Experimental Study of Heat Transfer Using Water - Cooled Condensers to Increase Oil Production from Plastic Waste

Abstract

This study aims to determine the performance of the heat exchanger in Low Density Polyethylene non-organic waste refining tools into fuel oil. This research is an experimental study that uses plastic waste obtained from scavengers and then cleaned, dried and chopped with a small size and then inserted into a three condenser level during a certain time. After the combustion temperature rises, water as a cooling medium is flowed in the pipe so that condensation occurs in the oil pipe. The results of the test carried out in the process of cracking plastic waste into fuel oil are affected by time, volume, temperature and heat transfer rate. Testing time for 30 minutes on the condenser obtained the heat transfer rate in the pipe 558.4 W, at 60 minutes the value of heat transfer was 732.2 W, while at 90 minutes the average heat transfer value was 1039.7 W. There was an increase in the heat transfer value as it increased Combustion time and oil produced by the reactor averaged 812 ml.
