A PROCESS FOR REMOVING C3, C4 AND HIGHER ACETYLENES FROM A CRUDE ACETYLENE-CONTAINING GAS WHICH COMPRISES WASHING SAID GAS IN A FIRST SCRUBBING ZONE AT A TEMPERATURE BETWEEN ABOUT 0*C. AND -50*C. WITHIN A HYDROCARBON THAT IS LIQUID AT SAID TEMPERATURE FOR DISSOLVING ALL OF THE C4 AND HIGHER ACETYLENES AND A PORTION OF THE C3 ACETYLENES IN SAID HYDROCARBON, PYROLIZING ALL OF SAID HYDROCARBON USED TOGETHER WITH THE DISSOLVED C4 AND HIGHER ACETYLENES AND A PORTION OF C3 ACETYLENES, WASHING THE GAS FROM SAID FIRST SCRUBBING ZONE IN A SECOND SCRUBBING ZONE AT A TEMPERATURE ABOVE ABOUT -50*C. WITH A HYDROCARBON THAT IS LIQUID AT SAID TEMPERATURE FOR DISSOLVING THE RESIDUAL C3 ACETYLENES IN SAID HYDROCARBON, DEGASSING THE HYDROCARBON FROM SAID SECOND SCRUBBING ZONE TO RECOVER SAID RESIDUAL C3 ACETYLENES, AND RECYCLING RECOVERED C3 ACETYLENES TO THE CRUDE GAS ENTERING SAID FIRST SCRUBBING ZONE.
