A process for recovering a processing liquid used in gas purification systems, e.g., to remove greenhouse gases, and containing water, the processing liquid, components having higher and lower boiling points than water and a component less volatile than the processing liquid, wherein the feed mixture is heated and introduced into a first separation zone, a portion of the water and the processing liquid being volatilized to produce a hot vapor stream comprising volatilized water and processing liquid. There is also produced a first residuum stream which contains some of the less volatile components and the unvolatilized portion of the water in the processing liquid. The hot vapor stream is introduced into the separation system forming part of a gas purification system. The majority of the energy in the hot vapor stream is recovered for use in the separation system forming part of the gas purification system. A substantially degassed processing liquid stream is recovered from the separation system forming part of the gas purification system. There is also recovered, from the separation system forming part of the gas purification system, the feed stream to the first separation zone.
