Description

 

A generic phosgene production technology is provided based on the upper level phosgene process description for whenever the actual technology employed is not known.

Steps and pieces of equipment (units) for the Simplified Phosgene Process Flow Diagram in the illustration:

  • Feed: High-purity, dried CO and Cl2.
  • Mixer: Inline or packed bed mixer for even gas distribution.
  • Primary Reactor: Fixed bed of activated charcoal (typically coconut shell type).
  • Secondary Reactor: Completes conversion and manages temperature profile
  • Condenser & Separation: Cools product, condenses phosgene, vents to absorber.
  • Wash Columns & Distillation: Removes residual Cl2, HCl, and byproducts, distills final product
  • Caustic Scrubbers: Destroy residual phosgene by NaOH neutralization; incinerator or activated carbon beds as end-of-pipe controls.
