Supporting coking industry

Could you provide a detailed introduction to the process flow?

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 sulfur ammonium production unit as a raw material for sulfuric acid-based AN products. 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 two parts: pretreatment and acid production.

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 sulfur ammonium production unit as a raw material for sulfuric acid-based AN products. 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 hot 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 tail gas absorption process (removal of residual SO2, escaped NH3, and H2SO4 mist).

It seems really awesome. Let’s talk about it in more detail
