Interest in utilizing the geothermal resources of the Imperial Valley in California for the generation of electricity has accelerated rapidly in recent years. One resource in particular, The Salton Sea Geothermal Field, is attractive because of its high temperature and size. Recent estimates (1) of its potential for electrical power generation range between 1300 and 8700 MW per year (over a 20-year period). The fluid of this resource, however, is a highly-corrosive, high-salinity brine that contains several constituents that form deposits of scale on plant structures as the brine is cooled. Economical utilization of Salton Sea Geothermal Field will require techniques for controlling scaling and corrosion at acceptable levels.
