Main production methods of potassium nitrate manufacturers abroad Appropriate chemical industry

now, in the domestic use of potassium nitrate is mainly in shanxi, salt and other manufacturers to provide potassium nitrate, potassium nitrate for its purity, could be divided into industrial grade, superior quality and high purity. Today, we know about the foreign manufacturer of potassium nitrate production methods.

a southwest of potash technology

American manufacturers using potash technology to produce potassium nitrate, potassium nitrate reaction principle is to make the potassium chloride and nitrate in 172 kpa, under the condition of 75 ℃, the reaction of potassium nitrate and nitrosyl chloride and chlorine, centrifugal separation and filtration to get high purity potassium nitrate, its purity can reach 99%, but in the United States manufacturer of potassium nitrate by using the technology of potash harsh reaction conditions, serious corrosion of equipment, investment is bigger, therefore has lost its competitiveness in the world.

two Israel low-temperature extraction technology

potassium nitrate factory by adopting the technology of extraction, extraction technology is at low temperature, the potassium chloride dissolve in nitric acid, add alcohol and other organic matter at the same time, the removal of hydrogen chloride, potassium nitrate crystallization precipitation. Manufacturer of potassium nitrate production technology mature reliable, the extraction method of large production experience, fewer investment, and has good prospects for development, but the process is more complex, separation technology did not meet the requirements of industrialization. Three ion exchange process in the United States

some U. S. manufacturers by ion exchange method to produce potassium nitrate, potassium nitrate this method less investment, material consumptions index is low, downside is that the energy consumption is higher. This for potassium nitrate manufacturers, there are still some challenges. Four Chile SQM company reforming process technology

Chile is the world's largest producer of saltpeter, therefore Chile manufacturer by reforming process to produce potassium nitrate, potassium nitrate this method is similar to potassium nitrate in China manufacturer of double decomposition method.

this is introduced in four foreign manufacturer of potassium nitrate production methods, you must have some idea of it, to learn more the knowledge of the manufacturer of potassium nitrate, showing the appropriate consulting Shanghai xin chemical industry!
