Moving the feed position of the catalytic stabilizer tower upward increases the number of () trays, which is beneficial for controlling (), but not for controlling (). Distillation section: stabilizing the saturated vapor pressure of gasoline; carbon pentane content in liquefied gas

Raising the feed position of the catalytic stabilizer tower, as well as increasing the number of trays in the stripping section, helps to control the vapor pressure of gasoline; however, it hinders the control of the C5 content in the liquid hydrocarbons.
In the stripping section, steam pressure is controlled, which is not conducive to controlling the pentane content in the liquefied gas.

An increase in the number of trays in the stripping section facilitates the control of gasoline vapor pressure, but hinders the control of the C5 content in liquefied gas
An increase in the number of plates in the stripping section helps to control the vapor pressure of gasoline, but hinders the control of the C5 content in liquid hydrocarbons
An increase in the number of trays in the lower section (distillation section) is beneficial for controlling the saturated vapor pressure of gasoline, but it is not conducive to controlling C5 in LPG.
