modifications he envisioned being made to the current plant design. Discussion was limited to major systems that might require partial redesign and comments concerning the plant in general. The interviewees were next asked to estimate the probability of success for the project, given that the modifications they envisioned were in fact made. The modes of the combined distributions of the interview results indicate that the respondents in general felt that the base case estimates represented the most probable outcomes with the possible exception of the capital cost estimate. On the other hand, the respondents consistently judged that there is a chance that the demonstration plant will perform significantly worse than the base case for each of the variables that were …

Feasibility study for anaerobic digestion of agricultural crop residues. Dynatech report No. 1935
The objective of this study was to provide cost estimates for the pretreatment/digestion of crop residues to fuel gas. A review of agricultural statistics indicated that the crop residues wheat straw, corn stover, and rice straw are available in sufficient quantity to provide meaningful supplies of gas. Engineering economic analyses were performed for digestion of wheat straw, corn stover, and rice straw for small farm-, cooperative-, and industrial scales. The small farm scale processed the residue from an average size US farm (400 acres), and the other sizes were two and three orders of magnitude greater. The results of the analyses indicate that the production of fuel gas from these residues is, at best, economically marginal, unless a credit can be obtained for digester effluent. The use of pretreatment can double the fuel gas output but will not be economically justifiable unless low chemical requirements or low cost chemicals can be utilized. Additional development is necessary in this area. Use of low cost hole-in-the-ground batch digestion results in improved economics for the small farm size digestion system, but not for the cooperative and industrial size systems. Recommendations arising from this study are continued development of autohydrolysis and chemical pretreatment of …

High-temperature process-steam application at the Southern Union Refining Company, Hobbs, New Mexico (solar energy in the oil patch). Phase I design. Final report
Southern Union Refining Company's Famariss Energy Refinery has worked diligently with Monument Solar Corporation in the conceptual and detail design for this unique application of solar generated steam. An area closely adjacent to the refinery and fronting New Mexico State Highway No. 18 has been designated for the solar collector array. Space planned for the demonstration parabolic trough array is sufficiently large to handle an array of 25,200 square feet in size - an array more than twice the size of the 10,080 square feet proposed originally. The conceptual design, performance, safety, environmental impact, and economic analysis are described. Engineering drawings are included. (WHK)
