Perform ASPEN simulation for the dimethyl ether distillation column
Thread Content
Recently, I’ve been getting errors while simulating dimethyl ether distillation. I’m asking the experts to provide me with a simulation for dimethyl ether distillation, so I can study it properly*study*. Material feed: 2117..53 kg/h, concentration 78% (molar ratio); output: 90%. I want to know the number of plates and the reflux ratio. I have ASPEN version 11.1.
This should be simple. What field of study? Dimethyl ether and what substance?
The theoretical number of theoretical plates, reflux ratio, and feed position can be determined using the Jianjie Tower DSTWU, and then a precise simulation can be carried out with RadFrac~
Dimethyl ether and water; I’m a beginner and make mistakes all the time. I don’t know where the problems lie
Case Study 1 of the course “Mathematical Models and Computer Simulation in Chemical Processes”: Methanol → Dimethyl Ether + Water – with detailed calculations included! It’s in the forum! Find it by yourself! If not! I’m sending it to you at Q272688821
The original poster might want to take a look at this post on dimethyl ether distillation: http://bbs.hcbbs.com/thread-532590-1-1.html; it contains examples of projects that have been carried out.
It should be okay, right? Any errors? Is it because the requirements cannot be met or because convergence does not occur? This system isn’t difficult; I’ve used ChemCAD to work on it and was able to meet the requirements
