The Badger 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. The Badger study considers the Multi-Stage Flash (MSF) process,achieving a minimum overall pressure drop by an uninterrupted flow path of brine and product water through the evaporator flashing area. A performance ratio of 20pounds of product water per pound of steam yields a calculated water cost of $0.323per thousand gallons. The specified 30-year write-off at low interest rates allows comparatively high capital expenditures favoring titanium tubing for brine service which contributes to low maintenance and operating costs.
