An open loop gas recovery and recirculation system has been developed for the INORPC system. The gas mixture coming from RPC exhaust is first desiccated by passing through molecular sieve(3 A˚ +4 A˚ ). Subsequent scrubbing over basic active alumina removes toxic and acidic contaminants. The Isobutane and Freon are then separated by diffusion and liquefied by fractional condensation by cooling upto-26 °C. A Residual Gas Analyser (RGA) is being used in the loop to study the performance of the Recirculation system. The results of the RGA analysis will be discussed.
