State-of-the-art hydrogen sulfide control for geothermal energy systems: 1979

摘要: Existing state-of-the-art technologies for removal of hydrogen sulfide are discussed along with a comparative assessment their efficiencies, reliabilities and costs. Other related topics include the characteristics vapor-dominated liquid-dominated resources, energy conversion systems, sources emissions. It is indicated that upstream control preferred over downsteam primarily because inherently controls all downstream emissions including steam-stacking. Two processes resources appear promising; copper sulfate (EIC) process, steam converter (Coury) process combined an off-gas abatement system such as Stretford unit. For systems produce steam, where non-condensible gases scrubbed spent geothermal fluid appears to be promising. An efficient technology gas removal. In this case, partitioning in surface condenser will determine overall efficiency. Recommendations future environmental programs included.
