IN-PLANT REMONSTRATION OF OPTIMIZATION OF ENERGY UTILIZATION IN BECK DYEING OF CARPEL. Proposal Part III, Phase III Extension of DOE Contract No. EY-76-S-05-5099 titled ENERGY CONSERVATION IN THE TEXTILE INDUSTRY

摘要

A proposal to demonstrate on a commercial scale an optimized procedure for beck dyeing of carpet to improve energy utilization is discussed. The proposal is for Phase III. A number of energy conserving procedural and equipment modification including lower dyeing temperature, lower liquor ratio, lower air exhaust flows, and recycle of hot spent dyebaths will be demonstrated in the plant dyeings. Pilot-scale experiments suggest that these modifications will reduce direct energy consumption in carpet dyeing by 400 Btu per pound of carpet processed. Adoption of the modified process by only 50% of the carpet industry would yield an annual reduction in energy consumption of 1 x 10 exp 12 Btu's (1.7 x 10 exp 5 BOE). The pilot-scale experiments also indicate that a cost savings of approximately 2 cents per pound of carpet dyed can be achieved with the suggested modifications. The demonstrated technology will have application in other types of nylon and polyester fiber dyeing. The Salem Carpet Mills carpet dyeing facility at Chickamauga, Georgia, will be the site of the demonstration. (ERA citation 06:012480)
