Abstract:
A method and system for recapturing and utilizing low grade energy in the form of low pressure vapors generated in an industrial evaporation process. A prime mover drives a screw compressor and concurrently provides heat at several levels which is utilized in a staged evaporation system in accordance with the requirements of the stages of the system. The screw compressor recompresses the contaminated vapors to a pressure and temperature sufficient to evaporate the major fraction of moisture to be removed in the industrial evaporation process.
