PENGARUH JUMLAH LILITAN PIPA KONDENSOR TERHADAP KUANTITAS MINYAK PIROLISIS SAMPAH PLASTIK

Abstract

The large use of plastic in everyday life will certainly have an impact on the environment. One of the methods of processing this plastic waste is by pyrolysis method. In the pyrolysis process there is a condensation process. The condensation process is a process where when saturated steam comes into contact with a surface with a low temperature, there will be a process of heat release from a system that causes the vapor to turn into liquid. The component in charge of this condensation process is referred to as a condenser. The geometric shape of the condenser will affect the heat transfer process that occurs in the condenser. The purpose of this study is to determine the effect of the number of windings in the condenser pipe on the effectiveness of the condenser, distillation efficiency, technical efficiency as well as the quantity of oil produced during the pyrolysis process. This study uses an experimental method where this research will later vary the number of windings of condenser pipes with the number of windings of 5, the number of windings of 7 and the number of windings of 10 to determine the value of condenser effectiveness, distillation efficiency, technical efficiency and quantity of oil produced from each variation and which variation is more optimal The highest oil yield is found in variiation 3 with a total of 10 windings, which is 148 grams, while in variations 1 and 2, each of them only gets 75 grams and 110 grams of oil. The effectiveness of the condenser also increases along with the increase in the number of windings in the condenser pipe, namely for variation 1 by 16%, variation 2 by 62% and variation 3 by 76%. In addition, Distillation efficiency and technical efficiency also increase as the number of windings in the condenser pipe increases. The most results were obtained in variation 3 with the number of windings of 10 with a distillation efficiency of 90% and a technical efficiency of 12%.
