Total project cost


GCM Mandate

GCM performed a FEED study to define the project scope of the unit replacement, including the gas scrubber internals.


  • FEED report with detailed cost estimate
  • Metallurgical evaluation to avoid future cracking and corrosion problems.
  • Optimization of scrubber design and sizing
  • Constructability study
  • Preparation of 3D modeling in a brownfield environment
