Then start cooling through jacket. The total reaction time is 24 hrs. After that, keep for a layer separation. Bottom layer is taken into collection tank of ETP for treatment. Upper layer is neutralized with caustic lye. Then given wash of hot water. Further keep for a layer separation. Bottom layer mainly water is taken into collection tank of ETP for treatment. Steam is given to the upper layer for moisture removal. After removal of steam; mass is directly packed in a drum as a finished product.
