SYSTEMS AND METHODS FOR PRODUCING DIMETHYL SULFIDE FROM SOUR GAS

摘要

Dimethyl sulfide is produced from sour gas. The dimethyl sulfide is utilized in an oil recovery formulation introduced into a petroleum-bearing formation to enhance recovery of petroleum from the formation.

主权项

1. A method comprising:
separating methane and separating hydrogen sulfide from a sour gas comprised of methane and hydrogen sulfide; producing carbon monoxide and hydrogen from at least a portion of the separated methane; producing methanol from at least a portion of the produced carbon monoxide and at least a portion of the produced hydrogen; producing a dimethyl sulfide from at least a portion of the produced methanol and at least a portion of the separated hydrogen sulfide; producing an oil recovery formulation that comprises at least 75 mol % dimethyl sulfide from at least a portion of the produced dimethyl sulfide; introducing the oil recovery formulation into a petroleum-bearing formation comprising petroleum; contacting the oil recovery formulation with petroleum in the petroleum-bearing formation; and subsequent to contacting the oil recovery formulation with petroleum in the petroleum-bearing formation, producing a fluid from the petroleum-bearing formation, wherein the produced fluid comprises at least a portion of the petroleum from the petroleum-bearing formation.
