Mechanical vapor recompression for waste energy recovery
This paper is concerned with energy recovery in petroleum distillation processes utilizing mechanical vapor recompression. 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. The paper describes the merits of mechanical vapor recompression, using a screw-type compressor for recovering energy at the distillation tower, and how it can be accomplished by using an intermediary fluid such as steam or by recompressing the distillation column vapors directly.
