ANNEXURE:2 A
MANUFACTURING PROCESS IN BRIEF
1. CHLORINATED PARRAFIN WAX:
Heavy normal paraffin wax or paraffin wax as the case may heated/melted in
heating tank. About 80-85oC, the mass is charged in a lead lined chlorinator.
Chlorine from toner is passed in chlorinator till required % of concentration is
achieved. This is checked by specific gravity of the materials. After completion of
chlorination, the mass is discharged in another lead lined vessel, where air is passed
to get rid of traces of HCl & Cl2. This is an aeration process.
While the chlorination is in process, HCl gas & traces of unreacted chlorine is
librated, which is scrubbed in water to get HCl as 27- 30% & excess HCl & Cl2 gas
further scrubbed in alkali scrubber.
After aeration is over, the chlorinated paraffin wax is transferred to storage tank as
final product.
2. SULPHA CHLORINATED PARAFIN WAX:
Heavy normal paraffin wax or paraffin wax as the case may heated/melted in
heating tank. About 80-85 0C, the mass is charged in a lead lined chlorinator.
Chlorine & sulphur dioxide gas from toner/cylinder is passed in chlorinator till
required % of concentration is achieved. This is checked by specific gravity of the
materials. After completion of chlorination, the mass is discharged in another lead
lined vessel, where air is passed to get rid of traces of HCl & Cl2. This is an
aeration process.
While the chlorination is in process, HCl gas & traces of unreacted chlorine is
librated, which is scrubbed in water to get HCl as 27- 30% & excess HCl & Cl2 gas
further scrubbed in alkali scrubber.
After aeration is over, the sulpha chlorinated paraffin wax is transferred to storage
tank as final product.
