Conceptual Design and Cost Estimate of a Vapor Compression VTE/MSF Desalting Plant.

摘要

A conceptual design and cost estimate for an 8MGD prototype gas turbine powered vapor compression VTE/MSF (vertical tube evaporation/multistage flash) desalting plant were prepared. The process consists of a 34effect MSF, a 4effect VTE,and 593,200lb/hr vapor compressor powered by a commercial gas turbine exhausting through a heat recovery boiler. Total capital cost is estimated at $11,840,000,including the desalting plant and sea water intake. Water cost is estimated at $0.59per 1,000gallons,assuming a fuel cost of $0.30per million Btu.
