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.
Concentrated Sulfuric acid (H2O4 98%) Application Manufacture of fertilizers. As an oxidizing and dehydrating agent. Manufacture of explosives. Treatment of metals. Purification of petroleum. Manufacture of dyestuffs. pH control.
Pure sulfuric acid does not occur naturally due to its strong affinity to water vapor; it is hygroscopic and readily absorbs water vapor from the air.[6] Concentrated sulfuric acid is highly corrosive towards other materials, from rocks to metals, since it is an oxidant with powerful dehydrating properties. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is released; thus, the reverse procedure of adding water to the acid should not be performed since the heat released may boil the solution, spraying droplets of hot acid during the process. Upon contact with body tissue, sulfuric acid can cause severe acidic chemical burns and even secondary thermal burns due to dehydration.[7][8] Dilute sulfuric acid is substantially less hazardous without the oxidative and dehydrating properties; however, it should still be handled with care for its acidity.

Commodity: Dicalcium phosphate Feed Grade Use DCP is the feed preparation of raw materials, Animal right to supplement calcium needs. Coarse its products more applicable to the preparation hens, ducks feed, concentrate feed and premix. Product Nature Molecular Formula:CaHPO4·2H2O,Molecular weight:172.09,After drying with loose white powdery crystals or granules. Neutral products, the melting acid, water-soluble, hygroscopicity small, heated to 90 around gradually lose water of crystallization. Product Features The purity of the product, calcium and phosphorus ratio appropriate to ensure a higher degree of its biological effects. Phosphorus content greater than 18% of the products, due to a small amount of MCP, and its biological effects better. This unique high-tech companies use technology to make our products crystallization, high purity and its harmful impurities significantly below standards:HG26362000 Drying process advanced products, products with low free water under the premise that the product does not lose crystallization of water, avoid the product in the drying process for the loss of water caused by crystallization of biological effects of the reduction. Coarse particle DCP in the animals stay in the stomach longer and more conducive to the absorption of calcium phosphate, the product of Micro-particle DCP granulation from mechanical, without any chemical binder.
