Title: Energy generation from cotton gin trash: an economic analysis

Technical Report ·
OSTI ID:5783659

This study consists of economic analyses of electric power generation and low-Btu (British thermal unit) gas generation from cotton gin trash. Both analyses consider the use of a large gin, sized at 40,000 bales per year. A fluidized-bed combustor is used to produce the low Btu gas and in conjunction with a boiler and turbine to produce electricity. For this case study, the consideration of economic feasibility involves the saving of the cost of energy not purchased, the sale of surplus electricity, and the saving of the cost of gin trash disposal eliminated; all are results of on-site energy generation. Electricity requirements will be satisfied, and waste heat will be used for cotton drying. The savings that would result from these two measures total about $126,000 (based on a 300,000 Btu per bale requirement for cotton drying with natural gas priced at $2.50 per thousand cubic feet and electricity priced at 4 cents per kWh).
