Separation of wet pyrolysis gases by sorbent treating and fractionation

Claim 1

IN THE PROCESS OF SEPARATING WET HYDROCARBON PYROLYSIS GASES CONTAINING A MAJOR PROPORTION OF C1-C5 HYDROCARBONS INCLUDING C2-C4 OLEFINS AND A MINOR PROPORTION OF WATER VAPOR AND HIGH BOILING PSEUDO-GASOLINE COMPOUNDS THEREIN BY FRACTIONAL DISTILLATION THEREOF INTO LIGHT AND HEAVY FRACTIONS, INCLUDING THE STEPS OF COMPRESSING THE GASES TO SUPERATMOSPHERIC PRESSURE AND PASSING THE COMPRESSED GASES AS A FEED TO A DISTILLATION ZONE OPERATING WITH REFRIGERATED REFLUX, THE IMPROVEMENT WHICH COMPRESES: CONTACTING THE COMPRESSED FREED IN A GASEOUS STATE, AT TEMPERATURES ABOVE THOSE AT WHICH WATER VAPOR AND LIGHT HYDROCARBONS CONTAINED THEREIN FORM A HYDRATE, AND AT A PRESSURE OF ABOUT 50-550 P.S.I.G., WITH A LIQUID SORBENT CONSISTING ESSENTIALLY OF A POLYHYDRIC ALCOHOL CONTANING FROM 2 TO 6 CARBON ATOMS, THEREBY TO ABSORB A SUBSTANTIAL PORTION OF SAID WATER VAPOR AND PSEUDO-GASOLINE COM-
