INTEGRATED COMPRESSOR/STRIPPER CONFIGURATIONS AND METHODS

摘要

Contemplated solvent regenerators include a flash drum in which lean solvent from the regenerator is flashed, and from which supplemental steam is recovered that is then fed back to the regenerator using a compressor, and most preferably a thermocompressor. Such devices have a substantially reduced net steam and energy requirement despite an increase in electrical energy demand, and further maintain a neutral water balance in the regenerator.
