Importance of Defoamers for Phosphoric Acid Production

The "wet process" synthesis or the production of phosphoric acid evolve around some hydrogen fluoride gas and large amounts of carbon dioxide which results in developing extensive amounts of foam. It can hinder the process by reducing the equipment capacity used in the many process steps and can results in overflows of foam, making it dangerous for the plant because of the caustic properties of phosphoric acid.

Many defoamers are apparently effective during "wet process" manufacture of phosphoric acid. Yet it is apparent that the normal phosphate rock used in this acid industry is of a lesser quality now-a-days than used before. The poor quality causes rise in the formation of foam during the wet process manufacture of phosphoric acid. Hence the advent of an improved defoaming agent has arrived.

This new and much powerful kind of defoamers are now comprised of a mixture of defoaming effective amounts of monocarboxylic acid, a monoalkanolamide, derived from a monocarboxylic acid and a monoalkanolamine and a primary linear aliphatic alcohol.

The use of alcohol additive is an important turn for the making of these defoamers. Alcohol additives are found to have synergistic effect along with fatty acid alkanolamide and fatty acid. The addition of alcohol has increased the effectiveness of the defoaming composition of the defoaming agent. The addition of small amounts of alcohol has an important and significant effect upon the defoaming capability of the defoamer composition of the invention.

These new types of defoamers that are specially made for phosphoric acid production can improve the quality of the phosphoric acid making process by removing foam from it totally and making the process less dangerous and efficient for the plant. So, Defoamer for Phosphoric acid production is very crucial if you’re looking for safety, quality,profit of your plant in the long run.
