- Feedstocks
- Method 1.) Ethylbenzene + Superheated Steam or Hydrogen Peroxide
- Method 2.) Toluene + Methanol
- Processing
- Addition of Polymerization Inhibitors for Processing + Storage of the Styrene
- (Fractional) Distillation
- Polymerization Reactor along with Water and Radical Initiator / Polymerization Initiators (more Terminology Hell )
- Drying (Via Hydrocyclone and/or Centrifuge then Hot Air? (With Effluent Recovery + Recycling / Industrial Wastewater Treatment and Flue Gas Scrubbing
