Claim:
1. A process for treating at least one gas stream comprising hydrogen, methane and C 2 + hydrocarbons, said process comprising: (a) sending said gas stream through a first pressure swing adsorption unit to produce a first purified stream and a second purified stream, wherein said first purified gas stream comprises more than 80% of the hydrogen from said gas stream and at least 60% of said methane from said at least one gas stream and wherein said second purified gas stream comprises at least 90% of said C (b) sending said first purified gas stream to a second pressure swing adsorption unit, wherein the second pressure swing adsorption unit is in series with the first pressure swing adsorption unit to produce a hydrogen product stream comprising at least 80% hydrogen and a fuel gas stream comprising at least 90% of said methane from said gas stream; c) sending a stripper gas to a gas plant that produces a plurality of streams including a lean gas stream and combining said lean gas stream with said at least one gas stream; and d) sending C
