Overview of new enterprises entering the domestic liquid sulfur dioxide product market
Thread Content
In recent years, there have been a considerable number of new enterprises in China producing liquid sulfur dioxide. Those who are aware of such new companies please share information – such as the manufacturing processes used, energy consumption, and measures taken for waste gas treatment. In many places, there is a lot of redundant construction and expansion, and the utilization rate is generally low. Users who use larger quantities generally equip themselves with corresponding devices. Which manufacturing process has an advantage in terms of competitiveness? I’d like to hear opinions from those with more experience
Zhejiang’s pressure swing adsorption oxygen production with sulfur combustion process, Hebei’s sulfur trioxide-based process, Hubei’s sulfur trioxide-based process for removing sublimed sulfur, Shandong’s new type of liquid sulfur catcher, Zhejiang’s homogenization washing and distillation purification method, and the oxygen-based sulfur combustion process – all of these have the great advantage of not relying on sulfuric acid production facilities. The sodium citrate absorption method, the amino acid method, and the partial condensation method yield high-quality products, but they rely on sulfuric acid facilities. Equipment: Compressor selection, spontaneous combustion in sulfur melting tanks, energy-saving technologies for refrigeration, water spray cooling towers, selection of low-temperature pumps, selection of automatic filling control systems, price trends for small-packaged sulfur dioxide, applications of vertical fire-tube boilers, applications of recycled sulfur, treatment of waste gases, wastewater, and solid waste
The 15,000-ton liquid sulfur dioxide project in Leping, Jiangxi was successfully commissioned recently, utilizing a pure oxygen sulfur combustion process as well as processes such as compression and condensation
What is the demand for liquid sulfur dioxide, what is the current production capacity, and what is the profit margin?
Liquefied sulfur dioxide is a resource-based product that is primarily used in the production of thionyl chloride, sulfuryl fluoride, nitrososulfur, saccharin, in the processing of float glass, in the food industry, in metal smelting, and also in the manufacture of sulfur dyes. Most users who consume more than 5,000 tons of this product per year already have the necessary equipment for its use; as a result, many companies use it primarily for their own needs, with sales profits ranging from 300 to 1,000 yuan per ton. The priority is to ensure that the product quality meets the requirements of users. Although the product quality exceeds the standards for top-grade items, since each user has different methods of use and different characteristics in their equipment, issues such as pipeline blockages and slow discharge from gas cylinders can still occur during use. The production capacity is generally 30 to 50 million tons per year. In China, the main processes include sodium citrate absorption method, pure oxygen method, sulfur trioxide method, partial condensation method, and amino acid method.
Hello, which domestic company uses the condensation method?
