Targeted PPO Polishing
Selectively removes critical contaminants from raw plastic pyrolysis oil
Low‑CAPEX and OPEX
Low utility complexity enables decentralized, small‑scale pyrolysis plants
Improved Downstream Compatibility
Produces polished PPO suitable for refinery and petrochemical co‑feeding
PyroCare™ Targeted Polishing
Sulzer’s advanced purification technologies transform raw plastic pyrolysis oils into premium hydrocarbon feedstocks.
By efficiently removing contaminants like sulfur, nitrogen, chlorine, and oxygenates, we enable pyrolysis oils to be used as high-quality fuels and chemical building blocks supporting true circularity in the plastics industry.
Main benefits
Lower capital and operating cost pathway to higher‑value PPO: PyroCare™ enables targeted contaminant removal without complex utility integration, reducing CAPEX while upgrading raw PPO to higher‑value polished oil
High flexibility for small to medium pyrolysis plants: Modular design and low utility requirements make PyroCare™ viable for decentralized and smaller‑capacity pyrolysis operations
Improved downstream acceptance and market access: PyroCare™ produces polished PPO compatible with refinery and petrochemical co‑feeding, reducing risk and expanding blending options
Key characteristics
Targeted PPO polishing: Selective polishing of plastic pyrolysis oil like Cl and Si based on contaminant profile
Advanced separation technology: Proprietary Kühni agitated column ensures robust mass transfer performance and feedstock variability
Proven contaminant removal: Demonstrated high removal of chlorides, nitrogenates, oxygenates, and silicon

Pyrolysis oil is a crude oil-like product obtained by chemically decomposing mixed plastic waste at high temperatures in the absence of oxygen. It contains a mix of hydrocarbons and impurities that require purification.
Pyrolysis oil contains impurities such as sulfur, nitrogen, chlorine, oxygenates, and halogens, which must be removed before the oil can be used as fuel or chemical feedstock in downstream processes.
Sulzer provides modular solutions including quenching, hydrotreating, fractionation, BTX recovery, and wax/oil separation all designed to turn mixed plastic pyrolysis oil into high-quality, purified hydrocarbon streams.
Sulzer’s technologies can recover naphtha, diesel, aromatics (BTX), waxes, and other valuable hydrocarbons each suitable for use as fuel or as feedstock for new plastics and chemicals.
By transforming mixed plastic waste into high-purity hydrocarbons, Sulzer enables true closed-loop recycling, where waste plastics are turned back into high-quality products equivalent to virgin materials.
Sulzer’s modular and skid-mounted units offer flexibility, fast deployment, and proven performance, allowing customers to adapt to different feedstocks and maximize the value recovered from plastic waste.
