Phosphoric Acid Production Process Through Defoamer

Explain How to Process Phosphoric Acid Production Through Defoamer

Aqueous solutions or adhesives are prone to the formation of foam, as it affects the appearance when the product is dried, the coating weight, performance, and flow speed of liquid. Defoamers are designed to mitigate the problems caused by foam. The foam generated through boilers, cooling towers, and effluent treatment plants arises on the surface in the form of stabilized bubbles. Defoamer’s functionality is to displace these surface-active chemicals that lead to the break of bubbles and reduce the foam. Defoamers have chemical additives that prove efficient in reducing or eliminating forms in industrial process liquids.

How to Process Phosphoric Acid through Defoamer?

Usually, there are two main commercial processes: dry and wet. The acid produced with the dry process is pure, and usually, the cost is higher than that of the wet process.

Phosphoric acid is economically produced through the reaction of rock phosphate with sulfuric acid. Defoamer for phosphoric acid

production is a common way to produce phosphoric acid through a wet process. In the wet-process phosphoric acid process, the content of carbonate and organic matter is usually high, and a large amount of Co2 is generated through a chemical reaction with acid, which hinders the plant’s production efficiency.

Carbon Dioxide is a major ingredient that contributes to the production of foam and gas generation in reactors. Significant foam on the surface can promote fugitive emissions, which could overflow during startup and lead to upset conditions and exhaust gas scrubbing systems. The bubble formation or the entrained gasses reduces the pumping efficiency and takes up valuable head space in reactors, which reduces production capacity.

Numerous impurities are ingrained in phosphate rock which acts as a surface-active agent that stabilizes gasses released in reaction making it more stable and difficult to control and diminishing the ability of gasses to disengage from reactor slurry. Usually, the phosphoric acid producers often encounter the issues of removing gasses while achieving desired plant production rates and efficiencies. Mechanical equipment such as defoamers is considered the best alternative for evacuating unwanted gasses and improving plant performance. Along with it, Defoamers for phosphoric acid help facilitate higher capacity utilization and improved output of finalized products.

with

multiple

functionalities: Defoamers are functional within phosphoric acid for prolonged periods without breaking down. This offers a reduced performance of trapped gasses that continues into multiple cycles of reaction, filtration, and recycled acid flow.

It can quickly dissolve in phosphoric acid and reactors and provide immediate results of breaking surface foam. These solutions are considered cost-effective if the foam is floating on the surface only.

It does not attack the rubber lining.
