Char oil energy development (Project COED). Monthly report No. 44. [Project economics for commercial plant that also produces marketable gas and that are attractive; pilot plant to process 36 tons coal/day in pyrolysis section and 30 bbl oil/day in hydrotreating section]

In 1986, the National Research Institute (NRI) adopted Harinagar to improve its energy situation. The Rural Energy Group and the Social Forestry Group of NRI were made responsible for implementation of welfare programmes in Harinagar. In the same year, NRI formed the Village Energy Development Committee (VEDC), the members of which comprised villagers and the Sarpanch. NRI, however, was beset with several problems like negative attitude of villagers towards NRI, inadequate coordination between the two groups, etc. Apte, a programme associate of the Rural Energy Group, felt that it was essential to involve VEDC, Panchayat, and villagers in a more meaningful way. The case raises some basic issues: What should be the organization structure of VEDC? What are the implications and effectiveness of the structure of VEDC as suggested by Apte? What should be the role of NRI in the envisaged structure?

Whole wheat mash fermented by Aerobacillus polymyxa was stripped of ethanol, screened, and concentrated. The resulting syrup was passed through a steam stripping column, and the levo-2,3-butanediol in the condensate was recovered by rectification. The composition of intermediate materials and products, performance of pilot plant equipment, and data and recommendations for the design of a large scale plant are given. Corrosive conditions are indicated and possible materials of construction suggested. A quantitative flow sheet and cost estimates for a commercial plant with a capacity of 1000 bu. of wheat a day are included. The daily output of such a plant is estimated to be 8460 lb. of diol (95.5% recovery), 675 gal. of 95% ethanol, 3900 lb. of dried bran, and 25,300 lb. of dried solubles. The initial cost of such a plant is estimated at $500,000. From estimates of raw materials and energy requirements the total cost of production of diol is calculated to be 17.3 cents per lb. when wheat costing $1.10 per bu. is fermented.
