Single Flash Geothermal Plant
For those geothermal resources with a temperature generally above 190ºC, a single-flash type of plant is often the best economic choice. Higher temperature reservoirs will typically produce both water and steam under natural pressure. This two-phase flow is usually directed to a separator that allows the steam fraction to be piped to the plant and the water fraction to be piped back into the reservoir via injection ...

Double flash geothermal power plants
Resource conditions may allow consideration of a dual-flash plant. Substantially similar to a single-flash plant, a dual-flash plant is capable of utilizing more of the total flow from the reservoir than a single-flash plant. This increase in resource utilization comes with a corresponding increase in plant complexity and ...

Combined Cycle Geothermal Power Plant
Resource conditions and project economics may allow a plant configuration that combines single-flash and binary technologies. In this arrangement, two-phase flow from the resource is directed to a separator in the same manner assingle-flash, but rather than injecting the separated brine, the brine is directed to binary equipment. There may also be other combined cycle arrangements, such as using a back-pressure steam turbine and binary equipment. In this ...

Binary - Power Plant
Choice of a particular power plant design is based on a number of factors, with resource temperature being one of the most important considerations. In general, low to moderate temperature resources lend themselves to a binary ...
