OAN D 35 is a defoamer most effective in the manufacture of Phosphoric Acid. The reactions involved in the synthesis of Phosphoric acid evolve large volume of CO2 and some Hydrogen fluoride gas which results in substantial amount of foam. The foam thus produced hinders the reaction process by reducing the capacity of the equipment. OAN D 35 helps to eliminate the foam produce during the reaction and increase the capacity of plant. OAN D 35 is a very effective defoamer for Phosphoric acid manufacturing plants.
