Raw gas comes from gas wells. Then it starts by separating impurities, various non-methane hydrocarbons and water the condenstate is transferred to an oil refinery while the water becomes waste water. Next the acid gases are removed, the acid gets transferred to sulfur unit where the clause process takes place it is then put through tail gas treating. But back to the natural gas which is next dehydrated and has mercury removed and goes through nitrogen rejection then goes into NGL recovery, which includes the turbo-expander and demethanizer, it is then transferred to sweetening units which provides the outcomes of Ethane, Propane, Butanes, and Pentanes.
