Prelimiary Investigation Desalting of Geothermal Brines in the Imperial Valley of California


Book Description

The Imperial Valley Project is an applied research program to provide geologic, hydrologic, engineering, and economic information necessary for development of the geothermal resources of the delta of the lower Colorado River. It is suggested that a desalting pilot plant be associated with the project to develop an economic desalting process if 2 to 3% geothermal brine is produced. The process will be unconventional in that waste heat must be rejected to atmosphere in wet or dry cooling towers. The presence of large amounts of CO/sub 2/, H2S, and silica will require gas removal and silicascale control equipment. The plant would process up to 75,000 gallons of brine per day. (MCW).

OUT Success Stories


Book Description

DOE research helped develop the large, untapped geothermal resource beneath the Salton Sea in California's Imperial Valley. The very hot brines under high pressure make them excellent for electric power production. The brines are very corrosive and contain high concentrations of dissolved silica. DOE worked with San Diego Gas and Electric Company to find a solution to the silica-scaling problem. This innovative brine treatment eliminated scaling and made possible the development of the Salton Sea geothermal resource.




Progress Report Processing of Hypersaline Brine


Book Description

There are several known areas in the Imperial Valley of California where geothermal brines having probable commercial value exist. The main ones being considered today are the Niland area, Heber area, East Mesa, and North Brawley. The bottom-hole temperatures and salinity of the brines from the different areas show wide variation. The highest bottom-hole temperatures and highest salinity so far known are found in the Niland area. This area covers the largest areas of proven ground so far known in this vicinity. This is the area considered as producing the Hypersaline Brines.
