Abstract: The invention relates to a method and apparatus for partially solidifying a methane comprising stream. The method comprises—providing a liquid methane comprising stream (30) at a first pressure (P1),—passing the liquid methane comprising stream (30) to a slush vessel (300) which is kept at a second pressure (P2), the second pressure (P2) being lower than the first pressure (P1), thereby cooling and at least partially solidifying the methane comprising stream (30) generating a methane comprising slush, and—collecting the methane comprising slush.

Abstract: A process for producing a purified gas stream from a feed gas stream comprising methane, carbon dioxide, and aromatic compounds selected from the group of benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene involves measuring respective amounts of carbon dioxide and aromatic compounds in the feed gas and providing the measured amounts to a controller. The feed gas stream and a stream of absorbing liquid comprising at least sulfolane, water and a secondary or tertiary amine is provided to an acid gas removal unit (AGRU) The controller adjusts one or more of composition, temperature, and flow rate of the stream of absorbing liquid to the AGRU to prevent amounts of aromatic compounds in an AGRU outlet stream from exceeding a predetermined maximum threshold.
