The Production And Management Of The By-product Salt In Desulfurization Liquid

Many of China’s coal chemical industry, whether it is water, gas or coke ovengas are the main chemical raw materials. While the water-gas and coke oven gasprocessing, production of ammonia, urea, methanol, ammonium sulfate, tar, crudebenzene, naphthalene and other important industrial chemical products, must be gasdesulfurization. The desulfurization process, due to the occurrence of sidereactions desulfurization Vice salt solution will be generated, Vice salt has a greatinfluence on the viscosity, activity and desulfurization desulfurization solution,when accumulated to a certain extent, vice salt, it will greatly reduce thedesulfurization, and therefore part of the production process must be excludeddesulfurization solution, then add water softener or liquid supplement freshlyprepared desulfurization, desulfurization solution discharged through theextraction of salt and then vice reuse, due to previous environmental requirementsare not strict, most companies do not mention salt device, not to mention salttechnology is mature, not ideal.This paper mainly introduced the method of wet oxidation desulfurization method,desulfurization waste and bring in wet desulfurization of how to deal with,desulfurization waste byproduct salt to produce, I want through research, experimentand calculation, find out which factors influence the speed of by-product salt, whatare the factors that affect the by-product salt content on the system. The extractionmethod of by-product salt is also introduced, emphasis on the extraction processof sub salt. Taking Shanxi coking salt device as an example, analyzes the problemsexisting in production, from design to operation and production and the measurestaken in the future to elaborate, rich salt technology, improvement of productiontechnology, can provide technical reference value.
