Carbon dioxide desulfurization and dehydrogenation
Thread Content
The last edit to this post was made by snowdfr on 2010-10-21 at 08:51. I would like to know which design firms and research institutes are capable of designing carbon dioxide desulfurization and dehydrogenation units, as well as what their performance is like. Those who have this information could please share their contact details; thank you. Additionally, I’m interested in knowing which manufacturers produce desulfurization and dehydrogenation catalysts that have a long service life; please provide the contact details of manufacturers with good performance
There’s another question: how much does an investment typically require for a 0.9 m3 dehydrogenation catalyst?
Huasi No. 4 Institute is capable of designing carbon dioxide desulfurization and dehydrogenation units, and it has a substantial track record in this area. Our dehydrogenation has been canceled ； The desulfurization catalyst from Changge, Henan, works well.
Well-developed dehydrogenation catalysts are available from: Hubei Institute of Chemical Research, Northwest Branch, and Lanzhou Institute of Physical Chemistry
Removing H2S in Changge, Henan is feasible, but the level of COS has not yet been measured. It’s unclear what the effect will be if the COS concentration is 7 ppm
OP, what are your gas temperature and pressure respectively? At present, domestic companies are doing well in low-temperature desulfurization, but to be precise, there are no domestic manufacturers capable of ensuring effective desulfurization at medium temperatures; if sulfur removal is not effective, hydrogenation will naturally also be affected. Due to the differences in the purification processes of previous sections, most systems currently use a low-temperature methanol + liquid nitrogen washing process. The design institutes have chosen zinc oxide as the catalyst for the urea desulfurization step in order to remove inorganic sulfur, as organic sulfur can be disregarded. Currently, manufacturers of zinc oxide can only produce low-temperature zinc oxide. The above are the specific details of the manufacturers as I understand them.
