Manufacturer of potassium nitrate by double decomposition of the production process Appropriate chemical industry
is an important inorganic nitrate, potassium nitrate acted an important role in the industrial production of the above, at present, our country's manufacturer mainly potassium nitrate by double decomposition method to produce potassium nitrate.
potassium nitrate manufacturers in China, there are two kinds of double decomposition method, a kind of based on production technology of sodium nitrate and potassium chloride as raw materials, its important stage is the crystallization of sodium chloride and potassium nitrate, solid phase is continuous analysis, start time is part of potassium chloride and potassium nitrate crystallization, and then is the crystallization of potassium nitrate. In order to get more pure potassium nitrate, potassium nitrate manufacturers need to carry on the recrystallization process.
another production technology is potassium nitrate in ammonium nitrate and potassium chloride as raw materials, the crystallization of potassium nitrate and ammonium chloride is more complex, because the radius of the potassium and ammonium ions is very close to, so in the process of crystallization, not only has a single crystallization of potassium nitrate and ammonium chloride, and part of the double salt and solid solution generation. Manufacturers in the crystallization of potassium nitrate potassium nitrate, ammonium ion and chloride ion impurities, is the crystallization of ammonium chloride, potassium ion and nitrate ions are impurities.
the process of production, the product particle size composition and purity is not only the result of the crystallization process, also can by it to estimate the kinetics of crystallization, the crystallization of potassium nitrate manufacturers to adopt suitable solution concentration or saturation solution, control the temperature and the stirring intensity and so on, makes the solid solution and double salt to generate less as far as possible.
manufacturer the double decomposition of potassium nitrate generation technology has yet to be further perfect, makes the quality after the crystallization of potassium nitrate is better.
