ABSTRACT:
Method and apparatus for regenerating physically acting organic scrubbing agents laden with sulfur dioxide and/or sulfur trioxide and eventually carbon dioxide in the course of a gas purification process. Equipment costs and energy losses are reduced by adding ammonia and, if necessary, water, to the laden scrubbing fluids and then separating the resultant ammonia sulfite and/or ammonia sulfate. Large differences in temperature between the scrubbing steps and the regenerating steps are not needed. A beneficial energy balance results.
