Post Combustion Capture (PCC)
Advancing innovative flue gas scrubbing technologies to industrial maturity in collaboration with strategic partners.
CO2 flue gas wash unit (pilot plant); Operator: RWE Power AG; Location: Niederaussem, Germany

Addressing Growing Need for Carbon Capture from Flue Gases

Post combustion capture (PCC) is a good way for customers to capture CO2 from flue gas streams and ensure compliance with increasingly strict emissions thresholds. With this technology, CO2 is separated from the flue gas by scrubbing with a chemical solvent such as amine. We have long-standing experience in the design and construction of chemical wash processes, providing the necessary amine-based solvent systems and the CO2 compression, drying and purification system. In addition, we team up with strategic partners such as BASF to provide one-stop, end-to-end solutions.

Highlights of our PCC offering:

  • Quick realization from planning to operation
  • Compact footprint
  • High CO2 capture rate, even at low CO2 concentrations
  • Reduced solvent degradation
  • Unique emissions control technology with minimum environmental impact
  • Optimized total cost of ownership

Teaming Up to Drive Innovation in Carbon Capture

To meet the growing need for carbon capture, RWE Power, BASF and Linde partnered and joined forces to develop and advance PCC technologies. This alliance bundles our strengths and proven track record in the design and delivery of turnkey industrial plants with BASF’s leading role in high-performance gas treatment technologies for carbon capture. Under its OASE brand*, BASF developed a range of high-performance gas treatment technologies. The BASF OASE® process is used successfully in more than 400 plants worldwide to scrub natural, synthesis and other industrial gases. With OASE blue, BASF developed a technical solution specifically for PCC. The OASE blue package includes an aqueous amine-based solvent which is highly stable.

BASF and Linde decided to demonstrate this technology at two pilot plants based at RWE Power, Niederaussem (Germany) and NCCC, Wilsonville/AL (USA). The operational experiences gained at these pilot plants has confirmed the technical readiness of this technology for industrial scale. It is ideally suited to a range of industries including coal-fired power plants, gas turbine applications and waste incineration.
