FIELD: process engineering.
SUBSTANCE: invention relates to cleaning and separation of helium-bearing fuel gases including natural and associated oil gases. Proposed method comprises creating the flow of dried green gas cleaned of carbon dioxide and sulfuric compounds, cryogenic processing with removal and derivation of methane product fractions and heavy hydrocarbon fractions, and processing aimed at helium extraction and helium concentrate flow production. Processing with extraction of helium till cryogenic processing is carried out by diaphragm gas separation with feed of compressed green gas to high-pressure inlet of the primary diaphragm gas separation unit and forcing of said green gas along diaphragm helium-permeable surface. Gas flow penetrated through diaphragm is discharged as low-pressure helium concentrate while high-pressure gas not penetrated the diaphragm is fed to cryogenic processing.
EFFECT: lower costs, higher yield, simplified process.
