Abstract:
1. A process for recovering a processing liquid from a feed mixture recovered from a gas purification system, said feed mixture comprising water, a processing liquid having at least one component having a higher boiling point than water, at least one component having a boiling point lower than water, and at least one component that is less volatile than said processing liquid comprising: recovering a stream of feed mixture from a separation system forming part of said gas purification system; heating said first stream of feed mixture; introducing said heated stream of feed mixture into a first separation zone wherein at least a portion of said water and a portion of the processing liquid is volatilized to produce a hot, vapor stream comprising volatilized water and said volatilized portion of said processing liquid, and a first residuum stream comprising at least some of said less volatile component and the unvolatilized portion of said water and said processing liquid; introducing said hot vapor stream back into said separation system forming part of said gas purification system; using heat from said hot vapor stream to heat said separation system forming part of the gas purification system; and recovering a substantially degassed processing liquid stream from said separation system forming part of said gas purification system.
