Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A CONTINUOUS METHOD FOR SEPARATING WATER AND READILY LIQUEFIABLE HYDROCARBONS FROM GASEOUS STREAMS UNDER PRESSURE IN A GAS SEPARATING SYSTEM WHICH COMPRISES FIRST FORMING HYDROCARBON HYDRATES IN SAID STREAM BY COOLING BY HEAT EXCHANGE MEANS, THEREAFTER SEPARATING LIQUIDS FROM THE GASEOUS STREAM, FURTHER COOLING THE GASEOUS STREAM BY EXPANSION, AGAIN SEPARATING LIQUIDS FROM THE GASEOUS STREAM, AND RECURRENTLY INTERRUPTING SAID FIRST COOLING TO CAUSE THE SYSTEM TO BE FLUSHED OF HYDRATE FORMATION BY THE INCOMING GASEOUS STREAM.
Claim 2
Dependent Claim
77 words

Claim 3
Dependent Claim
73 words
A HIGH PRESSURE, LOW TEMPERATURE GAS SEPARATOR WHICH COMPRISES MEANS TO COOL AN INCOMING FLUID STREAM BY HEAT EXCHANGE, MEANS TO SEPARATE A LIQUID PORTION OF SAID COOLED STREAM, MEANS TO THEREAFTER EXPAND SAID FLUID STREAM, AND MEANS TO SEPARATE ANY LIQUID FORMED AFTER THE EXPANSION OF SAID STREAM, AND AUTOMATIC, TEMPERATURE INDEPENDENT MEANS TO RECURRENTLY INTERRUPT SAID HEAT EXCHANGE COLING MEANS WHEREBY SAID INCOMING FLUID STREAM WILL RECURRENTLY WARM UP SAID SEPARATOR.
Claim 4
Dependent Claim
73 words
A HIGH PRESSURE, LOW TEMPERATURE GAS SEPARATOR WHICH COMPRISES MEANS TO COOL AN INCOMING FLUID STREAM BY HEAT EXCHANGE, MEANS TO SEPARATE A LIQUID PORTION OF SAID COOLED STREAM, MEANS TO THEREAFTER EXPAND SAID FLUID STREAM, AND MEANS TO SEPARATE ANY LIQUID FORMED AFTER THE EXPANSION OF SAID STREAM, AND AUTOMATIC, TEMPERATURE INDEPENDENT MEANS TO RECURRENTLY INTERRUPT SAID HEAT EXCHANGE COLING MEANS WHEREBY SAID INCOMING FLUID STREAM WILL RECURRENTLY WARM UP SAID SEPARATOR.
