 FAQ

Q1: What is the quality and application of the pyrolysis oil?

A1: The oil is high-quality with wide applications. Efficient quenching and three-phase separation yield oil high in light components and calorific value, with low impurities. It serves as industrial fuel, can be refined into non-standard diesel, or used as petrochemical feedstock for olefin production.

Q2: How does this differ from waste tire pyrolysis?

A2: Both use oxygen-free pyrolysis, but differ due to feedstock. Waste plastics require specialized feeding and anti-coking systems due to low density, varied forms, and potential chlorides. Tire pyrolysis focuses more on steel wire separation.

Q3: Can the equipment handle complex mixed plastics and meet environmental standards?

A3: Yes. The equipment is designed for complex mixes from various sources. Combined flexible sealing creates an oxygen-free environment, preventing dioxin formation. A multi-stage flue gas purification system (deacidification, dust removal, adsorption) ensures emissions meet stringent national and international (e.g., EU) standards.
