Regarding the H2S and COS ratio in dry powder gasification simulation
Thread Content
The H2S to COS ratio (mol/mol) that I simulate is generally close to 10:1, whereas in the design by SHELL this value is only 5-7. I would appreciate it if experts could help me analyze where the problem lies. Bro BONE, please give me some advice; it seems like you have this problem as well. Your simulated data last time was: CO 0.5371, CO2 0.0587, H2 0.2558, CH4 5e-05, N2 0.0426, AR 6e-04, H2S 0.0017, COS 0.0002, NH3 2e-04, H2O 0.1029
Bro Ren, you’re too kind. I am based on Shell’s model, and it seems that there might still be a difference in the equilibrium temperature range for the carbonyl sulfide formation reaction. Brother Ren, if you adjust this parameter appropriately, it should work fine. But it seems that Shell also relies on experience in this matter, and the results of simulations may not necessarily correspond closely to reality. Generally, when there is more CO in the syngas, COS levels should be slightly higher, while when there is more H2, COS levels are slightly lower.
I have a question: what software did the two people upstairs use to generate those results?
All of these values are calculated using chemical process simulation software such as Aspen Plus.
Some experts say PRO II can be used, but I don’t know how to use PRO II.
I’m a bit ashamed to admit it, but I’ve never used PRO II either; I’m not sure if it’s possible to enter coal-related properties in that software, but I think it should be possible. However, it seems that most people use Aspen+ for simulating gasification; perhaps this software is better at handling such tasks.
PRO/II can also be used for gasification, requiring the use of custom components. I’m not sure what value to use for the equilibrium temperature difference between COS and H2S
