USE OF GAS-SEPARATION MEMBRANES TO ENHANCE PRODUCTION IN FIELDS CONTAINING HIGH CONCENTRATIONS OF HYDROGEN SULFIDES
摘要
A method and system for processing produced fluids from a subterranean reservoir is disclosed. The system comprises: (a) a separator for separating produced fluids from a subterranean reservoir into associated gases, water and crude oil, (b) a membrane which receives at least a portion of the associated gases containing the hydrogen sulfide and separates the gas into a permeate stream enriched in hydrogen sulfide and carbon dioxide and a retentate stream depleted in hydrogen sulfide and carbon dioxide; (c) an amine unit for removing carbon dioxide and hydrogen sulfide from the retentate stream; and (d) a sour gas injection unit for injecting at the permeate stream in an underground formation.
