Abstract
Environmental restrictions on hydrogen sulfide gas emissions from geothermal operations in the Geysers steam field has led to the application of Stretford process for abatement of this gas. This process treats the noncondensable gases by taking the feed gas form the gas ejectors which are down stream from the turbine and condenser. The Venturi absorber, which ues a non volatile liquor, is designed to accomplish near total hydrogen sulfide removal. The origins and characteristics of potential streams from the Stretford process such as sir emissions, aqueous effluents, and solid wastes are described. The occupational hazards potentially associated with operation of Stretford units and toxicity and regulatory information about hazardous chemicals involved in this process is presented.
