Abstract

Large capacity sea water desalination plants are usually multi-stage flash (MSF) distillation and to less extent multi-effect distillation (MED) plants. This paper presents a proposed arrangement to the already existing or planned single-purpose MSF desalination plant operated by the commonly used moderate pressure large boilers. The proposal suggests combining a thermo-vapor compression (TVC) distillation plant of multi-effect type with the existing (or planned) MSF plant. The TVC plant utilizes the high temperature and pressure steam supplied by the boiler to the conditions required by the MSF plant. The analysis presented in this paper indicates that the proposed system is superior from thermodynamics and initial cost view points, when compared with single MSF plants having a capacity of the combined system. The proposed system uses well proven and reliable type of equipment. A case study is given to appreciate the advantages of the proposed combination.
