Features
① Plastic-oriented anti-coking pyrolysis process for plastic melting characteristics
Targeting plastics' tendency to melt and form coke under heat, the plant applies low-temperature segmented temperature-controlled pyrolysis. Polymer chain cracking and oil-gas release take place within the optimal temperature window. It avoids heavy-component accumulation and inner-reactor coking triggered by instant high-temperature pyrolysis. The pyrolysis-oil yield rises by 10%-15 % compared with general-purpose pyrolysis equipment. Continuous operation cycles are greatly extended and coke-cleaning maintenance frequency is reduced by over 70 %.
② Integrated raw-material pre-treatment design for high-impurity waste plastics
Customers may optionally purchase the matching integrated pre-treatment unit. It completes crushing, washing and drying in one workflow to remove surface sediment, contaminants and moisture from waste plastics. It solves poor-oil-quality and condenser-blocking risks caused by direct pyrolysis of heavily contaminated plastics and greatly broadens acceptable feedstock varieties.
③ Recyclable combustible-gas system for energy self-sufficiency
Non-condensable gas generated from plastic pyrolysis is purified and fully fed back into the combustion chamber as heating fuel. Over 90 % of heating energy can be self-supplied. Only a small volume of external fuel is required for cold-furnace startup. Consumption of coal, natural gas and other external fuels is significantly cut down, lowering routine operating expenses effectively.
Advantages
① Broad feedstock compatibility to handle mixed waste-plastic streams
Besides clean single-grade waste plastics, the plant processes mixed waste plastics sorted from municipal-solid-waste facilities, plastic-manufacturing off-cuts, waste packaging films and agricultural mulch films containing impurities. Strict plastic sorting is not mandatory, which greatly reduces raw-material procurement and pre-treatment costs and diversifies feedstock sources.
② Stable oil quality with good market acceptance
Benefiting from anti-coking technology and multi-stage anti-clogging condensation, the produced pyrolysis oil features low impurity content, stable calorific value and good fluidity. It can be directly sold as fuel oil for industrial boilers, kilns and generators without extra refining. It enjoys extensive market channels and strong bargaining power. The comprehensive profit per ton of waste plastic increases by more than 18 % versus universal pyrolysis units.
③ Complete eco-friendly configurations to satisfy strict emission standards
Full-process sealed negative-pressure design is adopted, with sealed collection and flame-arresting components installed at all oil-gas junctions to eliminate oil-gas leakage. Standard-equipped complete flue-gas desulfurization, denitrification and dust-removal units provide targeted treatment for organic waste gas, sulfides and nitrogen oxides produced during plastic pyrolysis. Flue-gas readings are far below national and local environmental limits. It operates smokeless and odor-free, supporting smooth EIA approval and long-term compliant production.
④ High-level automation cutting labor and maintenance expenditure
Full-process automatic operation covers raw-material pre-treatment, feeding, pyrolysis temperature regulation, oil-gas condensation and slag discharging. Only 4-6 operators are required for one complete batch, which eases manual workload and labor costs. Anti-coking and anti-clogging structures minimize equipment failure rates and maintenance frequency for low long-run upkeep costs.
⑤ Short payback period with controllable project risks Waste plastics are widely available at low procurement cost, while pyrolysis oil maintains steady market demand. Supported by high energy self-sufficiency and low operating costs, the standard 10-ton-per-day plant running 300 days per year generally achieves a payback period of 10-14 months under regular market conditions. Where local solid-waste-disposal subsidies or green-tax incentives apply, payback can be further shortened to 8-12 months, delivering stable returns with low investment risk.
⑤ Full-process sealed eco-friendly design for cross-region compliant operation The plant adopts full-process sealed negative-pressure pyrolysis design and is standard-equipped with complete flue-gas desulfurization, denitrification and dust-removal systems. It runs smokeless and odor-free. Configurations can be quickly adjusted according to environmental-protection standards of different countries and regions to meet local emission requirements. It can operate compliantly across regions without environmental-compliance concerns.

Production Process Flow
- Raw-material Pre-treatment: Waste plastics go through manual sorting to remove non-pyrolyzable foreign substances. They are fed into plastic shredders, then washed to eliminate sediment and stains, and dried to remove moisture. Clean shredded plastic stock is obtained and stored temporarily in the raw-material silo.
- Feeding into Reactor: Shredded plastic from the silo is delivered into the pyrolysis reactor via sealed feeding devices. The feeding port is fully closed and sealed after charging to guarantee an air-tight reactor environment.
- Segmented Temperature-controlled Pyrolysis: The combustion chamber ignites for heating. While rotating, the reactor follows pre-set multi-stage heating profiles: low-temperature phase for plastic melting, dehydration and softening; medium-temperature phase for polymer-chain cleavage and oil-gas release; high-temperature phase for thorough decomposition of carbon residues to secure sufficient pyrolysis.
- Oil-gas Dust Removal & Condensation: Oil-gas generated from pyrolysis passes through the gas-drum to remove entrained dust contaminants. It flows into the spray scrubber for further purification and then enters multi-stage tubular condensers. Forced circulating-water cooling enables fast heat exchange and liquefaction. Liquid pyrolysis oil flows into oil storage tanks; non-condensable gas enters the combustible-gas purification system.
- Combustible-gas Recycling: Purified non-condensable gas passes through flame arrestors and feeds into the combustion chamber as heating fuel to substitute external energy sources and realize on-site energy self-sufficiency. Surplus combustible gas can be collected and stored for other on-site energy demands.
- Cooling & Slag Discharge: Heating stops upon completion of pyrolysis. The reactor keeps rotating for accelerated cooling. When furnace temperature drops to a safe level, carbon-black residues are discharged via sealed slag-removal devices, cooled down and collected for direct sale as finished goods.
- Flue-gas Purification & Discharge: Flue gas exhausted from the combustion chamber undergoes deep treatment in desulfurization towers, dust collectors and denitrification units. It is released through chimneys after reaching emission standards. The whole workflow runs smokeless and odor-free to satisfy environmental-protection requirements.
- Product Storage & Sales: After passing inspection, pyrolysis oil stored in tanks and collected carbon black can be sold directly, completing the full-chain resource recovery of waste plastics.
