Potassium sulfate production process principle of the project, with sulfuric acid and potassium chloride as raw materials, reaction at high temperature, made a series of processing technology, production of main products of agricultural potassium sulfate and the by-products of industrial hydrochloric acid. By the technical supervision inspection, potassium sulfate reached GB20406-2006 product quality standard level, among them, the content of potassium hydroxide, chlorine ion content, moisture content and physical properties of various specifications are reaching or higher than similar foreign products. 31% byproduct hydrochloric acid can be adjusted according to the customer need the following products, various concentration of quality BG320-2006 standard requirements.
2.Main Features of Potassium Sulphate(SOP)：
• Potassium sulfate contains both crops necessary potassium ion，contain sulfur in promoting role for the growth of crops, is a kind of potassium and sulfur compound fertilizer, used for all crops, particularly applicable to avoid chlorine crops, such as tobacco, tea, sugar beet, melon, potato, peanuts, beans, vegetables and so on, can not only increase crop yield, but also can improve the quality of crop products. For example, can raise the flammability of tobacco, the sweetness of grapes and watermelon, potato starch and so on, with chlorine, phosphorus is reasonable use of 10-25% of the increase production effect can be obtained. Because of lower potassium sulfate index, use for a long time without destroying the soil structure, it will also no longer cause soil acidity and salinization.
• This project of by-product hydrochloric acid production, the quality meet or exceed the technical indicators of industrial synthesis of hydrochloric acid requirements, can be widely used in industrial boiler water electrolysis, electroplating, purification and chemical industry and so on equipment cleaning, also can be used for processing fields such as food, medicine, is one of the basic chemical raw materials, has a broad market prospect.
