A METHOD FOR OBTAINING EXTREMELY DRY GAS COMPRISING; COMPRESSING MOIST GAS IN A COMPRESSOR WHEREIN HEAT IS PRODUCED, COOLING THE COMPRESSED AIR, SEPARATING MOISTURE MECHANICALLY FROM SAID COMPRESSED GAS TO PRODUCE RELATIVELY DRY GAS, CONDUCTING SAID RELATIVELY DRY GAS UNDER PRESSURE THROUGH A MOISTURE ADSORBER IN WHICH MOISTURE IS SEPARATED FROM SAID RELATIVELY DRY COMPRESSED GAS TO PRODUCE EXTREMELY DRY GAS FOR USE BY A CONSUMER, CONDUCTING SAID EXTREMELY DRY GAS THROUGH A MAIN LINE TO A MAIN RECEPTACLE, STORING A PART OF SAID EXTREMELY DRY COMPRESSED GAS IN SAID MAIN RECEPTACLE, STORING A PREDETERMINED AMOUNT OF SAID COMPRESSED DRY GAS IN AN AUXLIARY RECEPTACLE BRANCHED OFF FROM THE MAIN LINE IN CONTINUOUS FLOW COMMUNICATION WITH SAID MOISTURE ADSORBER THROUGH A FLOW RESTRICTING DEVICE, REDUCING THE PRESSURE OF SAID PREDETERMINED AMOUNT OF SUCH STORED EXTREMELY DRY COMPRESSED GAS TO SUCH A LOW PRESSURE THAT SAID GAS IS CAPABLE OF CARRYING SEVERAL TIMES THE AMOUNT OF MOISTURE WHICH WOULD BE CARRIED BY THE COMPRESSED GAS ENTERING THE MOISTURE ADSORBER FROM THE COMPRESSOR, SUPPLYING SAID HEAT PRODUCED DURING COMPRESSION OF THE GAS IN THE COMPRESSOR TO SAID PREDETERMINED AMOUNT OF DRY GAS BY INDIRECT HEAT EXCHANGE IN SAID AUXILIARY RECEPTACLE, AND CONDUCTING SAID PREDETERMINED AMOUNT OF EXTREMELY DRY LOW PRESSURE AND HEATED GAS THROUGH SAID MOISTURE ADSORBER TO REGENERATE ITS MOISTURE ADSORBING ABILITY.
