Experience and techniques regarding dual-stage desulfurization?
Thread Content
Currently, based on the characteristics of tannin-based desulfurizers and titanium-chromium-cobalt series desulfurizers, in order to avoid their respective disadvantages and make use of their advantages to achieve a complementary effect, I am wondering if any organization has experience and expertise in using both types of desulfurizers. If anyone knows anything about this, I would appreciate it if they could share their knowledge
To date, manufacturers have not conducted any statistics on desulfurization using this method; it has been in use for several years now. It isn’t just titanium cyanocobalt and tannin that are used, but also titanium cyanocobalt together with K.C.A. and MSQ. It’s just that at that time, no one called it dual-catalyst desulfurization.
Reply 1# czzjm: The gum-based desulfurization agent has a large processing capacity, strong desulfurization efficiency, and good results; however, it has its drawbacks – it can cause blockages in the tower after long-term use. The 888 desulfurization agent, on the other hand, helps to clean the tower. By combining the two, we achieve what you refer to as dual-desulfurization. Our plant has two systems that both use dual-stage desulfurization; one is working properly while the other isn’t, and I’m not aware of the specific reason for that.
