Abstract: THE INVENTION RELATES TO A METHOD AND APPARATUS FOR THE CONTINUOUS REMOVAL OF HIGHER BOILING POINT CONSTITUENTS FROM A PROCESS GAS STREAM CONTAINING SUCH CONSTITUENTS. IT RELATES PARTICULARLY TO A PROCESS FOR THE PURIFICATION OR ENRICHMENT OF A GAS BY CRYOGENIC CONDENSATION OF THE HIGHER BOILING POINT CONSTITUENTS FROM THE GAS STREAM, WHICH CONDENSATE IS TRANSFERRED TO A MINOR STREAM OF THE PURIFIED GAS AT SUBSTANTIALLY ATMOSPHERIC PRESSURE IN A PURGING STEP. THE REGRIGERATION NECESSARY TO DRIVE THE CRYOGENIC SYSTEM IS FURNISHED BY A MODERATE EXPANSION OF THE PURIFIED GAS AND A FURTHER EXPANSION OF THE PURGE GAS. THE REFRIGERATION POTENTIAL, REPRESENTED BY THE LATENT HEAT OF THE CONDENSATE, IS CONSERVED BY A RECYCLE STREAM OF THE PURIFIED GAS.
