I’m a complete beginner; I would like to ask the experts about simulation problems related to the absorption of HCl in a packing tower
Thread Content
The process is very simple: the packing absorbs HCl. The packed tower I have illustrated doesn’t have any trays; it consists of two layers of BX structured packing, along with a corrugated plate mist eliminator at the top. However, there was an issue with the choice of feed streams – logically, the gas feed should be at the bottom while the wash water feed should be at the top. But an error occurred, and I hope the expert from Haichuan can provide some guidance. . . . . Thank you:handshake:handshake:handshake
In this type of unit without a reboiler or condenser, feed must be provided at both the top and the bottom. Using “tray” as the setting for the bottom part is incorrect; that doesn’t mean feed is applied at the bottom. You can use “on-stage” or vapor feed, and it seems that setting the number of trays by 1 (“tray”) is also an option
The gas-phase feed is at 3+1=4 trays
Use the English version – what’s the difference between on stage and above stage?
