Hydrochloric Acid manufacturing

Hydrochloric Acid :






Introduction :

           Hydrochloric Acid was know as early as 800 A.D. Glauber prepared by heating a mixture of common salt and concentrated sulphuric acid in 1648. Presently called it marine acid while lavoisier named it as muriatic acid. It was davy who showed that it was a compound of Hydrogen and chlorine & renamed it HCL.


Manufacturing Process :

 Hydrochloric Acid is obtained by the action of hot concentrated sulphuric acid on common salt. Calculated quantities of common salt and concentrated sulphuric acid are reacted in the pan of salt cake furnace.

                          NaCL+ H2SO4  -   Na HSO4 + HCL

           Hydrochloric Acid gas produced as a result of the above reaction passes out through the exit of the top. Sodium bisulphate ( called salt cake) obtained in the reaction is removed from the pan mixed with common salt and heated strongly in the muffle.

                           NaCI + H2SO4, -   Na2  SO4 + HCL

           Hydrochloric Acid gas obtained from above two step is passed into the tower in which cold water is sprayed and diluted acid is collected at the bottom.

Market Position :
   
          The index of industries development of any country is measured by the consumption of acids. There is a great demand of   Hydrochloric Acid due to its diversified uses. The following data will indicate its gap, between the demand and supply. This product is always in short supply.So to set up the Industry for the production of  Hydrochloric Acid is always beneficial.

Require Machinery :

          1. Furnace with complete Accessories. 
          2. Cyclone separator.
          3. Colour Absorber.
          4. Absorption Tower.
          5. Storage.
          6. Exhaust fan.
          7. Accessories and laboratory equipment.
