Carbonylation F&E project

Design, manufacturing and installation of ThermFlex® heat exchanger for Carbonylation project in the Coal to Ethylene glycol process


  • Application: Heat exchanger of Carbonylation Reaction in the Coal to Ethylene glycol process
  • Plant: Inner Mongolia
  • Country: China
  • Customer: ECO
  • Media shell side: Effluent-recycle gas
  • Media lamella side: Feed-recycle gas
  • Design pressure: 6.5/6.5 bar
  • Design temperature: 185/185 ℃
  • Material plate bundle: AISI304
  • Material shell: Q345R+AISI304L

The challenge
Large flow rate (200 000 kg/h), low total pressure drop (< 60 kPa)

The solution
Continuous and stable operation Parameters such as pressure drop in actual operation meet the design requirements
