One of the gases which may be used in processes for fabrication of electro-optical materials including some solar cells is hydrogen selenide. This gas is included in the Environmental Protection Agency (EPA) list of toxic chemicals and requires care in use and treatment. No data were identified in the literature relating to scrubbing or other processes which have been used to control process effluents. This paper presents and discusses criteria for the development of an effective scrubbing system to handle hydrogen selenide based on current emission standards. Problems considered include the development of reactor and piping enclosure scrubbers as well as scrubbers for the effluent gas stream. Extrapolation of available data was used to predict performance of scrubbers based on typical designs. Data for the operation of a dual scrubbing system are presented which show that emissions of hydrogen selenide can be reduced well below threshold limit value (TLV) for a range of gas throughput rates. Future areas of research for improving cost effectiveness and capacity are discussed.
