Can plastic be converted back to oil? How to make fuel oil from waste plastic?

Plastic is commonly found in household waste. Can plastic be recycled and converted into new energy sources? The answer is that plastics such as PP, PE, and PS can be converted back into fuel oil using pyrolysis machines, while PET and PVC cannot undergo pyrolysis.

This article introduces the process of making fuel oil from waste plastics using the DOING plastic pyrolysis machine.

The first step is feeding. The entire feeding process only requires two workers and takes approximately 1.5 to 2 hours to fill a reactor with a daily processing capacity of 12 tons. If an automatic feeder is not used, the entire feeding process will take 2-3 workers 3-4 hours to complete.

The second step is pyrolysis. After the feeding is completed, the burners need to be ignited to heat the plastic pyrolysis machine reactor. This will evaporate the water content in the waste plastic. The temperature will then gradually increase to 200 degrees Celsius. By controlling the burners to maintain the temperature between 230 and 260 degrees Celsius, the oil output stage is reached. Next is the constant temperature reaction stage, during which the temperature will decrease. It needs to be controlled to gradually increase until the oil output decreases. Finally, the temperature is raised to 150 degrees Celsius to ensure that the plastic pyrolysis fuel oil is fully extracted.

The third step is the condensation stage. DOING plastic pyrolysis machine includes a cooling system with four steps. It consists of two vertical condensers, one oil-water separator, two horizontal condensers, and two condensation towers. The first oil tank contains heavy oil that has been cooled down through the vertical condensers, while the oil in the second and third oil tanks will be of better quality. The two horizontal condensers have the largest cooling area and provide the best cooling effect, allowing for 80% - 90% of the oil to be cooled down. All condensers use circulating cooling water, achieving zero wastewater discharge. The uncondensed gas can be purified and used for heating the pyrolysis reactor.
