Abstract
This invention relates to the separation of components from a gas mixture. Aspects of the invention relate to the separation of components, for example carbon dioxide (CO) and/or hydrogen sulphide (HS) from, for example, acid gas, for example natural gas, syngas or process gas although features of the invention may be applied to other source gases. Such a process is sometimes referred to as acid gas removal (AGR). In examples described herein, the source gas mixture contains COand/or HS in addition to other components and in some examples, the COand/or HS components of the gas are referred to as acid gas components. In examples of the invention, some or all of the acid gas component is removed using a solvent absorption method; some examples described use a chemical absorption system (for example including N-Methyl diethanolamine (MDEA)), and others use a physical solvent (for example based on methanol (MeOH)).
