| Abstract: | It was proved that the solvent waste heat can be utilized to heat the inter-reboiler which wasincreased in the pre-distillation tower, the seperation at top and bottom of the tower can be satisfied with the solventwaste heat; The steam used for heating the pre-distillation tower can be decreased, and the circulation water forsolvent cooler can also be saved by this process. |
