Cost of meeting geothermal hydrogen sulfide emission regulations. [DOW, EIC, Stretford, and iron catalyst processes]
H{sub 2}S emission abatement processes considered feasible for control of airborne emissions included two upstream and two downstream treatment techniques. From literature describing the technical aspects of the processes, individual treatment cost functions were developed. These functions were then used to estimate the range of costs that may be encountered when controlling H{sub 2}S emissions to meet given standards. Treatment costs include estimates of certain fixed charges and overheads that normally apply to long lived capital investment projects of similar nature. Continuing experience with control technology for H{sub 2}S abatement indicates process application may have a significant impact on the total cost of geothermal electricity at sites with H{sub 2}S concentrations in excess of 50 ppM{sub w}. Approximately four sites of the 38 USGS high temperature hydrothermal systems fall into this category. At Baca, New Mexico the cost of controlling H{sub 2}S emissions was estimated to be 5.5 mills per kWh. Calculations were based on a 50 MWe flashed steam plant using the Stretford-Peroxide combination of processes to achieve 99% abatement.
