Abstract:
The purpose of this study was to determine the effect of the diameter of the heat exchanger on the formation of fuel oil from plastic waste. The raw material for plastic is polypropylene (PP), which is used to package mineral water. The research method used is an experiment to make plastic oil by pyrolysis. The procedure uses a kilogram of polyethylene. The raw material is cut into small pieces before being put into the pyrolysis tube. The result of this study is that the maximum temperature of the reactor (Tmax) is inversely proportional to the diameter of the heat exchanger used. The average volume of fuel oil produced in each variation of heat exchanger diameter is 0.625 L, 0.8 L, and 1 L, respectively. The average calorific value of the fuel produced in pyrolysis with a heat exchanger diameter of 1/2 inch, 3/4 inch, and 1 inch, respectively, is 10899.67 cal/gr, 10945.33 cal/gr, and 11062.33 cal/gr.
