[HCl] Hydrogen chloride gas to produce wet-process phosphori
Pub Time：2021-04-08Source：Views：1668
A method for producing wet-process phosphoric acid. The slurry is prepared with water, phosphate rock powder and additives, and hydrogen chloride gas is directly introduced into the decomposition reaction to obtain filtered acid. After cooling and aging precipitation, the fluoride salt and other harmful impurities are removed to obtain high-quality Phosphoric acid, calcium chloride solution. The solution is easier to be processed into pure phosphoric acid by using the existing extraction and refining technology, or the yield of feed-grade calcium hydrogen phosphate is 100% in one step, it does not pollute the environment, and various technical and economic indicators are relatively advanced.
