钢铁企业焦化脱硫废液浓缩制酸工程为环保工程,脱硫废液浓缩制酸工艺成熟可靠,技术先进,生产操作稳定,硫酸产品质量好,从根本上解决HPF脱硫工艺硫磺品质差和脱硫废液二次环境污染问题,真正实现了变废为宝,生产的硫酸直接用于煤气净化的脱氨装置制取硫铵,符合国家发展循环经济政策和环保要求。然而,脱硫废液浓缩制酸的同时亦会产生少量的废气、废水、噪声等污染物,还需采取各种有效控制治理措施,使污染物的排放达到相应标准的有关规定。
Iron and steel enterprises coking desulfurization waste acid concentration of acid projects for the environmental protection projects, desulfurization waste liquid enrichment acid plant technology is mature and reliable, advanced technology, production and operation stability, good quality sulfuric acid products, fundamentally solve the HPF desulfurization sulfur poor quality and desulfurization waste Secondary environmental pollution problems, the real turning waste into treasure, the production of sulfuric acid directly used in deamination gas purification device for the production of ammonium sulfate, in line with national development of circular economy policies and environmental requirements. However, when the desulfurization wastewater is concentrated and acidified, a small amount of pollutants such as waste gas, waste water and noise will be generated, and various effective control measures need to be taken to make the discharge of pollutants meet the relevant standards.
