The present status of the manufacturer of potassium nitrate production technology development in China Appropriate chemical industry

potassium nitrate in China is the main production process of ion exchange method and double decomposition method, but that there are shortcomings of each production process, seriously restricts the use area and production capacity of potassium nitrate in China, in order to develop our country's industrial potassium nitrate, a lot of potassium nitrate manufacturers began the research on the development of potassium nitrate production process.

some of potassium nitrate manufacturers of double decomposition method is adopted to produce potassium nitrate, potassium chloride and ammonium nitrate as raw materials, potassium nitrate and ammonium chloride is obtained by double decomposition reaction, after crystallization can get potassium nitrate, and add potassium chloride and then can be formed with potassium nitrate as the main content of the mixture, and thus can be recycled to the production of potassium nitrate. At the same time, the potassium nitrate manufacturers can also use a loop of double decomposition method to produce potassium nitrate, and the rest of the mother liquor can be used as potassium chloride fertilizer. This method is easy operation, less investment and quick effect, but the product in appearance and grain size on some differences, for industrial grade a of potassium nitrate, recrystallization processing is needed.

potassium nitrate factory is trying to circulate in a production process, raw material belongs to inner loop using sodium chloride and ammonium nitrate, end up with potassium nitrate, a by-product is a light calcium carbonate and ammonium chloride. The inner loop method using sodium chloride can reduce cost, and avoid the environmental pollution caused by sodium chloride wastewater, each step of reaction raw material waste not, product easy to control, is an ideal production methods.
