The comprehensive utilization project for desulfurization waste liquid at Shandong Jinneng was successfully commissioned in one go!

The comprehensive utilization of desulfurization waste liquid is a production process system that uses the sulfur foam liquid generated by the HPF method for desulfurization and decyanidation in coking as raw material to produce sulfuric acid; the sulfuric acid produced is supplied to the sulfuric acid ammonium sulfate production section as a raw material for the SA product. It is a \"clean production\" process device that generates no waste liquid, completely solves the pollution problem caused by coking desulfurization waste liquids, and meets environmental protection requirements. This process unit consists of a pretreatment section and an acid production section.

What is the manufacturing process, and what is the final product?

One cannot generalize based on a partial view; there is a large amount of desulfurization waste liquid, but very little of it can be utilized. Everyone defends themselves

The comprehensive utilization of desulfurization waste liquid is a production process system that uses the sulfur foam liquid generated by the HPF method for desulfurization and decyanidation in coking as raw material to produce sulfuric acid; the sulfuric acid produced is supplied to the sulfuric acid ammonium sulfate production section as a raw material for the SA product. This process consists of two parts: pretreatment and acid production. The pretreatment stage includes the centrifugal separation of sulfur foam, the concentration of the filtrate, as well as the preparation and transportation of sulfur slurry ； The acid production section comprises five processes: the combustion process (incineration of sulfur-containing waste liquids, preheating of combustion air, and waste heat recovery systems), the purification process (humidification, cooling, and demisting of high-temperature flue gases), the conversion process (conversion of sulfur dioxide and heat exchange), the dry absorption process (drying of SO2 gas and absorption of sulfur trioxide), and the final absorption process (removal of residual SO2, escaped NH3, and H2SO4 mist).

It’s similar to the pyrolysis regeneration of spent sulfuric acid, where organic substances are broken down during the pyrolysis process.

:handshake:victory: The anti-corrosion coating for the linings and the floor surfaces in the dry suction section are both products and construction services provided by our company.

Hello, please send me the process package to the email address 531841479@qq.com. I have a project that requires it, and we already have the construction drawings. Thank you.
