Tower pressure drop design
Thread Content
How to design the pressure drop of the tower? Can you use aspen to calculate the pressure drop of the tower?
The pressure drop in aspen is generally set by the calculator. The software only simulates based on the value you give. It seems that it cannot calculate the pressure drop of the tower. The pressure drop of the tower is related to the type of tower and tower internals used. Generally speaking, for vacuum towers, the pressure drop should be smaller.
Can you use aspen to calculate the pressure drop of the tower? Yes, enter the data, TRAY/PACK RATING>Design/Pdrop>Update section pressure profile and the result is in PROFILE
The determination of pressure drop depends more on experience and manuals. Usually the data calculated by Aspen is slightly smaller and should be appropriately amplified.
I generally don't use aspen to find pressure drop. Still rely on experience and manual calculations. Sometimes the FRI Tray Rational software of the American Distillation Company is used for calculations, but it is only a reference and cannot be relied upon too much.
