Foreign manufacturers of potassium nitrate production process - in this review Appropriate chemical industry

potassium nitrate potassium nitrate manufacturers abroad mainly by nitric acid and potassium chloride as raw materials, the production process is different, then, we came to know about the production technology of several major foreign.

potassium nitrate manufacturers using potash technology in the United States, the so-called technology of potash is under high temperature, potassium chloride and potassium nitrate and nitrosyl chloride generated by nitric acid reaction and chlorine, and then in the acid concentration in the distillation tower in nitric acid concentration of 81%, in the bottom sediment to vacuum crystallizer, precipitate potassium nitrate, and separated by means of centrifugal, so worthy of potassium nitrate purity can reach 99%, the reaction condition is harsh, severe corrosion and has gradually lost its competitiveness in the world.

the manufacturer also using potassium chloride and potassium nitrate of Israel nitric acid reaction to preparing, manufacturer USES isoamyl alcohol to remove the reaction product hydrochloric acid, potassium nitrate precipitation in, under the condition of low temperature reaction, can effectively prevent the nitryl chloride production. This method is mature, reliable and production costs are less competitive. Most manufacturers use this method to produce potassium nitrate agricultural grade potassium nitrate.

is Chile's largest producer of natural saltpeter, saltpeter contains a large amount of sodium nitrate. Chile production of potassium nitrate mainly saltpeter as raw materials and potassium chloride to get double decomposition reaction, this method is similar to using potassium chloride and sodium nitrate as raw materials for production in China.

a foreign manufacturer of potassium nitrate production methods are diverse, but all have their own limitations, looking forward to more energy efficient, more efficient production technology was born.
