Farm-scale ethanol plant for New Zealand. Stage 3: plant operation
The report describes the operation of a farm ethanol plant, the project being Stage 3 of a wider study of the applicability of such a plant. The plant was sited at Sheffield in Canterbury and drew on the local crops of barley, potatoes, and wheat as feedstock. The report concentrates on the practical aspects of plant operation. The most significant factor affecting the viability of the project was the energy cost in opepating an electric boiler. To reduce the cost, a low-unit-rate night-time electricity tariff was essential. To meet this a large measure of automatic control was found necessary for the batch-distillation process. The best yields of ethanol obtained were: for barley, 265 litres/ton; for potatoes, 98 litres/ton; energy consumption was 11 kWh/litre. The overall conclusion is that the small scale of operation and the high energy and labour costs make the economics of such a venture unattractive.
