Abstract：
Post-Combustion Carbon Capture (PCC) using amine based solvents in integrated absorber-stripper column systems currently represents the only credible means of implementing carbon capture and storage (CCS) on a commercial scale in the time frame required to reduce CO2 emissions globally. Aqueous amines, e.g. MEA, have been applied to CO2 capture/separation in the oil and natural gas industries for decades and are promising solvents for removal of CO2 from flue gases. However, the application of aqueous amines in CO2 capture from flue gases still has many challenges such as high energy penalty for CO2 capture, absorbent degradation, facility corrosion and environmental issues. CSIRO PCC team has carried out researches in a wide range of science and technology areas from laboratory studies and pilot plant trials to develop efficient and applicable amine absorbents and process. The CSIRO chemical sorbent program has achieved significant progress in amine absorbent development via smart formulation and specific amine design and synthesis based on enormous amine property and reaction characteristics studies.
Introduction：
Dr Qi Yang is a senior research scientist with CSIRO Manufacturing Flagship in Clayton, Australia. She is also an Adjunct Professor at Hunan University, China. Qi obtained her PhD degree in organic chemistry from Monash University, Australia. Her research in CSIRO has covered a wide range of areas including natural product isolation, total synthesis of natural product, drug discovery and pesticide development, clinical trial drug synthesis (GLP) and absorbent development for CO2 capture. She has developed expertise in understanding the impact of compound structures on their chemical reaction behaves and capacity to design and synthesis molecules to meet their application needs. She has applied and improved NMR technology to amine speciation study in aqueous solutions and this method has been widely adopted by other researchers in this research area. She has also led intensive study to understand impacts of amine structure on amine performance in CO2 capture process and built up a library of amine characteristics in CO2 absorption and desorption. She has designed specific amines to improve energy performance of amine absorbents in CO2 capture. Dr Yang has led projects in natural products and in target amine compound design, synthesis for CO2 capture.
