Worthington Corporation 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 Worthington study covers the optimization of a multi-stage flash process designed with four parallel flow streams each employing 59heat recovery stages and 2heat rejection stages with a maximum brine temperature of 270F and a gain ratio of 19.76pounds of water per pound of steam. Total water cost is $0.361per thousand gallons. Vessels are of steel (ASTM A-285),tubes in the heat rejection section are 9-10 CuNi while those in the heat recovery sections are of aluminum brass. Tube sheets are 90-10 CuNi throughout.
