Some issues with catalytic stabilization
Thread Content
The catalytically stabilized dehexaned oil entering the stabilizer tower has three inlets. Why are there three? Specifically, how to proceed based on the actual metrics. Please, dear sea friends, speak up more! It’s urgent!
Three inlets are provided to select the location of the feed inlet based on seasonal changes and feed temperature.

This is mainly due to the influence of temperature; in winter, when temperatures are low (the feed temperature is low), it is suitable for use at the upper feed inlet. Otherwise, it is the lower feed inlet.
To control the C5 content in liquefied gas, use the upper port in winter and the lower port in summer
The stabilizer tower is a complete distillation tower; the section above the feed inlet is the distillation section, while the section below it is the stripping section. The three feed inlets allow for selective feeding – different inlets are chosen depending on the seasonal climate and feed temperature, in order to ensure that the C5 content in the liquefied gas does not exceed specified levels and to maintain an appropriate vapor pressure for the stabilized gasoline.
