Separation of helium from helium-containing methane realms fraction involves separating helium-containing methane-rich fraction, methane-enriched fraction and helium-enriched fraction, compressing, separating, purifying and cleaning

摘要

Separation of helium from pure fraction helium-containing methane realms fraction involves separating helium-containing methane-rich fraction, methane-enriched fraction and helium-enriched fraction, compressing helium-enriched fraction, separating compressed helium-enriched fraction with respect to partially-liquefied helium-depleted fraction and helium-rich fraction, performing adsorptive purification of helium-rich fraction, cleaning and removing pure helium fraction.
