Sulphuric Acid Plant
We are offering quality engineered Sulphuric Acid Plant, which is used in the chemical industry for producing fertilizer, inorganic, synthetic fiber, dyes, medicines and raw materials for food industry. In addition to this, our plants are used in the oil industry for refining products related to petroleum. The other application area of this is defense industry and it is used to produce of poisons and smoke. Our Sulphuric Acid Plant is also used for smelting pickling in the metallurgical industry. Dyeing and bleaching are the important work done by the plant in the textile industry. We use fine quality raw materials, cutting edge technologies and best available knowledge for making the plants efficient as well as outstanding. In addition to this, our plants are designed by team of engineers, which is experienced and know the pros and cones for designing the same.
Features:
Introduction : Sulphuric Acid is called King of Chemical. It is called so because of its multiple use in different spheres of life. Sulphuric acid was known to the ancient people who use to make alums with it.
Uses of sulphuric acid:
Properties of Sulphuric Acid :
Handling:It is handled in Mild steel vessels and tankers. MS is very safe material although SS can also be used. It can cause burn if come in contact with human skin. It starts fuming in open so that vessel has to be closed. Plastics are also good material provided they have sufficient strength.
The sulphuric acid should be handled with extreme care . The person working with it should always use rubber hand gloves, gum boots, face shield and plastic helmet. The water shower should be provided near the handling point

Manufacturing Process: There are two technologies available for manufacturing of S.A. other than the lead chamber process which is obsolete & not viable.
Both of the technologies are same fundamentally but they differ in application. Sulphur is burnt in dry air to form sulphur dioxide. The sulphur dioxide is made to react with oxygen from air to form sulphur trioxide. The sulphur trioxide is absorbed in sulphuric acid to concentrate it. Water is added continuously to maintain the desired concentration. In conventional process the above mentioned process of conversion and absorption is performed once while in DCDA it is done twice for better efficiencies. The conventional contact process is cheap in the cost of plant and machinery , inefficient in conversion and absorption efficiencies, poor in heat recovery. It does not meet the pollution specifications of many advance countries so this technology is no more allowed in India. The double contact double absorption process uses costly plant and machinery , efficient in conversion & absorption efficiencies, very efficient in heat recovery, & the pollution Control. The Selection of process is entirely depends on the customer. If the customer is interested in better heat recoveries , better conversion and absorption efficiencies, lower raw material consumption per ton, and environment friendly technology, then he has to opt for DCDA process. If he has got some source to sale /use of steam, DCDA process is far superior cost wise also as the payback period for the steam system is less.
