Methods to reduce the pressure drop in the catalytic fractionation tower?

2009-02-17View Original

Thread Content

Which facility uses structured packing instead of trays in its distillation column in catalytic units, and what are the results?

When upgrading our unit’s original 200,000-ton small catalyst system, we replaced the fractionation tower’s packing, and its operation has been quite good. . . It means that one must always pay attention to the operations at the post and avoid rushing into the tower. . . Make sure the temperature at the top of the slurry doesn’t exceed 400, and ensure that the slurry doesn’t contain CAT as it moves towards the filler. . . Removing the catalyst from the filler has well-known disadvantages. . . . ^_^:lol

What is the pressure drop of your packed tower?

1. Replace with better trays. 2. Strictly control the flow back amount; excessive flow back is not allowed

The CEST from the Petroleum University that we are using now also works well. It turns out to be a composite inclined-hole tray.

Our factory uses the CTST high-efficiency tray towers from Hebei University of Technology; using a packed tower in place of trays does not affect the performance

1. Ensure proper reaction conditions and control the appropriate degree of reaction depth. 1. Appropriately reduce steam consumption. 2. Optimize the raw material combination. 3. Lower the system pressure as well as the pressure in subsequent units. 4. Select suitable equipment. 5. Control the reflux at an appropriate level
