High purity CO2 and BTEX recovery

A method of producing BTEX fuel from a hydrocarbon gas mixture comprising the steps of:

• removing water from the hydrocarbon gas mixture
• separating the hydrocarbon gas mixture into vapor and liquid phases;
• heating the liquid phase to approximately 80° F. and separating the heated liquid phase in a three-phase high pressure tank into vapor, water, and liquid hydrocarbon phases, the liquid hydrocarbon phase including the BTEX hydrocarbons;
• and
• drawing the liquid hydrocarbon phase including the BTEX hydrocarbons off of the water phase in the high pressure tank;
• and
• stabilizing the liquid hydrocarbon phase from the high pressure tank in a two phase tank at a pressure lower than the pressure in the high pressure tank, thereby further separating vapor from the liquid hydrocarbon phase to produce BTEX fuel therefrom.
