aspen simulates biomass gasification problems
Thread Content
Can the flow chart of biomass (such as wood chips) simulated with Aspen be made into the same flow chart as coal gasification (a RYIELD module + a RGIBBS module)? If so, does it only need to be distinguished from the percentage of each component of coal when inputting industrial and elemental analysis? Or are there any other differences that need to be paid attention to? Could you please help me to answer, I am new to Aspen software! Waiting online~~~~~Thank you!
Brother, why have you fallen into the sea of misery like me? You have to suffer aspen!
That expert can come over and give us some advice, so that we, the beginners, can* one time!
Why is no one answering? Experts come and take a look.
LZ didn’t explain what he wanted to do, and of course others don’t know what you want to do! The question is very unclear, so I can only briefly introduce it! RYIELD module: Yield reactor. The reaction is carried out according to the yield relationship between each product and the input stream. Only the total mass balance is considered, and the element balance is not considered. We only know the chemical reaction formula and the relative yields of each product, but we do not know the stoichiometric relationship. Use this module to play the "straw to gold" game. RGIBBS module: Gibbs reactor. According to the principle that the Gibbs free energy of the system tends to the minimum value, the system composition and phase distribution when chemical equilibrium and phase equilibrium are reached at the same time are calculated. Knowing the chemical reaction formula, but not knowing the reaction process and kinetic feasibility, estimate the possible chemical equilibrium and phase equilibrium results.
Thank you for the answer upstairs! What I want to ask is whether it is possible to imitate the case of coal gasification to do biomass gasification? Both can be defined as unconventional components, but the composition of the components in industrial and elemental analysis is different, and other places are roughly the same. Can it be understood in this way?
Of course, biomass gasification can be done imitating the case of coal gasification. Using the RYIELD module, you can perform C->Gold reactions. It is certainly a small case to deal with coal gasification or biomass gasification! That’s understandable!
OK. There are many ASPEN documents on biomass gasification. If you search on VIP, you will find the basic model, which is currently similar to coal gasification.
The literature is all about generalizations. It would be great if there was a ready-made case. I wonder if anyone has done it.
Biomass gasification is indeed difficult to do. Before doing it, you must be familiar with the operating mode of aspen, the characteristics of this simulation, and various necessary data! It’s so difficult, my head is too big to do!
Brother upstairs, you also do biomass vaporization. Do you want to do your graduation thesis? If yes, we can communicate together. I don’t know much about Aspen and biomass vaporization. I hope we can discuss it together! My QQ754638344
