Factors affecting the separation efficiency of the separation tower
Thread Content
What will happen if the liquefied gas content in the feed to the stripping tower increases while the temperature at the bottom of the stripping tower remains unchanged?
As the gas-phase load increases, the reflux flow rises; pay attention to pressure changes
It is best to use software simulations (PROII or ASPEN) to determine the differences under current conditions and those under changed operating conditions; otherwise, only qualitative information is available, which is not sufficient to guide production. Casual discussions are acceptable though
The gas phase load in the upper part of the feed section of the stabilizer increases; if control is necessary, the reflux rate should be adjusted to maintain balance between the gas and liquid phase loads. Additionally, with the bottom temperature remaining constant, the top temperature and pressure will change, and the change in top pressure is significant (given a fixed cooling load at the top, in fact, water cooling at the top is usually excessive)
As the feed rate increases, both the top and bottom loads of the tower increase； If the temperature at the bottom of the tower remains unchanged, the efficiency of separation will decrease; the gas load in the top of the tower increases, and accordingly, the liquid reflux flow rate should be increased appropriately as a adjustment
