요약

Natural gas may be purified by removing C3+ hydrocarbons and CO2 in respective one or more separation units to yield conditioned gas lower in C3+ hydrocarbons and CO2 in comparison to the un-conditioned natural gas. Notably, the feed gas need not be subjected to joule-thomson expansion and molecular sieve dehydration performed by conventional processes. Rather, any water-rich reject stream from the separation unit(s) is dried downstream with a smaller compressor and smaller molecular sieve or gas separation membrane dehydration unit before it may be re-injected deep underground or deep under the sea bed.

대표청구항

1 . A method for purification of natural gas including methane, C02, water, and C3+ hydrocarbons, comprising the steps of:feeding a feed gas consisting of the natural gas to at least one separation unit;withdrawing a dry conditioned natural gas from the at least one separation unit that is enriched in methane in comparison to the feed gas and deficient in C3+ hydrocarbons, C02, and water in comparison to the feed gas;withdrawing one or more gaseous reject streams from the at least one separation unit, a totality of the one or more gaseous reject streams being enriched in deficient in C3+ hydrocarbons, water, and C02 in comparison to the feed gas and deficient in methane in comparison to the feed gas;compressing one of the gaseous reject streams so as to cause condensation of least some of the water contained therein produce a biphasic stream having liquid and gaseous phases; andfeeding the gaseous phase to a dehydration apparatus so as to remove at least some of the water contained therein and produce a stream of the dried gaseous phase.
