The issue of precise desulfurization of blast furnace gas
Thread Content
A project to carry out advanced desulfurization of blast furnace gas was planned, but due to certain issues, only the hydrolysis conversion + wet desulfurization process could be used. This process generates sodium sulfide solutions as by-products; the main by-products are sodium sulfide and sodium sulfite solutions, with an annual output of around 1,217 tons in dry basis. ), I’m looking for a way to deal with it, or rather to create some new project that allows for recycling and reuse ； Additionally, there are the by-products of SDS+SCR, namely sodium sulfate and sodium sulfite (about 1,000 tons per year); can these also be disposed of together? Help, please!
There’s only way to deal with this; the previous process wasn’t suitable, I guess
