Plastic pyrolysis converts plastic waste into pyrolysis oil, gas and residue.
Depending on quality of plastic waste, the typical yields from plastic pyrolysis are:
Pyrolysis oil : 50 to 80% - variable depending on the type and percentage of plastic present in plastic waste
Pyrolysis gas : 20 to 35% - variable depending on the type and percentage of plastic present in plastic waste
Pyrolysis residue : 3% to 30% - variable depending on ash content and soil content in the plastic waste
Wastewater : if there is moisture content in plastic waste, waste water will be generated.
All plastic waste is not the same. Depending on the source, the quality of plastic waste varies a lot with respect to plastic composition, moisture content and content of non-plastics. Variation in plastic waste quality results. in variation in pyrolysis oil quality and yield. APChemi's Pyrolysis Oil Purification Technology helps produce similar quality of PyOil even though the plastic raw material quality varies due to factors beyond control.

Pyro = Heat & Lysis = Breakdown.
Plastic Pyrolysis reaction involves the molecular breakdown of larger plastic molecules into smaller molecules of oil gas and carbon using heat. Pyrolysis is also known as thermal cracking, cracking, thermolysis, depolymerisation, etc. It can also be called catalytic pyrolysis when catalyst is used.

Q: What are the Key Performance Indicators (KPIs) for selecting plastic pyrolysis technology?
A: KPIs are:
1. Safety First: During the pyrolysis process, flammable materials are heated to an explosive temperatures. Slight negligence can lead to hazard and injury. We, at APChemi understand: Total Safety = Equipment Safety + Human Safety + Process Safety.
Unlike the most 'hot-pot type barbecue reactor technologies', APChemi offers standard pyrolysis plants for robust and safe pyrolysis.
2. Energy Efficiency: The energy efficiency of the plant decides the profitability of the pyrolysis operation. Energy recovery is an integral part of APChemi's Pyrolysis Plant. Highly energy efficient Pyrolysis Reactor designed by APChemi ensures maximum pyrolysis efficiency at the lowest possible temperature and heat load.
3. Feedstock Flexibility: APChemi's pyrolysis plant can process solids, semisolids, waxes, and liquids. You can process plastic, tire, biomass and waste oils - all in the same reactor. You can feed high-density raw material and low-density raw material. We understand that technology needs to be agile so as to accommodate variations in feedstock composition

What safeguards do you have on your waste tyre pyrolysis ...
What safeguards do you have on your waste tyre pyrolysis plant?
The most important thing for a customer who wants to buy waste pyrolysis plant is whether the plant has high safety protection measures or not. As a reliable waste tyre pyrolysis plant manufacturer and supplier, what our customer worries will be what we are most concerned about.
The waste tire pyrolysis process is completed in a production line which is composed of different parts with different functions rather than a single machine or any independent equipment. When we design the technical process of our waste pyrolysis plant, we will consider the design of each part and make sure each of it can work for safety protection. And some safety devices independently developed by our engineer team have won the patent certificate.
A complete waste tire pyrolysis plant includes feeding system, pyrolysis system, cooling system, syn-gas purification system, syn-gas recycling system, flue gas scrubbing system as well as safety protection devices, so that the whole tire pyrolysis plant will comply with all health and safety, and environmental regulations in most areas of the world.
Here is a brief introduction of our waste tire pyrolysis plant for you to well know the general function of each part and what safeguards we have on our waste tyre pyrolysis plant.

Function
1
Waste pyrolysis system
The pyrolysis system is the core part of the waste tire pyrolysis plant, which is composed of reactor body, outside 360°covered insulation, reactor cooling system(after pyrolysis) as well as transmission system. Waste tire pyrolysis carris out inside the pyrolysis reactor.
Our pyrolysis reactor to made strictly according to pressure vessel in order ensure the pyrolysis process going under high safety protection.2
Cooling system
Adopt 4 -step cooling, each step cooling uses an independent cooling water circulation system to fully guarantee the cooling effect, and then ensure the oil yield. Among them, the oil-water separator not only plays the role of oil gas cooling, it is mainly used as the first safety device--water seal in the cooling system, to prevent the backflow of oil gas, and also to clean the carbon black powder contained in the gas in the late pyrolysis process.

Safety protection water sealTwo water seals working together to prevent the back -flow of tail gas.4
Temporary oil storage tank3 oil tanks are used to mach the 4-step cooling system, so that the heavy oil and light oil can be stored separately, not only improving the fuel oil quality but also preventing the cooling tube jam caused by heavy oil(gas).5
Water film flue gas dedusting system
1.Three -layer perforated strainers filter the flue gas with special chemical.
2. use high-pressure hydraulic pump to press water into high pressure nozzle which atomize the water to clean the smoke from furnace.6
Safety protection Vacuum systemEliminate the remaining oil and gas in the furnace to ensure the safety of on-site production operations, which can quickly cool the reactor and improve production efficiency.7
Feeding system50 tons of hydraulic propulsion to improve feed efficiency (two reactors can share one)
With auto-feeder, our customer can do the tyre feeding when the pyrolysis reactor is still hot , which can protect workers from scald.8
Syn-gas purification system
Remove hydrogen sulfide, sulfur dioxide, sulfur trioxide, nitrogen dioxide and other odorous polluting gases contained in the exhaust gas before combustion.9
Pyrolysis carbon black discharging systemSide slag discharge method to lift tire carbon black and discharge it in a sealed environment.
Besides, there are sufficient safety protection instruments like pressure gauge, temperature gauge, safety bell and safety valves, etc. Once the pressure inside the reactor exceeds the set value, the safety valves can work automatically to release the pressure.
Till now, our waste tire pyrolysis plants have been hot sale in 90+ countries and regions and work safely and stably. If you has requirements of waste tyre pyrolysis plant, just feel free to consult us for machine details and favorable quotations.
