Commercial sulfuric acid is a cheap commodity and in its dilute and impure form does not have good market potential.Disposal by neutralization with lime is associated with, problems of solid (calcium sulfate) handling and also adds to the cost. To overcome these problems ASAEW offers know-how, design engineering services of sulfuric acid concentration system in which the dilute sulfuric acid generated is re concentrated to desired level for reuse. That is to say a twofold benefit of eliminating the disposal problem and minimizing fresh commercial acid requirement.
