Automatic Steam Gathering Reduces Emissions at The Geysers

Serial Information: Civil Engineering—ASCE, 1980, Vol. 50, Issue 6, Pg. 78-79

Document Type: Feature article


At the site of The Geysers, America's only geothermal power plant and the largest such plant in the world, the first completely computerized steam gathering system has been installed. The project minimizes hydrogen sulfide emissions to within the limits allowed by the government by the use of the Stretford Process. That process removes sulfur compounds by means of a surface condenser after the stream leaves the turbine. Close monitoring of loads on the steam gathering system allows operators to use the steam more efficiently. The system reduces the number of required operating personnel, continuously collects data on well production, and allows operators to respond quickly to turbine problems.
