Which technology should be used for UGI desulfurization?
Thread Content
In coal-to-methanol production, where atmospheric pressure fixed-bed indirect gasification is used, what is the best approach for desulfurization? Could you all offer some advice? Let’s learn together. It would be great if the selected options could be explained. Thank you
Check the coal type. Under normal circumstances, wet desulfurization is carried out first, followed by dry desulfurization. For wet desulfurization, common agents include tannin and DDS; for dry desulfurization, agents such as iron oxide, zinc oxide, and catalysts supported on activated carbon are used. If you are interested in dry desulfurization, please call for inquiries! My email is tianyu365@yahoo.com.cn
Constant-pressure fixed-bed batch gasification is used. I think lump coal should be chosen; that’s my opinion, but I’m not sure if it’s appropriate. Please give me your advice
Currently, the PDS desulfurization technology is quite mature, easy to use, and has reasonable operating costs; if the gas flow rate is not very high, it should be an excellent choice!
