PROCESS FOR NATURAL GAS PRODUCTION

Abstract:

Processes for natural gas production are described. The processes involve combining a membrane separation system and a thermal oxidizing system. The high and low hydrocarbon permeate streams from the membrane separation system are introduced into the thermal oxidizing system separately. The high hydrocarbon permeate stream provides fuel for the thermal oxidizing system, allowing a reduction in external fuel usage. The reduction in total fuel required yields increased gas production for the total plant. A solvent based acid gas removal system can optionally be included.
