Manufacturer of potassium nitrate production method Appropriate chemical industry

on the market at present, the method of production of potassium nitrate, potassium nitrate manufacturers are always research new methods of production, then we will introduce the main kinds of production methods.

a synthesis

after the manufacturer with nitric acid potassium nitrate and potassium chloride reaction potassium nitrate, the downside of this approach is reaction produces chlorine, chlorine gas generated will cause serious corrosion of equipment phenomenon, but also caused the waste of resources.

2 ammonium nitrate process

potassium nitrate manufacturers will be double decomposition reaction of ammonium nitrate and potassium chloride to the preparation of potassium nitrate, by-product generated for ammonium chloride, because of lower cost, so at present our country about 60% of potassium nitrate factory in this way.

the three absorption method is potassium nitrate with potassium hydroxide to absorb the nitric acid tail gas, but the price of potassium hydroxide is expensive, so rarely used.

four ion exchange method manufacturer or zeolite using ion exchange resin, potassium nitrate with potassium chloride and nitrate as raw material, according to the cation exchange resin of potassium ammonium ion adsorption characteristics, close to the role of using cation exchange resin, potassium chloride and ammonium nitrate solution of potassium ion exchanged, potassium nitrate solution. At present there is also a part of the potassium nitrate factory in this way. Five reforming process

potassium nitrate manufacturers use sodium nitrate and potassium chloride to get double decomposition potassium nitrate, which is reforming process. This method is simple, high product quality, in the industrial used more. This method also has its shortage of place, potassium nitrate factory in evaporation crystallization process is easy to occur explosive boiling phenomenon, does not favor the multi-effect evaporation and precipitation of kno3 crystal quality will be slightly less.

potassium nitrate manufacturers also has been studied the new production technology, can solve of the insufficiency of the traditional process, and can save cost and improve the economic benefit.
