Absorbent to oil and gas ratio. Also, why does the temperature at the top of the stabilizer increase, causing the pressure at the top of the tower to keep dropping automatically?

1. What are the proportions of the catalytic stabilization gasoline supplementary absorbent and the crude vapor? Why, even after increasing the amount of absorbent to 80 tons, is there still carbon in the dry gas? 2. Why is the pressure at the top of the stabilization tower unstable? When the pressure reaches a certain level, the temperature keeps rising; shortly afterward, the pressure at the top of the tower drops again. Controlling pressure is crucial for liquefied gas, but since the pressure remains unstable, I hope some experts can provide guidance. Thank you
It is normal for the C3 content in the dry gas to be no more than 3% by volume; the liquid-to-gas ratio used in absorption is also adjusted based on this parameter. The pressure control of the stabilizer tower is not good; this requires analysis based on the specific control scheme. The quality of pressure control is closely related to the output of the tower top condenser. When the tower pressure is high and the heat transfer temperature difference is large, its output is high; conversely, its output is low. Therefore, it is necessary to identify the appropriate control point for the tower top pressure; otherwise, the phenomenon observed by the original poster will occur.
