Water Based Defoamer Chemical Supplier
If simply bifurcated, Defoamer results in “De” and “foamer”, which implies those additives that help prevent the formation of foam or those additives that, when added to the already formed foam, pacify it, decreasing it wastage of the material. As in industrial processes, foam generation poses serious problems.
Before we delve deeper into the concept of defoamers and how it is applied to phosphoric acid production, let’s discuss a little bit about the phosphoric acid production process.
How Is Phosphoric Acid Most Commonly Produced?
Phosphoric acid is most economically produced through a now decades-old process involving reacting rock phosphate (typically coming from mines and undergoing a beneficiation process) with sulfuric acid or a mixture of sulfuric acid and varying strengths to give calcium sulfate and phosphoric acid. In this way, defoamers for phosphoric acid production are most commonly called producing phosphoric acid defoamer through the wet process.
Why Is There Foam In Phosphoric Acid Production?
There are typically many answers to this question, primarily because a lot of the foam depends on the kind of phosphate rock used in the reaction. After the phosphate rock is obtained from the mines, it often needs beneficiation to prepare the defoamer for phosphoric acid production. Several chemicals and solutions are used in the beneficiation process, and to get the optimum performance from a phosphate rock beneficiation process, NAQ Global’s mining products are excellent. A reason for foam generation is the characteristics of the flotation agents used as collectors for phosphate rock concentration. Thus, high-quality flotation agents, such as vegetable oil-based collectors made by NAQ Global, can optimize the process. Even after beneficiation, certain impurities in the phosphate rock can give several side reactions. Since phosphoric acid defoamer chemical is produced in large reactors, the problems from these side reactions are exacerbated. Foam generation is one of the biggest issues because of these side reactions, and foaming is further intensified depending on the rock and ore quality.
Why Is The Foam Troublesome, And What Are Some Ways To Solve It?
A lot of this foam amasses on the top of the reactor volume and is often difficult to be broken by mechanical means. Since this foam accrues on the top, the more the foam, the less the volume available for the reaction to occur in the reactor. Thus, foam generation drastically reduces the production capacity of the reactor and hence the production capabilities of the phosphoric acid plant. Thus, control of foam that accumulates on the top of the reactor is often a significant factor that determines the comfortability of operations of a phosphoric acid plant. Regardless of the phosphoric acid plant being DH, HDH, HH, Central Prayon Process, Di-hydrate Attack, and Hemi-Hydrate Filtration, foaming is the most common capacity limiting issue in the reactor. NAQ Global has developed a wide range of products for addressing all foaming issues in all types of phosphoric acid plants. Highly effective defoamers break the foam by acting on the surface tension to break bubbles created in the phosphoric acid reactor. Like the ones made by NAQ Global, sophisticated defoamers do not attack the rubber lining of the reactors.
NAQ GLOBAL manufactures and supplies specialty defoamer chemicals for Phosphatic fertilizer plants. Whether it is Hemihydrate, dihydrate, Hemi Di, or Di Hemi process, NAQ GLOBAL provides tailor-made defoamers – GREEN DEFOAM series for Phosphoric acid defoamer plants to give the best techno-commercial solution. We are the leading Defoamer Chemical Supplier and manufacturer. We manufacture water based defoamers chemical, oil based defoamers chemicals, and other antifoam Agents.
Defoamers for foam suppression in fertilizer plants are also manufactured and provided to fertilizer plants.
A common problem with many conventional defoamers is that they attack the rubber lining of the reaction vessels. The deterioration of the rubber lining often causes many problems in the operations of a phosphoric acid plant. Our most sophisticated water-based defoamers do not attack the rubber lining of the reactors. With these defoamers being completely water-soluble, fewer contaminants are handled in the ETP.
