Effect of benzene removal tower pressure on crude benzene yield

Pressure definitely has an impact! We keep it between 8 and 12 KP
It has an impact on steam usage; theoretically, the effects on both the quality of crude benzene and the quality of oil-free product can be addressed by adjusting the amount of steam used
Of course it has an impact. The removal of benzene is achieved by reducing the vapor pressure of benzene at the top of the benzene removal tower; the lower the vapor pressure of benzene at the top, the easier it is for benzene to be evaporated and separated from the oil-rich mixture. Therefore, the pressure at the top of the benzene removal tower is very important. We usually keep it at 12---16 Kpa.
We only have 2 kPa here; how do others adjust the pressure at the top of the tower?
