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.
