What is the operating pressure of the decompression tower and the stabilization tower?
Thread Content
I would like to ask what the operating pressure is for the parsing tower and the stabilizing tower
This depends on the capacity of your air compressor; it’s generally around 1.0 to 1.3 MPa.
What kind of device are you? Catalysis or coking? Generally, the value for the reaction tower ranges from 1.1 to 1.25, while that for the stabilization tower is between 0.9 and 1.1; these values need to be adjusted according to the operating plan, taking all factors into consideration
This needs to be determined based on the position
Between 0.9-1.1MPA I guess
There’s no specific answer to this; I’m not familiar with catalysis. In the case of coking, adjustments need to be made based on the properties of the dry gas and liquefied gas
Consider the cooling capacity at the top of the stabilizer and the capacity of the compressor. In particular, if the cooling capacity at the top of the stabilizer is sufficient, the operating pressure can be kept lower
For distillation columns, low pressure and high temperature are favorable for the distillation of C1 and C2. However, in actual production, the stripping tower is connected to the absorption tower, and the absorption and stripping effects must be considered together to select an appropriate pressure. The pressure control of the stabilizer tower must ensure that the vapor pressure of gasoline is within acceptable limits, while also preventing the C5 content in the liquid hydrocarbons from exceeding specified levels. Taking into account both product quality and energy consumption, it is appropriate to control the pressure of the absorption and stabilization system at 1.0~1.3 MPa during operation.
Generally, 1.0-1.2 is sufficient.

Due to differences in plant design, the operating pressures set for the two towers vary slightly; the separation tower and the stabilization tower typically operate at 1.0 MPa to 1.2 MPa
