Catalytic stabilizer pressure
Thread Content
Without considering other factors, is it better for the separation of liquefied gas and gasoline if the control pressure in the stabilizer column of a catalytic cracking unit is higher or lower?
Without considering other factors, lower pressure should be better for separation.
A lower pressure facilitates separation, while a higher pressure promotes absorption.
Theoretically, reducing pressure is beneficial for separation, but in actual production, factors such as overall energy consumption, material consumption, and yield also need to be taken into account.
A lower pressure facilitates separation, while a higher pressure promotes absorption.
A lower pressure is beneficial for controlling the saturated vapor pressure of gasoline and ensuring stability, but it is not conducive to controlling the pentane content in liquefied gas; therefore, an appropriate pressure should be selected based on the quality requirements of the product
Adjust the pressure appropriately based on product quality
