TECHNOLOGY DEVELOPMENT FOR HIGH-SALINITY
Anders W. Lundberg, Lawrence Livermore Laboratory*
The accomplishments of the geothermal program at the Lawrence
Livermore Laboratory (LLL) during the last year have done much to bring
the large geothermal resources of Cali'fornia's Imperial Valley closer to
the point of commercial utilization. Successful testing of a
specially-designed turbine and verification of chemical methods for scale
control are the two main advances. However, they are both supported by a
strong base in support capabilities such as the analysis of two-phase
flow and in methods for conducting meaningful experiments in chemistry
and material science in real brine. In addition, studies are continuing
on other energy conversion concepts and detailed knowledge is being
developed for definition of a strategy for resource utilization. Current
activities also include efforts directed toward the remaining problems in
effluent treatment for disposal and to the refinement of our knowledge
regarding utilization of this large, known, but hostile geothermal
resource. (See Ref. 1).

The LLL program, funded by the U.S. Energy Research and Development
Administration (ERDA), can be divided into two distinct, but related,
I. Technology Development
This consists of an interdisciplinary approach to develop efficient,
reliable, brine-tolerant conversion systems uniquely designed for
utilization of the high temperature brines of the Salton Sea KGRA
(Known Geothermal Resource Area) where the dissolved mineral content
may be as high as 30% by weight. The emphasis is on development of
the Total Flow conversion system coupled with solution of the
problems of scale formation, corrosion, erosion, and brine and
II. Industrial Support
The purpose is to provide technical assistance to joint ERDA/industry
geothermal utilization programs to develop the Salton Sea KGRA.
Emphasis is on applying the expertise and results in the technology
development activity to provide technical support, as needed, to help
solve operational problems, and to carry out complementary applied
research to broaden opportunities for solution of potential
problems. Current involvement consists of working with the San Diego
Gas and Electric Co./ERDA project.
