Lockheed Missiles and Space Company 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. This study embodies a multi-flash system incorporating advanced design concepts. Plant is divided into four equal evaporator modules (12.5MGD each) each consisting of 3heat rejection and 27heat recovery stages. Each module a complete plant in itself,can be operated and controlled independently allowing planned outages for maintenance without shutting down the complete system. Innovations include a condenser tube bundle design which eliminates water boxes and expansion bellows and the use of a dropwise promoter to achieve a practically attainable dropwise condensation system. Water cost is $0.43per thousand gallons.
