Pressure difference between liquefied gas distillation tower and reflux tank
Thread Content
This is the liquefied gas and C5 separation tower; liquefied gas at the top of the tower, and C5 at the bottom. The tower pressure is 1.18 MPa, the reflux tank pressure is 1.05 MPa, and the pressure difference between the tower and the reflux tank is 140 KPa. The V3 valve opening is zero. What I want to ask is: what impact does an increase or decrease in pressure difference, while keeping the tower pressure constant, have on the equipment or the process? All fellow sailors are welcome to help answer questions.
I would like to ask: \"When the tower pressure remains constant while the pressure difference increases or decreases, how do you proceed?\"
Switch V1 valve; V2 controls tower pressure
If it is turned down, the flow rate will increase, causing vibration in the equipment. Is the analysis correct? Feel free to point out any mistakes.
If your cooler has two separate feed streams, there may be flow imbalances, resulting in large fluctuations in column pressure
