Comparison of sulfur recovery processes and their prospects
Thread Content
The main process I am currently familiar with is wet flue gas desulfurization, and the product produced is sulfuric acid. With dry desulfurization, sulfur is produced – what kind of processes are people using? Let’s talk about and compare them, looking at the advantages and disadvantages of various processes, as well as possible ways to improve them.
What do you mean by dry and wet desulfurization?
There’s a lot of comparative information on this topic in the forum; you should search for it first.
It seems that dry and wet desulfurization methods aren’t related to sulfur products, but I’m not entirely sure; I’ll check the answers from other experts
What type is the ultra-high-efficiency Claus desulfurization used in urea production? ? ? ?
The product of wet desulfurization should be sulfur foam; after this sulfur foam is melted in a sulfur melting furnace, sulfur is produced. http://wenku.baidu.com/view/a848ccf9f705cc175527099a.html
In my opinion, dry desulfurization refers to the use of zinc oxide or iron oxide for desulfurization, while wet desulfurization involves the use of EDTA or other solutions for this purpose. It’s not that the product produced is sulfur or sulfuric acid.
There is actually no strict boundary between these two methods; it mainly depends on the manufacturer’s requirements for the product and market assessments； The wet process does not necessarily always produce sulfuric acid, and the dry process is not incapable of producing it either ； Currently, there are probably more places that produce sulfur, after all, the costs associated with transporting and storing sulfur are lower.
After dry desulfurization, the Claus process is generally used to produce sulfur, while in the wet method salts are obtained; however, some of these salts are difficult to extract
Dry and wet methods are referred to in relation to hydrogen sulfide; sulfur recovery processes include the Claus process and the Loquette process
