Can pressure swing adsorption be simulated with Aspen?
Thread Content
I have been doing simulations for the conversion of coke oven gas into natural gas recently; the composition of the gas exiting the reactor is approximately 50% H2 and 45% CH4. The subsequent step involves using pressure swing adsorption to separate H2 from CH4. Has anyone done Aspen simulations for pressure swing adsorption?
It should be possible. This year, during the defense of final theses for third-year graduate students, there was someone in our school who worked on a topic related to this area, also using Aspen for simulations
The Aspen Adsorption module (known as Aspen Adsim before V7) is specifically designed to simulate adsorption processes.
If pressure swing adsorption is used with oil or other common absorbents, it is definitely possible. But I think it would be very difficult to simulate using solid pressure swing adsorption.
Adsorption theory is still at the empirical stage, and research on its mechanism is only in its initial phases； And any simulation software is based on theory; therefore, using such software for calculations is not very reliable and quite difficult. The theories behind unit operations such as distillation and absorption are essentially well-established, so the results obtained using simulation software are quite reliable. Always remember: simulation software is merely a tool; theory is what truly matters.
You can give Aspen Adsorption a try, but it seems there isn’t much information available about it, and not many people have discussed it either. Give it a shot
Which school are you from? Can I get relevant simulation materials? I want to learn it
Do you have any relevant materials? I want to learn it
Sir, why not mention the key points? I want some materials to study* it
Are you a graduate student in Professor Cui’s lab?
