ABSTRACT:
A process is disclosed for generating steam or electrical power from surplus heat transferred to the total bottoms liquid of a fractionation column. Preferably the reboiler of the column is supplied with more fuel than required in the operation of the column. A portion of the total bottoms liquid stream in excess of the net bottoms stream is diverted from the bottoms liquid destined for the reboiler. This diverted stream is used to vaporize a working fluid and this vapor is removed as a product or passed into the turbine of an electrical generator. The excess bottoms liquid is then split off and passed into the reboiler. The remainder of the bottoms liquid is the net bottoms stream and is used to preheat the working fluid. The process has the advantage of an exceptionally high thermal efficiency in terms of converting the surplus heat released in the reboiler into electricity.
