Results from Trialling Aqueous NH 3 Based Post Combustion Capture in a Pilot Plant at Munmorah Power Station: Desorption

Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO) and Delta Electricity have tested an aqueous ammonia based post combustion capture (PCC) process in a pilot plant at Munmorah black coal fired power station. This paper presents and discusses the experimental results obtained and primarily focuses on the desorption section.

26 – Pilot plant operation for liquid absorption-based post-combustion CO2 capture

Pilot-scale operation is often used when developing new technologies or processes for commercial application. It allows collation of realistic operating and engineering data at a smaller scale, and hence a smaller cost, than would be achieved at a full-size facility. Liquid absorbent-based removal of CO2 from process gas streams is not a new technology, having been used in applications such as natural gas processing. However, it has only recently been used to treat combustion flue gases. Research and commercial organizations worldwide have now constructed and operated pilot-scale post-combustion CO2 capture facilities operating on both synthetic and real combustion flue gases. This chapter considers the design and operation of these facilities, and also reviews the results achieved at several CO2 capture pilot plants.
