Process Description :
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 :
VSK technology is used to manufacture clinker on small scale. The plant is small and easy to operate. The Raw Materials :
|Iron contents||not more than 0.05%|
|Colour||Colourless to brown|
|Boiling Point||340c (decomposes)|
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.
|Chemical formula||S wt 32.06|
|Shape / size Colour||crystals & lumps / powder bright yellow or black|
|Moisture||not more than 1 %|
|Storage||In open bins. It does not Absorb water|
|Consumption / MT||0.332|
|Category||covered under explosive|
|Fire / Burning||gives pungent SO2 gas on burning. Water is used to extinguish fire. Fire does not spread fast.|
|Melting Point||117c ( 112.8. oc to 119.2 oc)|

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
