Our plant currently has a liquefied gas aromatization unit; it has been modified to perform naphtha aromatization. However, during operation, the liquefied gas at the top of the stabilizer always contains C5 components in amounts of around 10%. Measures such as increasing the tower pressure, raising the temperature at the bottom of the stabilizer, and lowering the temperature at the top of the tower have not yielded very satisfactory results. I hope everyone can help analyze it and come up with some ideas! ! ! ! ! Thank you
In my personal opinion, two aspects should be considered: 1. Have the parameters been adjusted properly? If no adjustments have been made but they still haven’t been implemented, the results will naturally not be satisfactory ； 2. If we rule out the first reason I mentioned and consider the possibility related to the stabilizer tower, is the load on the stabilizer tower normal? Does the design of the stabilizer tower meet the production requirements? Is the tower tall enough? I analyze that, if we ignore the factor of operational load exceeding the design limit, the main issue is still an inadequate adjustment in the operations themselves
