Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
40 words
A process for the removal of mercury from natural gas condensate comprising the steps of: passing said natural gas condensate over a catalyst in a reactor vessel and simultaneously passing a mixture of methane and hydrogen sulfide over said catalyst.
Claim 2
Dependent Claim
40 words
A process for the removal of mercury from natural gas condensate comprising the steps of: passing said natural gas condensate over a catalyst in a reactor vessel and simultaneously passing a mixture of methane and hydrogen sulfide over said catalyst.
Claim 3
Dependent Claim
29 words

Dependent Claim
19 words
A process according to claim 10 wherein said reactor vessel is maintained at a pressure of about 10-15 atmospheres.
Claim 15
Dependent Claim
19 words
A process according to claim 10 wherein said reactor vessel is maintained at a temperature of about 200-250° C.
Claim 16
Dependent Claim
29 words
A process according to claim 10 wherein the volume of said condensate passing over said catalyst every hour divided by the volume of said catalyst is below about 20.
