The new technology of sodium nitrate manufacturers improve - Appropriate chemical industry

sodium nitrate is colorless transparent crystal or yellow, powder is easy to agglomerate, about sodium nitrate manufacturers produced sodium nitrate process how much you know? Today we'll learn about new technology.

current sodium nitrate factory in the production of sodium nitrate method can be summarized as two kinds: borax and soda ash. Borax method is to use so-called borax reaction between boric acid and sodium nitrate and nitric acid, then the product separation; Soda ash method is to use the same form sodium nitrate for reaction, water and carbon dioxide. Soda ash method operation is simple, but the production cost is higher, rarely used in the industry, borax method of producing sodium nitrate process requirements for equipment is low, the cost is low, is at present relatively ideal method of sodium nitrate production.

some sodium nitrate manufacturer for sodium nitrate production process, to improve, tried to get a new process for producing sodium nitrate.

sodium nitrate manufacturers using calcium nitrate and sodium sulfate to form sodium and calcium sulfate reaction, aiming at excess calcium, and add soda ash form sodium and calcium carbonate precipitation, in order to reach the goal of eliminating excess sodium carbonate, add in nitric acid, finally returned to the existing method of soda ash. The whole process carried out in accordance with the proportion, although a slight increase production cost, but it could produce high quality and not easily deliquescence sodium nitrate. Sodium nitrate factory to modify the original equipment, can realize industrialized production.

looking forward to the birth of more sodium nitrate production process, if you have any good Suggestions or the need for sodium nitrate are appropriate consulting Shanghai xin chemical wholesale!
