Gasoline temperature at the top of the distillation column in petrochemical plants
Thread Content
I have a theoretical question: In petrochemical units such as those involved in catalysis and coking, the top of the distillation towers generally produces crude gasoline and gases, with the pressure maintained at around 0.1 MPA and the temperature at the top of the tower ranging from 110 to 130 degrees. Under these pressure and temperature conditions, is it possible to extract crude gasoline with a 90% boiling range from the top of the tower? Thank you, those who know, please share
It is feasible to extract crude gasoline covering 90% of the boiling range from the top of the distillation tower under a pressure of 0.1 MPa (i.e., approximately 1 atmosphere) and at a temperature of 110–130 degrees. This is mainly because under such operating conditions, most of the light components in the crude gasoline have been vaporized and may be discharged from the top of the tower, while the heavier components remain in liquid form. These conditions are suitable for separating light hydrocarbons from each other, while leaving behind the heavier oils. .
