What is Wet Process Phosphoric Acid？

Wet process phosphoric acid production is a process used to produce phosphoric acid from phosphate rock. It involves the reaction of sulfuric acid with phosphate rock, which produces phosphoric acid and calcium sulfate (gypsum). The gypsum is then separated from the phosphoric acid by filtration or centrifugation. The resulting phosphoric acid can be used in various applications, such as fertilizers, food additives, and detergents.

Harm of foam for Wet Process Phosphoric Acid

Foam can be a problem in wet process phosphoric acid production because it can interfere with the chemical reactions taking place in the process. Foam can reduce the efficiency of the reaction, resulting in lower yields and increased costs. Foam can also lead to corrosion of equipment and pipes, as well as safety hazards due to the risk of foam overflowing and spilling onto personnel or equipment.

Good advantage of defoamer for Wet Process Phosphoric Acid

1. Defoamers help reduce the amount of foam that forms on the surface of the acid, making it easier to handle and store.

2. They also help reduce the amount of time needed to clean up spills and other accidents involving phosphoric acid. 3. Defoamers can also help reduce corrosion caused by foam in tanks and other equipment used to store or process phosphoric acid.

4. Finally, defoamers can help improve the overall efficiency of the process by reducing foaming and allowing for more efficient production rates.

What defoamer is used for wet process phosphoric acid?

The most common defoamer used for Wet Process Phosphoric Acid is a polyglycol-based defoamer. This type of defoamer is designed to reduce foam and prevent foaming in the process. But it need to be good for

excellent defoaming and foam control performance, high temperature resistance andstrong acid resistance.
