There are about 274 cotton gins in the state of Texas. Of these, the majority are located in the plains and coastal regions. This means that there is a high concentration of cotton gin trash in these two areas. A stripper gin uses 2200 pounds of seed cotton to produce one bale of cotton. Of the 2200 pounds there is 500 pounds of lint, 700 pounds of seed, and 1000 pounds of trash. A picker gin processes approximately 1400 pounds of seed cotton to produce one bale of cotton. Of the 1400 pounds, there is around 500 pounds of lint, 700 pounds of seed, and 200 pounds of trash. Gin trash has a heating value of approximatley 7000 Btu per pound. Previous work has shown that financial advantages can be achieved if the energy contained in the byproducts of the gin is efficiently converted into electrical and heat power. This paper will focus on an engineering analysis of the electrical and heating requirements of a cotton gin. In addition, a feasibility study will be performed on the implementation of cogeneration to offset rising fuel prices.
