Abstract (en)
[origin: CA3057248A1] The invention relates to a method (100, 200) for obtaining one or more olefins, wherein a gas mixture which contains hydrogen, methane, carbon monoxide, and hydrocarbons which boil at a higher temperature than methane is formed using an oxidative coupling of methane (10) and is subjected to a low temperature separation (1-5). The invention is characterized in that the low temperature separation (1-5) is carried out using a rectification column (2) with a first separation region (21), a second separation region (22) arranged above the first separation region (21), and a condenser evaporator (23), wherein the gas mixture is cooled, supplied to the first separation region (21) at least partly as a first separation input, and undergoes a first rectification process in the first separation region (21), thereby forming a first head gas and a first bottom liquid. A condensate which is returned to the first separation region is formed using a first part of the first head gas in the condenser evaporator (23), and a second separation input which is supplied to the second separation region (22) is formed using a second part of the head gas. The second separation input undergoes a second rectification process in the second separation region, thereby forming a second head gas and a second bottom liquid.
