| Abstract: | The extension retrofit of a propane deasphalting unit was simply presented. The result shows that the design requirements of a 180kt/a unit could be satisfied by using the high efficient extraction tower with FG Ⅱ + type regular packing without changing the diameter and height of the tower, the recovering rate of the deasphalting oil could be increased by about 7%. The operation of the extraction tower was stable, its operating elasticity was wide after the retrofit, and the retrofit target was reached. |
