Gas-phase kinetic energy factor of vertical sieve plate columns
Thread Content
What value is generally chosen for the gas kinetic energy factor in vertical sieve plate towers? I have designed a carbon removal and purification tower for propylene, with a design capacity of 70,000 standard cubic meters and a design pressure of 2.7 MPa； A total of 3 vertical sieve plates are designed, each equipped with 40 vertical sieve caps featuring holes with a diameter of 75 mm ； As a result, liquid carried over into the gas phase of the propylene carbon decarburization purification tower after 2000 hours of operation under the current design conditions. Could anyone please advise on what might be causing this? :handshake :handshake
The plate pore kinetic energy factor of vertical sieve plate towers is generally around 12. The vertical sieve tray tower is a technology that was abandoned in Japan during the 1960s and 1970s. We (the Institute of Chemical Engineering at Hebei University of Technology) have developed a new type of CTST tower based on it; its kinetic energy factor ranges from 6 to 35, the pressure drop across the trays is significantly reduced compared to that of vertical sieve tray towers, and the flow rate is also greatly increased. You can check our website: www.ctst.com.cn. The problem with your tower lies in the excessive kinetic energy factor of the plate holes, which causes vapor entrainment. If you have time, we can communicate; we can help you solve this problem. Email: ctstzqy@163.com Fax: 022-60202248 Phone: 022-26582246 Zhang Qianyu.
