Distillation of Pyrolysis Results from Mixed Used Plastic and Palm Oil in The Fractionation Column to Produce the Gasoline Fraction, with RON Analysis: Experiments and Modeling
Abstract
Reprocessing plastic waste to become fuel oil is a good process. Plastics were originally obtained from the polymerization of petroleum products. According to SIPSN data from the Ministry of Environment in 2020, plastic waste in Indonesia has reached 17.314 million tons/year. In addition to using recycling, reduction can be made using hydrothermal pyrolysis cracking to convert solid plastic waste into liquid gasoline fractions with the help of co-reactants. However, with the pyrolysis process, the final result of the process allows the presence of impurities that are still contained in it. In this research, the distillation of the pyrolysis results for gasoline fraction plastic waste was carried out using a fractionated distillation column. The distillation process enhances the performance of petroleum oil with an average of RON 98 and a caloric value of 10,609,7 cal/gr. Modeling and simulation using excel of the distillation results of pyrolysis were carried out, it was found that the increase in the reflux ratio led to an increase in the purity of the distillation product and the effect of residence time caused the longer the process to run, the lower the distillation product. Therefore, the separation should not be done too long, which can cause the purity to decrease every time. The higher the reflux ratio, the smaller the kinematic viscosities get proven by experimental and modeling, but the value is a striking difference due to deviation from the model.
Keywords: distillation, RON, modeling, pyrolysis.
