This design is used sulfuric acid as raw material to product sulfur，thus it products sulfur without purification，the process is greatly simplified to save investment costs and gain high product quality. It is an annual output of 200,000 tons of sulfuric acid production plant process design， introduces the main methods of sulfuric acid production and mature process. The main contents include the raw material sulfur melting section，and burning sulfur conversion section，drying and absorption section and the major equipments selection，environmental protection measures. It completes various links of the chemical engineering design，and achieves the design objectives. Through the analysis of the design，design technology is reliable，and the design is economical and reasonable. In the design process，it is also focusing on wastewater treatment.
