Hello experts, I am now involved in a project to design a distillation column for PF5 generator. This project is a scale up of existing plant. Existing design of distillation column is: Bottom part of the column is a reactor and there is a re-circulation pump. There is only 1 outlet from the...

Hello experts!! Is it possible to obtain overall heat transfer coefficient value (roughly) without experiment for a reactor with cooling jacket? My approach to estimate U value by designing shell and tube heat exchanger using process simulator but the value was quite high than our expectation...

Dear experts, I am still in the learning phase. Bear with me. (My main task is process simulation but slowly trying to develop myself into a process engineer) While preparing a datasheet for pressure vessels, what would be sound engineering practices to specify the design pressure and...

Can anyone suggest a vendor that manufactures a 2 KW capacity turbo-expander? It is for laboratory purposes. The least I found was 25 KW by Turbogaz.

I am looking for a pump vendor which meets my design specification: Process fluid: Liquid CO2 Temp: -50oC suction prsesure: 7 barg discharge pressure: 70 barg volumetric flowrate (at T and P): 60 L/hr. I tried to find local vendors in South Korea but no luck with this low temperature and small...

Dear experts, This query is based on simulation results (aspen hysys). What I thought was scrubber or column bottom pressure would be at bubble point which corresponds to bubble point pressure. However, the vapor pressure at the scrubber bottom temperature (with the same composition) is...

Hello, one of our clients wants to start a project for 2-propanol separation. I have developed a flowsheet for the process (I have attached the flowsheet). The product purity is very important as it is to be used in semi-conductor (product purity=99.99 wt%). I realized from simulation (dynamic)...

Hello everyone, I am currently working on a project for 2-propanol separation. Feed is multicomponent consisting of methanol, acetone, diisopropyl ether, 2-propanol (97 wt%)and water. We are using two-column distillation process to obtain 99.99 wt% IPA. Now my problem is choosing the right...

Hello everyone, we are supposed to design (revamping case) a process for the separation of polymer mixtures. Two of the components (out of four) have the same boiling point. The only difference between the two components is the acentric factor. The current process is operated successfully...
