Pyrolysis Oil From Plastic Waste
2015-09-16
At present, recycling plastic into pyrolysis oil is widely recognized as a good way to solve the
problems of plastics pollution and energy shortage. That’s because the pyrolysis oil from plastic
waste can be widely used as fuel oil in industries such as steel and iron and boiler factories,
ceramics, power or chemical industries etc, and they can be also refined into diesel or gasoline
by waste oil distillation plant. And the diesel fuel can be used in the low speed engine, such as
digging machine, road roller, loading machine etc.
Pyrolysis
Oil From Plastic Waste
Now let’s take a look at the details of the waste plastic to oil pyrolysis process. The following is the
working process of a continuous plastic pyrolysis plant:
1. First, waste plastic needs to be broken into small pieces by the crusher. If the water percentage of
plastics is more than 15%, then they need to be dried by a dryer. Through the automatic feeding
device, the pre-treated plastics are transported to the reactor.
2. Heating the reactor by using fuel materials, such as coal, charcoal, fuel gas, wood etc. The
reactor will be slowly heated, when the temperature reaches around 250 degrees, the oil gas will be
produced.
3. A part of oil gas will go to the condensing system to be liquid oil. The gas which can not be
liquefied under normal pressure will go back to combustion system. It can replace the fuel material to
heat the reactor, which will save energy for the whole plastic pyrolysis process.
4. After finishing oil production, the temperature of plastic pyrolysis reactor will be down. At the same
time, the carbon black will be discharged automatically.
5. Lastly, the smoke produced from reactor can achieve national emission standard after being
processed by the dedusting system.
Output Rate of Pyrolysis Oil From Plastic Waste:
1. Polyvinyl chloride PVC, polyethylene: PE (such as films, bottles, electrical insulating materials,
handbags, pipes, drums, bottles/calcium bottles, daily necessities, etc.) pure plastic has oil yield is
about 95%.
2. Polypropylene: PP (such as films, plastic rope, tableware, pots, barrels, furniture, bags, caps, car
bumpers, etc.) of pure oil yield 90%.
3. PS (such as electrical appliances, stationery, cups, food containers, appliance housings, electrical
fittings, foam products, toys, etc.) of pure oil yield at 90%.
4. ABS plastic: 40%.
5. Pure white plastic sheeting: about 70%.
