The modifications to the existing site to accommodate the rerouting of the flare gas included:

  • Process tie-in selection
  • 2 stage dry screw compression with water injection
  • Interstage KO vessels and VSD driven air coolers
  • Replacement of flare seal vessels
  • Level instruments and control valves
  • Siemens control and safety systems PLC

Costain designed the process modifications to the refinery and was awarded the EPC contract. As part of the construction, additional tie-ins were made to accommodate future flare gas recovery.
