The Fluor Corporation,Ltd. Conceptual Design of a 50MGD Desalination Plant.

摘要

The objective of this study is to produce a design which advances the technology of seawater conversion and to present the results in a form which can be used by any qualified individual or firm as the basis for an architectural-engineering design. Ground rules furnished by OSW specified that only the desalination section of a dual-purpose power-water plant be considered and that it be designed for a 30-year life. Process and structural design ideas are to be presented in terms of the complete plant concept. The complex is to be located on a typical California coastal site with capital and operating costs based on December, 1964,values. The plant described in this study employs the conventional multistage flash process. Four parallel evaporator trains were selected to best satisfy conditions of the study. Trains are arranged symmetrically with heat rejection sections centralized about a common pump pit to minimize costly piping runs between the various elements. All evaporator vessels are of concrete construction prestressed by post tensioning both longitudinally and circumferentially. Tubes are of 90-10 CuNi,performance ratio is 13.6lbs. water/lb. steam,water cost is $0.421per thousand gallons.
