    Abstract: The invention relates to a process for the removal of CO2 from acid gas by cryogenic distillation performed in two steps. The feed mixture is first distilled at high pressure (at least 45 bar) in a first distillation column. The top product or a part thereof is then, after heating, subjected to a second distillation step at a lower pressure (lower than 45 bar). The top product of the second distillation step is methane of high purity (more than 99 mol.%). The bottom product of the second distillation step is recycled back to the first distillation column. The method according to the invention allows complete separation of methane also at higher level of acidic components, is economical and does not result in solid CO2 build-up, which is a common problem in cryogenic distillation.

    Abstract: Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a feed (100) is divided into two streams, wherein one stream is subjected to catalytic partial oxidation (CPO) (2) and the other stream is subjected to steam reforming (5) followed by a water gas shift reaction (51). The two streams are then recombined and can be used further in methanol synthesis (6). The recombined stream preferably has an R ratio, being a molar ratio (H 2 -C0 2 )/(CO+C0 2 ), in the range of 1.9 - 2.2 and preferably about 2. The invention further relates to a method for producing methanol from a hydrocarbon containing feed, wherein first synthesis gas is obtained according to the method of the invention, which synthesis gas is further used to produce methanol. Also, the invention relates to a method of adapting an existing methanol plant to the methanol production process of the invention.

    Abstract: Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a hydrocarbon containing feed, particularly natural gas (100), is subjected to catalytic partial oxidation (CPO) (2), followed by the water gas shift (WGS) (4) reaction of a part of the reformed feed. At least part of the shifted feed is then subjected to hydrogen purification, preferably by pressure swing adsorption (PSA) (5) to obtain pure hydrogen (108), which hydrogen is subsequently combined with the remaining parts of the feeds to yield synthesis gas particularly suitable for methanol synthesis. The recombined stream preferably has an R ratio, being the molar ratio (H 2 -C0 2 )/(CO+C0 2 ), in the range 1.9-2.2 and preferably about 2. The invention further relates to a method for producing methanol from a hydrocarbon containing feed, wherein first synthesis gas is obtained according to the method of the invention, which synthesis gas is further used to produce methanol.
