Product Description

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:

  • Minimum maintenance needed
  • Long life
  • Flawless operation
  • Corrosion resistance

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:

  • Sulphuric acid  finds its use in textile industries
  • It is used in making detergents
  • It is used in synthesis of chemicals
  • It is used in making ferric alums, non ferric alums
  • Zinc sulphate which is used as fertilizer is manufactured by using sulphuric acid as raw material
  • Battery grade sulphuric acid is widely used in batteries
  • It is very important chemical in the laboratories
  • It is used as a dehydrant in industry

Properties of Sulphuric Acid :

  • Purity                        98.5+_ 0.3
  • SP gravity                  1.85
  • Iron contents             not more than 0.05%
  • Color                         Colorless to brown
  • Boiling point               340c (decomposes)
  • Melting point              10.5Oc

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

Sulphur is available as mined sulphur. But for Commercial purpose the Sulphur separated from Petroleum refining is used as raw material.
Sulphur is available in all the OPEC countries like, Iran , Iraq, S. Arabia, Qatar, UAE . Poland , USSR , Israel.
The approximate cost of sulphur in the international market is about US$ 58.00 Per MT

Manufacturing Process:

There are two technologies available for manufacturing of  S.A. other than the lead chamber process which is obsolete & not viable.
  • Conventional contact process
  • Double contact double absorption process
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.
