Styrene Process with Aspen Plus 1/9 - mass balances

Simulation of the classical Ethylbenzene-Styrene process.
This workshop is meant to be a walkthrough of the Aspen Plus functions from beginner (parts 1-3) to intermediate level (parts 4-9).

thanks for the lecture,

[@tuahalomoan6905]

Hello.. Thank you for the tutorial. I have been follow all the first step. but in the first step, when I have done specify the second reactor then go to the control panel, the run button is doesn't comes out. so I cannot run in the control pannel. any suggest? thank you

Try use the 'next' button instead, so the interface will prompt with the "missing input" screen. This bug is often the consequence of some mis-connected stream. Let me know.

Hello Antonio, SORRY for the irrelevant question. I am modelling the methane reforming process coupled with chemical looping, I am really curious and want to ask a question. Suppose we have an absorber column, and we have a total 4 streams for the absorber as given below. Stream No 1: As input stream from bottom containing CO+ H2 Stream No 2: As input stream or recycle stream for the purified MEA from stripper column. Stream No 3: As output stream, containing large quantities of Hydrogen and minute quantities of CO2. Stream No 4: As output stream, with mixture of CO2 absorbed MEA. Now the question is how many streams are necessary to define out of these four streams, either two streams or three? OR we can only define one input stream in order to run the model. Is there any general rule to identify this?

i wish the earlier onces was in English

Sorry, I will do my best from now on. Is there something specific that you need but couldn't understand?
