Sulfuric Acid Concentration System

We choose different evaporation modes are applied according to different material concentration and its impurities. The regular evaporation modes are classified into single-effect evaporation and multiple-effect evaporation, while the multiple-effect evaporation further more divided into cocurrent flow and counter flow. They’re classified into falling film evaporation, rising film evaporator or forced circulation evaporation by category, equipped with blow-off processing further more to improve the sulfuric acid concentration or remove the fluorine and chlorine from the sulfuric acid.

The diluted sulfuric acid concentration could reach 60%-96% through graphite evaporation system, which can be further more improved by tantalum evaporator.The forced circulation is suitable for evaporation and concentration of the mediums which are easy in fouling and crystallizing, with high concentration, high viscosity and mediums containing granules. The medium flowing speed is accelerated under forced circulation to avoid fouling on the internal wall leading to a bad heat transfer effect.

We choose block hole type graphite evaporator or tubular graphite evaporator could be selected according to the mediums characteristics. In addition, we choose graphite axial waterjet pump or PTFE waterjet pump could be applied according to the mediums characteristics of the forced circulation pump.
