Suggestion — one question per week
Thread Content
Recently, while looking at Aspen’s materials, I always feel that there’s no one to discuss things with. So, following the model of other forums, we’ll have a “Question of the Week”. If you’re interested in this question, come and have a seat. Then write down your thoughts, or any confusions, etc. Over time, who knows, it might even become the preferred material for beginners learning *aspen at HaiChuan! ! I wonder if this method will work? Let’s all talk about it. . .
With support, last week at Aspen I only performed a tower separation; the conditions were optimized, and ProII was mainly used for that. Basically, there wasn’t much to gain.
I agree! Work on problems together and improve together; over time, the results will definitely be good!
Good idea!! Give me a platform to learn*.
:) Good idea, keep it up!
That’s a good idea; it’s the practical problems that help improve learning!
What good advice; I think it’s extremely helpful for beginners
I’m very grateful for everyone’s support and encouragement! ! I’m a newcomer, so I don’t have many questions. I think there’s a question on the forum that could serve as our first lesson. Here is the link to the question: http://bbs.hcbbs.com/thread-352330-1-2.html The question is as follows: In the example related to the deethanizer, the feed conditions are as follows: Pressure – 18 bar; Vapor fraction – 0; Composition on a molar basis: HYDROGEN – 0.00014, METHANE – 0.00162, ETHANE – 0.24003, ETHYLENE – 0.75746, PROPYLENE – 0.00075; Total molar flow rate – 100 lbmol/hr. The operating conditions are: Reflux ratio – 3.1. Light key: Ethylene recovery rate – 0.95; Heavy key: Ethane recovery rate – 0.03. Condenser pressure – 17.8 bar; Reboiler pressure – 18.2 bar. Using a simplified method, it is possible to determine the number of tray levels, the feed position, and the distillation rate. Then, a more rigorous method can be used to determine the composition of the overhead distillate; by adjusting the molar reflux ratio R, the desired conditions can be achieved. My question is ① whether it is possible to specify two targets simultaneously in Blocks-B1-DesignSpecs-Object Manger, such as the yield and purity of the distillate components at the top and bottom of the tower ； ②Is it possible to define two variables under Blocks-B1-Vary-Object Manager at the same time, such as the mole reflux ratio and the distillation rate, in order to adjust them so that condition ① is met? If anyone is interested in doing it, feel free to join. There’s a group where you can communicate. In my signature. 75766926. (Haha, moderator, please don’t do this again!) ) Let’s set a time so that everyone has enough time to consider this issue thoroughly and take action. This Saturday? Let’s set a time to talk to each other. There is a group; this post was last edited by muzili2008 on 2008-12-22 at 12:05.]
This is a good suggestion; I agree to implement it and will keep doing so.
Agreed; as a newcomer, I will study hard*.
