| Description/Abstract: | The pilot plant was configured to accomplish two objectives - first to evaluate the overall performance potential of direct contact powerplants and second to develop design criteria and parameters for full-scale direct contact plants. The pilot plant includes all of the process functions that would be incorporated in a full-scale plant. Incoming brine is treated to remove undissolved gases, pumped through the direct contact heat exchanger (DCHX), and then sent to a recovery system for removal of the dissolved working fluid. The chosen working fluid is isobutane (IC/sub 4/). The working fluid loop includes a radial inflow turbine with generator, condensers, hot-well reservoir, and a feed pump. A downwell pump was installed in the geothermal well to supply the plant with unflashed brine. (MHR) |
