Liquified petroleum gas production

Claim 1

A PROCESS FOR THE PRODUCTION OF DEHYDRATED LIQUIFIED PERTOLEUM GAS WHICH COMPRISES (1) FRACTIONATING A PETROLEUM DISTILLATE CONTAINING LPG HYDROCARBONS TO OBTAIN A FRACTION CONSISTING ESSENTIALLY OF FUEL GAS, LPG HYDROCARBON GAS AND WATER VAPOR, (2) COOLING SAID FRACTION TO CONDENSE THE LPG HYDROCARBON AND WATER, (3) DECANTING LIQUID WATER PHASE FROM LIQUID LPG HYDROCARBON PHASE CONTAINING DISSOLVED WATER, (4) WITHDRAWING A STREAM OF SAID LIQUID LPG HYDROCARBON PHASE FROM SAID DECANTING ZONE, APPLYING THERETO A PRESSURE SUFFICIENT TO PERMIT THE CYCLING OF SAID STREAM AS REFLUX TO SAID FRACTIONATING ZONE, (5) CYCLING A PORTION OF SAID STREAM TO SAID FRACTIONATING ZONE AS REFLUX, (6) PASSING ANOTHER PORTION OF SAID STREAM TO A COOLER WHEREIN THE TEMPERATURE OF SIAD STREAM TO A COOLER WHEREIN THE TEMPERASOME OF THE WATER IS REDUCED SUFFICIENTLY TO PRECIPITATE PRECIPATED WATER FROM LIQUID LPG HYDROCARBON OF REDUCED WATER CONTENT, (8) PASSING A PORTION OF THE REDUCED WATER CONTENT LIQUID LPG HYDROCARBON OF STEP (7) THROUGH A SOLID ADSORBENT MATERIAL TO OBTAIN A LIQUID LPG HYDROCARBON STREAM OF ESSENTIALLY NO WATER CONTENT AND CONTINUING SAID DEHYDRATION UNTIL SAID ADSORBENT HAS BECOME SPENT, (9) HEATING ANOTHER PORTION OF REDUCE WATER CONTENT LIQUID LPG HYDROCARBON OF STEP (7) TO OBTAIN A GAS HAVING A TEMPERATURE SUITABLE FOR DESORBING WATER FROM SAID SPENT ADSORBENT AND HAVING A PRESSURE HIGHER THAN THAT EXISTING IN SAID FRACTION OF STEP (1) AND PASSING SAID GAS THROUGH SPENT ADSORBENT UNTIL SAID ADSORBENT IS REVIVIFIED, AND (10) PASSING THE MIXTURE OF GAS AND VAPOR OF DESORBED WATER INTO THE FRACTION OF STEP (1).
