If you are engaged in waste recycling, you may know the plastic to oil conversion technology. It is generally known as pyrolysis. What is pyrolysis? It refers to a thermal decomposition of materials at elevated temperatures in an inert atmosphere. If you put plastic (PET and PVC are not including) in such an atmosphere (usually high-temperature and oxygen-free), you will get liquid oil from the plastic with the help of this technology.
When and Where Can It Be Used?
This waste plastic to oil conversion technology can be used in the waste recycling organizations, companies or factories. They have enough financial strength and technical support to invest in a large plant that adopts this technology to get oil from plastic waste. In addition, if you have a large number of plastic waste to dispose of and also want to reuse the waste, the plastic to oil technology is also a choice for you. Because of the wide uses of the oil, it will be a profitable investment project.
Description of the Plastic to oil Process
The conversion of waste plastic to oil includes 4 main steps: heating, oil gas generation, condensing and oil discharging.
- Firstly, you need to heat the plastic waste in a sealed and oxygen-free pyrolysis reactor.
- When the inner temperature reaches to 160℃, oil gas will be generated.
- And then the gas will be separated by a manifold according to the particles in it.
- The heavy particles in the gas will be liquefied into heavy oil and the light oil gas will rise up to be condensed into light oil. The light oil will be reserved in the light oil tank and it is the final oil you get from plastic.
|Types of Plastic||Oil yield|
|Pure white plastic sheeting||60%-70%|
|Fishing net, safety net||45%-50%|
|Bags of instant noodles||40%|
|Pure plastic cable||60%-80%|
|Clean plastic bags||50%|
Is The Plastic to Oil Conversion Technology Safe to Use?
Technically, it is quite safe if you are professional enough to use it. The application of this technology is not only a simple conversion process of plastic to oil, but a large engineering project. You cannot be too careful while using it. For example, you should choose the right catalysts (activated clay, ZnO and barium hydroxide are acceptable) and you need to watch the temperature change in each phase of the conversion.
Environmentally, you should also pay attention to the byproducts of this conversion. Except for the oil, there are also carbon black and combustible gas generated. Carbon black can be an industrial material so it needs a proper reservation. The combustible gas can be dangerous without a proper disposal. With the plastic to fuel machine for sale in Beston, you are able to collect the combustible gas and then reuse it as the fuel to heat the pyrolysis reactor.
There will also be some residual gas during the conversion of waste plastic to oil. The gas is usually sulfurated and harmful to the air, thus, a professional filtering system will be a good solution to avoid the environmental pollution. So we suggest a system with a spraying tower to cleans, a de-dusting and desulfuration system, ceramic ring adsorption and activated carbon absorption to make sure a safe emission.
In a word, the plastic to oil technology is a new green technology which can generally be used in the plastic recycling industry. With an increasing number of plastic materials, this technology will be more needed and play an important role in waste recycling.
As a professional plastic pyrolysis plant manufacturer, Beston well applies the plastic to oil conversion technology to our plants and helps a lot of people with their plastic waste disposal all over the world. If you have any question about this technology, Beston will here for answering your question at any time.
