Phenol Production Unit
The Phenol Production Unit is a critical facility in modern petrochemical complexes, producing phenol and acetone as high-value intermediates for downstream products such as bisphenol-A (BPA), polycarbonates, epoxy resins, phenolic resins, solvents, and specialty chemicals.
Commercial phenol plants are typically integrated with downstream resin and polymer units and are designed for continuous operation with high reliability.
The process is mature, globally licensed, and supported by proven equipment and catalyst systems.

Production Process Overview
Phenol is commercially produced using the well-established cumene process.
Co-production of acetone with strong market value
Integrated purification and recovery sections
Cumene Oxidation Route
Phenol is commercially produced using the well-established cumene process. In this route, cumene is oxidized to cumene hydroperoxide, which is then cleaved to produce phenol and acetone.
Key commercial features:
- Proven and widely licensed industrial process
- Co-production of acetone with strong market value
- High selectivity and stable long-term operation
- Integrated purification and recovery sections
This route dominates global phenol production due to its efficiency, scalability, and favorable economics.
