Abstract

Pyrolysis is a promising alternative for managing the substantial amount of low-density polyethylene (LDPE) plastic waste, particularly plastic bags. The high temperatures in the pyrolysis reactor can vaporize the plastic, necessitating a condensation process to capture this vapor as a liquid. The condenser design is crucial for maximizing this process and preventing the release of polluting oil vapor. Fized bed pyrolysis reactor with a capacity of 0.8 kg of plastic waste equipped with a water-cooled condenser made of copper pipe with a diameter of 3/8 inches and an overall length of 2000 mm. The copper pipe with a thermal conductivity of 386 W/m.K is formed in a spiral model with a coil diameter of 14 cm and a total of 10 coils. This study experimentally compared the performance of a water-cooled condenser in counter and parallel-flow configurations. The pyrolysis temperature operated at 300℃ with a constant water flow rate of 3 liters per minute. The results indicated that a counter-flow condenser produced a higher volume of condensate (765 ml) compared to a parallel-flow condenser (680 ml). The counter-flow design was more effective in reducing non-condensable gases and mitigating the risk of environmental pollution.
