Simulation of Short-cut Distillation Column (DSTWU) in Aspen Plus - Lecture # 52

Learn to simulate a short-cut distillation column (DSTWU) in Aspen Plus. The short-cut method is useful in providing initial estimates for the simulation of the rigorous distillation column, i.e., number of stages, feed-stage, actual reflux ratio, etc. The DSTWU makes use of the Win, Underwood, and Gilliand method.

Sir aapka distillation design and troubleshooting ka Full course available ho to ..I am interested..Aapke video very helpful hai....respect🙏🏻

In key component recoveries section asks for the mole fraction. However, you used mass fraction in this particular problem. Is that okay?

Reboiler= 65 kpa Condenser= 0.55 kpa Ethylbenezene,Styrene, Benzene, Toluene ko separate krna he 2 columns mein..... But error aa rha he bar bar

Dear Shagufta, please share the error. Thank you.

@@aspenchemchannel Separate ni kr rha.... Differentl results aa rhe hein Hysys ke short column Or aspen ke dstwu mein

In Aspen HYSYS, column is based on "Fenske-Underwood-Gilliland" method, while in Aspen Plus, DSTWU is based on "Winn-Underwood-Gilliland" method. So, you may expect different results.
