As an important basic material, plastic can be found everywhere in our daily lives. The essence of plastic pollution is that plastic waste enters into the environment, such as waste, soil, and so on. Because of its difficulty of degradation, it brings about visual pollution, soil destruction, microplastics and other environmental hazards.
Plastic pollutants have certain resource properties while causing pollution. The pyrolysis of plastic waste is an advanced method to slove the plastic pollution. It is not only effective in reducing plastic pollution, but also produces fuel oil.
How To Produce Pyrolysis Oil By Waste Plastic Pyrolysis Machine?
Firstly, we need a set of waste plastic pyrolysis equipment. Niutech has been dependentaly research and development industrial continuous waste plastic pyrolysis equipment for more than 30 years.
Secondly, the prepared plastic waste is feeded into a pyrolysis reactor vessel continuously. The reactor is sealed to create an oxygen-free environment. The temperature inside the reactor is then raised to the pyrolysis temperature, typically in the range of 400°C to 500°C, depending on the type of plastic being processed.
As the plastic waste is heated, it undergoes a chemical transformation, causing the plastic to break down into small molecule monomers, dimers, etc. These substances are then polymerized into a variety of olefins. The oil gas is condensed into oil through the cooling system, which is pyrolysis oil.
There are many types of plastics. PE/PP/PS plastics, ABS engineering plastics, plastic cable skins, plastic household waste, medical waste, paper mill scraps, etc. can be used for oil refining. Different types of plastics have different oil yield rates. The overall range is 40-95%. For example, the oil yield rate of pure PE plastic can be as high as about 95%; that of pure PP/PS plastic is about 90%; that of pure ABS plastic is about 40%, etc.
Utilizing Waste Plastic Pyrolysis Oil
Pyrolysis oil is a liquid product that can be used as chemical raw material, and further refined to make synthetic resins, which in turn can be used to make new plastic products.
Beseides, waste plastic pyrolysis oil can directly used as fuel, it can also be hydrotreated to obtain gasoline and diesel fuel fractions, replacing traditional crude oil, realizing energy substitution.
From 1950 to 2017, a total of 9.2 billion tons of waste plastics were produced globally. Approximately 7 billion tons became plastic waste. Even now, only about 9% of plastic waste has been recycled; millions of tons of plastic waste are discarded into the natural environment, either in landfills or transported to fixed sites for incineration or dumping.
Equipment for pyrolysis of plastics to fuel is an advanced scientific method for solving plastic pollution with both environmental and economic benefits, and it is a technology and method that deserves to be popularized globally.
Niutech has been focusing on the R&D and manufacturing of waste pyrolysis technology and equipment for more than 30 years, realizing the great initiative of “turning waste into wealth” .
Niutech waste pyrolysis technology and equipment have been successfully applied to many projects at home and abroad. In Thailand waste plastic and waste tire pyrolysis project, the plastics are pyrolyzed by Niutech’s pyrolysis equipment to obtain high-quality fuel fractions and combustible gases. Through further processing, diesel or refinery feed oil can be obtained, which is used used as fuel for the company’s vehicles.
