| dc.description.abstract | The pyrolysis method is a technology in energy conversion that can be applied in processing plastic waste into alternative
fuels in liquid form. The pyrolysis method begins with heating the plastic waste in the reactor at a temperature of more than
400°C so that the thermal degradation process of the material occurs without oxygen content, causing a phase change to
the vapor phase. The vapor phase is cooled into the condenser to convert it into a liquid phase to obtain liquid fuel from
plastic waste. In this study, the pyrolysis condenser design in changing the vapor phase from the reactor to the liquid phase
was designed using water as a coolant on the annular side with a coolant inlet temperature of 25 ° C and a coolant outlet
temperature of 35°C. The results showed that an annular side dimension with a diameter of 250 mm and a height of 250 mm
was needed to reduce the temperature of the inlet condenser fuel vapor from 60°C to 30°C. Furthermore, the inner pipe of
the condenser is made of copper material, which is formed by a spiral with a spiral diameter of 250 mm, an inner diameter
of 25 mm, and a tubing length of 4,870 mm. | id_ID |
