Wet process phosphoric acid extraction and purification equipment

The phosphoric acid produced by decomposing phosphate rock with sulfuric acid, nitric acid, or hydrochloric acid is collectively referred to as wet process phosphoric acid, and the method of decomposing phosphate rock with sulfuric acid to produce phosphoric acid is the most basic method in the production of wet process phosphoric acid.

The reaction formula for rock decomposition is represented as follows:
Ca5F(PO4)3+10HNO3 == 3H3PO4 + 5Ca(NO3)2 + HF （1-1）
Ca5F (PO4)3 + 10HCl == 3H3PO4 + 5CaCl2 + HF （1-2）
Ca5F(PO4)3+5H2SO4+ nH2O == 3H3PO4 + 5Ca SO4·nH2O +HF （1-3）
When the reaction stop, how to separate the calcium salt ? this is the key point to produce the phosphoric acid economically.

The CWL-M series centrifugal extractor produced by Tiei is developed according to the drawback of conventional extractor. It is our new product which has our own patent. The patent No. is ZL2014205865573. The power consumption is only 10%-30% of traditional annular centrifugal extractor based on same condition. Meanwhile, it has advantages of short retention time, high extraction efficiency, fast to equilibrium, investment cost saving, solvent saving.

Solution 2：Multistage Liquid–Liquid Countercurrent Continuous Extraction

Multistage Liquid–Liquid Process Description:
1. The Multistage Liquid–Liquid Extraction process is not limited to four-stage pickling, alkali washing and water washing, and the number of countercurrent washing stages can be increased according to the actual situation;
2. The Multistage Liquid–Liquid Extraction process is suitable for separating organic mixtures immiscible with water such as acetochlor, alachlor, etc.;
3. The Multistage Liquid–Liquid Extraction process relies on centrifugal separation (hundreds to thousands of times the gravity under the same conditions), and the separation efficiency is high;
4. The Multistage Liquid–Liquid Extraction process equipment occupies a small area, low power consumption, and less residual liquid, which can realize the continuous production of the acetochlor washing process section;
