Several examples illustrating recompression of head vapors for heating the reboiler of a distillation tower are presented. The advantages of the mechanical vapor recompression system using a screw compressor are discussed in detail. The system is economically attractive with simple payback periods often less than two years. Numerous studies have identified a number of alternatives for lowering energy consumption in the distillation process through various heat recovery techniques. One such technique utilizes mechanical vapor recompression. By mechanically recompressing low-pressure vapors, a better match can be made between low-grade waste energy sources and process uses, thereby improving plant energy efficiency.
