1.5 A stream of 320kg/hr wax paper containing paraffin wax is to be processed to extract paraffin wax using kerosene solvent. 200kg/hr of paraffin wax is to be leached and washed at 45°C in a two stage, counter current system with 480kg/hr of kerosene. The leaching stage consists of an agitated vessel that discharges slurry into a thickener. The washing stage consists of a second thickener. Experiments show that the sludge underflow from each thickener will contain 3.2kg of overflow per kg of insoluble wax paper. List all your assumption and assuming ideal stages: Calculate the % recovery of paraffin wax in the final extract. (30)
