The separation method is provided with: an absorption process for absorbing a desired component in a starting material gas into an absorption liquid by bringing said starting material gas and the absorption liquid into contact with each other inside an absorption unit; a regeneration process for releasing the desired component from the absorption liquid and regenerating the absorption liquid by heating the absorption liquid, which absorbed the desired component in the absorption process, in a regeneration unit; a post-regeneration separation process for separating the mixed fluid, which is the gas of the desired component released in the regeneration process and the regenerated absorption liquid, into the desired component gas and the absorption liquid; and a compression process for compressing the starting material gas prior to the absorption process and the regeneration process. In the regeneration process, said absorption liquid is heated by supplying the starting material gas compressed in the compression process to the regeneration unit and exchanging heat with the absorption liquid. In the absorption process, the starting material gas, which has been compressed by the compression process and has undergone heat exchange with the absorption liquid in the regeneration unit, is supplied to the absorption unit as starting material gas from which the desired component is to be absorbed into the absorption liquid. |
