Abstract
Abstract AN ARRANGEMENT FOR COMPRESSING GASES OF RELATIVELY LOW MOLECULAR WEIGHT CONSISTS IN CREATING A GAS-LIQUID EMULSION FROM THE GAS, THE EMULSION BEING FORMED BY INJECTION OF THE GAS INTO A LIQUID WHICH HAS PREVIOUSLY BEEN BROUGHT UP TO SPEED; THE EMULSION IS THEN SLOWED DOWN IN A DIFFUSER THEREBY UNDERGOING COMPRESSION, AND THE TWO PHASES-GAS AND LIQUID-ARE THEN SEPARATED. THE COMPRESSED GAS IS THEN PASSED TO ITS POINT OF UTILIZATION AND THE LIQUID IS THEN PUT THROUGH A PUMP WHERE IT REGAINS THE ENERGY WHICH IT HAD GIVEN UP TO THE GAS AND IS THEN RE-CYCLED WITH FRESH GAS TO BE EMULSIFIED AND COMPRESSED.
