CO2 Capture

GLP designs and supplies process plants for the capture, processing, liquefaction and storage of carbon dioxide (CO2).

GLP employs a dedicated team of multi-disciplinary engineers and designers who have broad experience in the design, fabrication, installation and commissioning of modular process plants for the Carbon Capture and Storage (CCS) Industry.

GLP’s project experience includes the capture and processing of CO2 from both lean and rich sources from coal fired and gas fired steam boiler plant, natural gas on-shore treatment plant and hydrocarbon industry steam reformer plant.  CO2 capture from fermentation plant has also been studied.

Examples of GLP process plant used at the various stages of carbon capture include:

  • Hot flue gas quenching, SO2 removal and gas filtration plant.
  • CO2 absorption and stripping utilising amine solvents such as MEA (Mono-Ethanol-Amine) for lean CO2 gas streams and aDMEA (Activated Di-Methyl Ethanol-Amine) for CO2 rich gas streams.
  • CO2 stripper off-gas compression using reciprocating, screw and multi-stage turbo machines.
  • Adsorption plant for removal of trace H2S, COS and organic sulphides.
  • Catalytic oxidation plant for removal of trace hydrocarbons, alcohols, aldehydes and ketones.
  • Dehumidification and final drying plant.
  • CO2 liquefaction by low temperature refrigeration
  • Distillation of liquid CO2 to remove trace air gas (O2 and N2)
  • Adsorption plant to remove trace NOX from liquid CO2
  • Low temperature storage of Liquid CO2
  • Road tanker loading and un-loading stations for importing and exporting liquid CO2

Plant capacities range from 10 to 500 MTPD of CO2.

Product purity meets or exceeds food grade specifications imposed by all internationally recognised beverage manufacturers and Australian and New Zealand food standards authorities.

GLP designers utilise the latest hydraulic and process modelling techniques with 3-dimensional modelling to optimise plant designs.  This ensures GLP plants are cost competitive, energy efficient, easy to operate at all levels of turn-down, reliable and maintainable.
