CDRMax Process Description

CDRMaxTM patented technology enables > 90 % CO2 capture from the feed flue gases. The key process steps are:

  • Flue Gas Conditioning System
    • The flue gas is conditioned by an SO2 removal step in combination with a cooling of the gas
  • Absorber Column
    • The flue gas enters the absorber column for CO2 absorption.
    • The height of the absorber and packing sections allows for sufficient contact time between the flue gas stream and the counter-current proprietary solvent flow, resulting in efficient CO2 absorption
  • Washing Section
    • The depleted flue gas exits the absorber column and passes through an integrated water washing section to minimize the loss of the solvent
  • Stripper Column
    • The CO2 rich solvent from the absorber bottom flows to the lean/rich heat exchanger, where the rich solvent is heated before entering the stripper column.
    • The lean solvent (low CO2) flows to the re-boiler, where it is heated by auxiliary steam. The steam from the re-boiler enters the stripper tower flows upward, counter-current to the rich solution.
    • The absorbed CO2 is released from the rich solvent and flows to the top of the stripper tower. The lean solvent is returned to the absorber column via the lean/rich heat exchanger for further flue gas processing
  • The captured CO2 is directed for end-use application
