Waste plastic to fuel conversion pyrolysis plant

Waste plastic to fuel conversion pyrolysis plant is a new design that can convert waste plastic to fuel oil and carbon black.

The rapid rate of plastic consumption throughout the world has led to the creation of increasing amounts of waste and this in turn poses greater difficulties for disposal. Nowadays, the largest amount of plastic wastes is disposed of by land filling, and incineration. So, Environmental pollution increases day by day in everywhere. Plastic wastes are the main causes of environmental pollution.
Recycling has many types of techniques including pyrolysis, gasification,hydrolysis and etc. Among them, the most attractive technique of recycling is pyrolysis or thermal cracking.

Waste plastic to fuel conversion pyrolysis plan

The pyrolytic products can be divided into a gas fraction, a liquid fraction consisting of paraffins, olefins, naphthenes and aromatics, and solid residues.
The complex pyrolysis products may also be grouped as oil gases, liquid fuel and carbon black.
Mixed plastic wastes include HDPE, LDPE, PP, PS and ABS.
plastics were collected locally as used laundry bottles, shampoo bottles, soft drink bottles, water bottles,juices cups,various foam, shopping bags and plastic bags and so on.

Waste plastic to fuel conversion pyrolysis plant pyrolysis process:

Waste plastic to fuel conversion pyrolysis plant pyrolysis process

The necessary equipments for waste plastics cracking were mainly consisted of reactor, auto-feeder, catalyst chamber, oil water separator, condenser units, vacuum device, water, fuel container, combustion system, safety device, dedusting system, exhaust gas recycling system and operating system.

Reactor and condensers are significant role in pyrolysis process. The function of reactor is to break down the long chain hydrocarbon composed in various plastics. The reactor has been designed as a cylindrical shell for the solid waste pyrolysis. The condenser is provided to cool and condense the gases evolved out from the pyrolyser. As a result of cooling, the condensable gases become liquid which is called pyrolytic oil. The required units for reactors and condensers were constructed in the local workshop.

Introduction of main parts and features of waste plastic to fuel conversion pyrolysis plant
Reactor	1. Made by Q245R boiler plate. Also can choose Q345R, OR 304 AND 306 stainless.

	2. Auto-welding both inside and outside

Auto-feeder	1. 60 ton hydraulic pressure

	2. Can feed all types of materials

	3. Save labor and save time

Catalyst chamber	1. Improve oil yield and oil quality

	2. Reduce the speed of oil gas so that it can be better cooled
Oil-water separator	1. Separate oil and water

	2. Collect heavy oil

	1. Water sealing design keep safety
Condenser	1. The oil gas is cooled separately by small pipes inside condenser

	2. Light oil is collected here
Vacuum device	Keep machine running under normal pressure
Anti-back fire device	1. Recycle residual gas to furnace as fuel

	2. Water sealing design prevent tempering
Dust removal device	Dispose of flue gas caused by using coal, wood, oil or natural gas.

The product yield such as oil, gas and carbon black from pyrolysis process:

1.Fuel Oil (40% to 45%)

Fuel oil application

The main application of oil products produced by plastic to fuel conversion pyrolysis plant is the fuel oil that is wide used for industrial and commercial purposes. Such as power plant factory,glass factory,cement factory,ceramic fatory.
Exhaust gas (About 10%)
We get about 10% pyrolytic gases during pyrolysis process. The main component of this gases are methane (CH4), so we can not condense and store this gases. We use this gases to heat the reactor and we can use exceed gases for other heating application.
Carbon Black (30% to 35%)

Carbon black application

The second product of waste plastic to fuel conversion pyrolysis plant is carbon black. The quantity of carbon black is about 30% to 35% according to tyre quality. Carbon black can application to electric cable jacketing,black nylon bag,rubber additive.
