Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
120 words
A LOW TEMPERATURE PROCESS FOR SEPARATING HYDROGEN SULFIDE FROM A NORMALLY GAESOUS HYDROCARBON WHICH PROCESS COMPRISES: COOLING A FEED GAS MIXTURE OF HYDROGEN SULFIDE AND AT EAST ONE NORMALLY GASEOUS HYDROCARBON, SAID FEED CONTAINING ABOUT 3-90 MOLE PERCENT OF HYDROGEN SULFIDE AND METHANNE AS THE MAJOR HYDROCARBON CONSTITUENT AND BEING ESSENTIALLY FREE OF WATER VAPOR, TO PRODUCE A SYSTEM CONSISTING OF GASEOUS HYDROCARBON AND SOLID HYDROGEN SULFIDE, SAID COOLING BENG CARRIED OUT TO A TEMPERATURE BETWEEN ABOUT -126*F. AND -200*F. AND AT A PRESSURE BETWEEN APPROXIMATELY 150 P.S.I.A. AND 450 P.S.I.A.; SUCH THAT SAID GAS-SOLIID SYSTEM IS FORMED; AND SEPARATING SAID GASEOUS HYDROCARBON PHASE WHICH HAS A HYDROGEN SULFIDE CONTENT LOWER THAN SAID FEED, FROM SAID SOLID HYDROGEN SULFIDE PHASE.
