Liquid flooding problem in the vapor phase propane removal column
Thread Content
At present, our company’s depropanization tower has experienced liquid flooding on multiple occasions. Could you experts please advise on how to resolve this issue?
Is the depropanization tower high-pressure or low-pressure? Foaming occurs: 1. Excessive reboiling volume; 2. Excessive liquid load; 3. Tray flooding; 4. If the materials at both the top and bottom of the tower are not up to standard, stabilize the tower pressure first, then reduce the load for adjustment. The specific solution depends on the particular operating parameters.
