Potassium nitrate manufacturers metathesis method - three-step cycle Appropriate chemical industry
at present, the factory main production of potassium nitrate potassium nitrate by double decomposition method of four-step cycle process, the production process to a certain extent, there is insufficient, so some potassium nitrate manufacturers metathesis three-step process is presented in this paper, greatly improved the production mode.potassium nitrate factory four footwork decomposition method is add potassium chloride in cycle for liquor production technology, after cooling crystallization of potassium nitrate, and then join the ammonium nitrate, after evaporating, cooling crystallization from ammonium chloride, mother liquor recycling. This method, there are two shortcomings exist, is the moisture in ammonium nitrate solution need to evaporate in the process of production, thereby increasing the energy consumption in the production process, extend the production time, it increased the cost of production for potassium nitrate manufacturers; Second, potassium chloride and ammonium nitrate is a time interval to join, to plant large-scale continuous production operation. potassium nitrate manufacturers metathesis three-step process mainly has three steps, first is the batching process, the semi-finished products of ammonium nitrate after dissolved in potassium chloride and a small amount of additives dissolved, after removing impurities with mother liquor of ammonium mother liquor tank to mix evenly. Followed by family separation process, the solution into the cooling fluid, separation of potassium nitrate crystallization. Finally, the evaporation process, the finished product will get the moisture to evaporate, potassium nitrate production. manufacturer of potassium nitrate by double decomposition of three-step method is particularly suited to production process semi-finished products production of potassium nitrate, ammonium nitrate solution greatly reduces the production cost, believe that there will be more production technology was born.
