Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
160 words
THE METHOD OF PRODUCING A STABILIZED HYDROCARBON LIQUID PRODUCT FROM THE HIGH PRESSURE HYDROCARBON FLUID STREAM INCLUDING, INJECTING A GAS HYDRATE INHIBITOR INTO THE FLUID STREAM FOR ABSORPTION OF WATER AND WATER VAPOR OF SAID STREAM, COOLING THE FLUID STREAM IN THE PRESENCE OF SAID HYDRATE INHIBITOR TO EFFECT CONDENSATION OF DESIRABLE LIQUEEFIABLE HYDROCARBON CONTENT OF THE FLUID STREAM WITHOUT FORMATION OF OBJECTIONABLE GAS HYDRATES, FLASHING THE HYDROCARBON CONDENSATE AND INHIBITOR MIXTURE INTO A STABILIZING ZONE OF LOWER PRESSURE, HEATING LIQID COLLECTING IN A LOWER PORTION OF THE STABILIZING ZONE, PASSING HOT VAPORS EVOLVED FROM SAID HEATING STEP INTO COUNTERFLOW CONTACT WITH THE HYDROCARBON CONDENSATE AND HYDRATE INHIBITOR MIXTURE WITHIN SAID STABILIZING ZONE TO FORM A STABILIZING LIQUID HYDROCARBON PRODUCT, SEPARATING THE HYDRATE INHIBITOR AFTER HEATING THEREOF BY THE HEAT OF SAID STABILIZING ZONE, REACTIVATING THE HYDRATE INHIBITOR BY REMIVING THE ADSORBED WATER AND WATER VAPOR, AND RECYCLING THE REACTIVATED HYDRATE INHIBITOR FOR RECONTACT WITH THE INFLUENT HYDROCARBON FLUID STREAM.
