An apparatus and process for removal of heavy hydrocarbons (e.g., hydrocarbons that include five or more carbons such as pentane and hexane, etc.) from a feed (e.g., a feed comprised of methane and impurities) can include a scrub column and a stabilizer column arranged so that a portion of a first stream output from the stabilizer column is fed to the scrubber column to function as a reflux stream. Embodiments are provided in which the scrub column produces a stream comprising mostly methane (e.g. over 85 mole percent methane) and reduced heavy hydrocarbons so that reduced operational costs and improved operational flexibility can be realized in downstream natural gas liquefaction operations.
An apparatus for removal of heavy hydrocarbon impurities from a feed comprising methane gas and hydrocarbons having at least five carbon atoms, the apparatus comprising:
A process for treating a feed gas comprising methane and hydrocarbons having at least five carbon atoms, the process comprising:
