The higher the top temperature of the coking fractionation tower, the higher the top pressure; why is it that the higher the top temperature of the stabilizer, the lower the top pressure? How to explain it?

I earnestly ask the experts for their guidance. :handshake
1. With all other conditions in the fractionation tower unchanged, if the temperature rises first, the pressure will increase; if the pressure rises first, the temperature will drop. The same applies to the stabilizer tower. 2. Increase the amount of cold return flow, resulting in a decrease in temperature and an increase in pressure. The same principle applies. You can give it a try:lol
Pressure depends not only on the top temperature but also on factors such as the reflux ratio and composition, and these need to be considered comprehensively. The greater the load at the top of the tower, the higher the pressure
