Techno-economic Analysis and Selection for the Desalination in Power Plant

This paper describes the principles of membrane method and low-temperature multi-effect distillation desalination,conducts technical and economic comparison analysis on the equipment of low-temperature multi-effect distillation desalination and multi-sets reverse osmosis desalination and contrasts the integrated water costs and operation costs.The results show that: low-temperature multi-effect desalination is better than the reverse osmosis desalination and the reverse osmosis desalination with one-level reverse osmosis is considerable with low-temperature multi-effect desalination.In addition,two kinds of desalination programs in Ba Jiao plant are analyzed and finally the desalination program is determined.
