Abstract
Solute gas-rich absorbing media formed in scrubbing a solute gas from an off-gas stream prior to discharge of the same are regenerated to solute gas-lean absorbing medium for recycle to the scrubbing operation. Hot solute gas-rich absorbing media is formed into one or more spray patterns of very small liquid droplets in a flowing purge steam stream in a chamber into which the solute gas is desorbed from the droplets. The droplets are coalesced to form a regenerated absorption medium, the solute gas-containing gas stream is cooled to condense out the steam and a pure solute gas stream is recovered. The operation may be effected in multiple stripping stages, which may utilize cocurrent flow of solute gas laden absorbing medium and purge steam within a single chamber or in multiple chambers. Multiple stripping steps may be effected within a single stripping stage.
