Cryogenic gas processing system

Abstract

Abstract EFFICIENT USE OF THE REFRIGERATION CAPACITY OF A CRYOGENIC SUPPLY, WHILE ALSO MAINTAINING TEMPERATURE CONTROL OF A PROCESS CONTROL CRYOGEN DURING PASSAGE OF A GAS MIXTURE IN COMMUNICATION WITH THE PROCESS CONTROL CRYOGEN, IS ACHIEVED BY EMPLOYMENT OF A BYPASS HEAT EXCHANGE BETWEEN THE CRYOGEN SUPPLY AND A PORTION OF THE GAS MIXTURE, WHICH IS ALSO PASSED THROUGH A PRINCIPAL COUNTERFLOW HEAT EXCHANGER. ISOTHREMAL HEAT EXCHANGERS USING THE CRYOGENIC SUPPLY AND THE PROCESSED GAS MIXTURES MAY ALSO BE DISPOSED ALONG THE GAS FLOW PATH TO RESTRICT UNWANTED HEAT DISSIPATION AND TO ASSURE TEMPERATURE UNIFORMITY, SO AS TO OBTAIN EFFICIENT AND FULL RANGE COOLING OF THE GAS MIXTURE. COMPACT AND EFFICIENT HEAT EXCHANGE UNITS ARE DISCLOSED THAT MAY BE DISPOSED AT VARIOUS REGIONS ALONG THE GAS FLOW PATH FOR THESE PURPOSES.
