The acid production process from coking desulfurization waste liquid has significant application value in the coking industry, and its advantages and disadvantages can be summarized as follows:

      Advantages

      1. Resource utilization:

      This process can convert the desulfurization waste liquid generated in the coking process into sulfuric acid products, realizing the resource utilization of waste liquid, which is in line with the concept of circular economy and sustainable development.

      2. Significant environmental benefits:

      Through the acid production process, harmful substances in desulfurization waste liquid are converted into harmless or low harm sulfuric acid products, greatly reducing the pollution and discharge of waste liquid to the environment, which meets the requirements of national environmental protection policies.

      3. Good economic benefits:

      The sulfuric acid products produced have high market value and can bring certain economic benefits to enterprises. At the same time, this process may also reduce the environmental treatment costs of enterprises, as it reduces the cost of waste liquid treatment.

      4. Mature and reliable technology:

      After years of research and practical application, the acid production process from coking desulfurization waste liquid has become relatively mature, reliable, easy to operate, maintain and manage.

      5. Solve the problem of secondary salt:

      The technical route of "wet pretreatment+dry acid production" can effectively solve the problems of sulfur paste recovery and subsequent treatment of salt containing desulfurization solution generated by wet oxidation desulfurization, while reducing the impact of secondary salts on desulfurization efficiency.

      6. Efficient and energy-saving:

      Some advanced acid production processes, such as using high-efficiency filtration equipment, triple effect evaporators, etc., can improve processing efficiency, reduce energy consumption, and achieve energy conservation and emission reduction.

      7. Small footprint and low investment:

      Compared with traditional waste liquid treatment processes, the coking desulfurization waste liquid acid production process has the characteristics of small footprint and low investment, which helps enterprises reduce production costs and save land resources.
