Utilization of Ethanol By-Product In kenana sugar company

Abstract

Kenana Sugar Company, has always adopted a far-sighted and rounded approach to business, in keeping with this philosophy, they have diversified into other related products and services. They constantly strive as far as possible, to fully utilize all their resources both human and natural. All by-products are put to effective use in downstream utilization or value added processing, to insure that they optimize the returns on their substantial investment in kenana sugar. The aim of this research is to evaluate and know how possible can disposal the ethanol by-products especially the vinasse. Three cases studies to select the bestest and cheap solution of vinasse. This research has been directed towards the fermentation and distillation of ethyl alcohol (ethanol) for all sectors concerned with this product, including fuel, beverage and industrial alcohol. The research also explores the possibility of utilizing extra molasses from some of the other Sudanese Sugar Mills to supplement the kenana mills output, or as a potential source of feedstock for a future ethanol expansion project . Various alternatives are compared, for the utilization of the spent wash or vinasse as a feedstock for further value added products, or at least to reduce the cost of disposing of this environmentally damaging effluent emanating from the fermentation and distillation. The incineration of Vinasse after concentration and used as a boiler fuel is the best solution for disposal. With some change in the boiler burner for fuel atomization to achieve full combustion.
