Design and Fabrication of system to Produce oil from waste plastics

Abstract

The study focused on the design and fabrication of a waste plastic oil converter as an effort in finding environment-friendly means of waste recycling. It is an alternative solution to increasing problem of waste disposal by converting waste plastics into a resource. Pyrolysis process was the basis in the design and fabrication of the equipment. It is a prototype/laboratory scale model that will serve as baseline in developing technology for energy. recovery from waste plastics. The main components were the reactor assembly, condensing chamber, vapor line assembly, the reactor tank is made of steel sheet with holding capacity of 200g/batch of waste plastic. The equipment was tested for five trials using 200g of Polypropylene (P.P) plastics per trial. The temperature was controlled at 400℃ and operating hour of 2 hours. Test result showed that the equipment is functional with conversion efficiency (wt %) of 61.8%, waste reduction efficiency (wt %) of 94.3% and oil recovery of 800 ml oil/kg of Polypropylene plastic.
