Where is the appropriate location for the side line extraction in the middle of the distillation tower? ? ?
Thread Content
If there is a distillation tower that requires extraction from the middle side line, consider the location of the extraction outlet.: (1) The extraction outlet is opened in the middle of the liquid pipe, as shown in Figure 1 below. (2) The extraction outlet is opened in the groove of the liquid receiving plate, as shown in Figure 2 below. Please tell me what you think is reasonable, or how the opening should be more appropriate. Personally, I prefer Figure 2, because the liquid produced in Figure 1 is easily mixed with gas phase, which may have an impact on the production flow rate.
The extraction must be done by setting up a liquid collecting tank in the tower, which is definitely not possible as shown in Figure 1. As for the number of trays, it depends on what you are extracting. For example, the benzene tower is on the fifth tray.

You can calculate which tray to put on it, no problem. As for the specific setting location, I feel it is more appropriate to place it in the tray liquid collecting tank.
And you also need to consider whether the tower pressure requires a side extraction pump, and whether the other end of the feed is allowed to carry liquid with air. If a side extraction pump is needed, a liquid collecting tank must be set up, and the buffer amount must be calculated.
The side mining line first comes out with a flow meter to measure the liquid flow, then enters the heat exchanger to cool down and enters the buffer tank, and then pumps it to the product tank.
Set up a oil collection tank otherwise the liquid extraction will be blocked
