Sodium nitrate manufacturers - the chloride process Appropriate chemical industry

sodium nitrate is important nitrate varieties, has a very important role in industrial production, sodium nitrate products containing chlorine, affects the use of sodium nitrate and sodium nitrate manufacturers therefore need the chloride on product operation.

manufacturer of sodium nitrate from the sodium chloride and sodium nitrate solubility data to analyze, sodium nitrate solubility with temperature change obviously and sodium chloride solubility with temperature change is not obvious, the feeling can be controlled by temperature solubility making both separation, but in fact are not. Sodium nitrate evaporated into two downstream process, in the second evaporator, temperature of 70, there will be a lot of crystallization precipitation, when the temperature dropped to 50, crystal more precipitation, the lower the temperature, both common saturation curve point will move up, so the demand at the start of crystallization, cannot have the crystallization of sodium chloride precipitation. This process also is no practical significance.

in the late production, the existing production technology is unlikely to get pure sodium nitrate and sodium chloride products, in order to meet the requirements of the quality of sodium nitrate, must change the existing operation and production process. Sodium nitrate manufacturer puts forward a kind of concentrated crystallization method, the separated products 10% sodium chloride, sodium nitrate. This way need periodic operation, but I don't need to invest a new device, have solved the problem of sustainable production, as a temporary measure is feasible.

sodium nitrate manufacturers and a method of electrolytic salt water to remove chlorine. As is known to all, industry, electrolytic salt water, is the production of caustic soda and chlorine process, but when there are a lot of nitrate in the solution, the chloride ion and nitrate ion who first be electrolytic depends on the balance of potential and the potential relative size.
