Plastic Pyrolysis

Industrial-scale conversion of waste plastics into recovered pyrolysis oil.

What it is

Gangjin's PCP (Plastic-to-Chemical Pyrolysis) system converts mixed waste plastics — PE, PP, and PS — into recovered Plastic Pyrolysis Oil (PPO) through a controlled thermal decomposition process. Built on a modular architecture available in batch, semi-continuous, and continuous configurations, the system integrates Gangjin's proprietary A-Tower and S-Condenser technologies to ensure stable vapor recovery and consistent oil quality.

Technology & Engineering

A-Tower
Vapor Conditioning System

  • Proprietary vapor conditioning technology that stabilizes pyrolysis vapor before oil recovery.
  • Thermal cracking : controls heavier vapor fractions, improves downstream oil quality
  • Paraffin reduction : minimizes paraffin content from PE-derived hydrocarbons
  • Inline flash-point adjustment : supports PPO stabilization without separate equipment
  • Wax carryover control : reduces wax/heavy carryover to condensers, lowers plugging risk

S-Condenser
Oil Recovery System (patent-pending)

  • Proprietary condensation system engineered for stable PPO recovery and phase separation.
  • Stable vapor condensation for consistent liquid recovery
  • Efficient phase separation of oil, water, and sludge streams
  • Reduced entrainment : improves oil recovery stability
