A Recirculation Compressor for Hot Gases

摘要

A conventional sliding‐vane rotary compressor was modified for use in recirculating hot gases at design temperatures up to 425°C. The compressor has performed well at 350°C with gaseous streams of H2S, SO2, COS, CO2, N2, H2O, and Sx. Completely free of lubricants, only stainless steel and graphite surfaces are exposed to hot gases. The unit may be mounted within a heating medium for isothermal operation.
