A life cycle assessment study of a hypothetical Canadian oxy-fuel combustion Carbon Dioxide Capture process
International Journal of Greenhouse Gas Control, 2014Co-Authors: Jarotwan Koiwanit, Anastassia Manuilova, Malcolm Wilson, C. W. Chan, Paitoon TontiwachwuthikulAbstract:Abstract For at least the next few decades, fossil fuels will be used to supply energy globally, and without a proper control technique, Carbon Dioxide (CO 2 ) atmospheric emissions will continue to increase and pose an even more serious threat to human and environment. Therefore, the use of an effective Carbon Dioxide Capture technology has become important in ensuring reduction of CO 2 emissions. However, more raw materials and energy are required for the CO 2 Capture systems operation. Consequently, it is necessary to evaluate the environmental performance of the complete life cycle of the CO 2 Capture process in order to fully understand its environmental impacts. This study presents a life cycle assessment study on a hypothetical oxy-fuel combustion CO 2 Capture system in Saskatchewan, Canada. The study analyses the oxy-fuel Carbon Dioxide Capture and compares it with the lignite coal fired electrical generating station that has no Capture system. TRACI, the life cycle impact assessment (LCIA) method, is used to convert life cycle inventory data into environmental impacts. The observed results include a reduction in global warming and emissions to air impact categories due to Capture of particulate matter (PM), trace elements, CO 2 and acid gases. However, the emissions Captured would eventually leach to soil and then to the ground water when landfilled. Thus, an increase in the impact categories associated with soil and water was also observed.

A life cycle assessment study of a Canadian post-combustion Carbon Dioxide Capture process system
International Journal of Life Cycle Assessment, 2014Co-Authors: Jarotwan Koiwanit, Anastassia Manuilova, L Piewkhaow, Malcolm Wilson, Q. Zhou, C. W. Chan, Paitoon TontiwachwuthikulAbstract:Purpose: While Carbon Dioxide Capture and storage (CCS) has been widely recognized as a useful technology for mitigating greenhouse gas emissions, it is necessary to evaluate the environmental performance of CCS from a full life cycle perspective to comprehensively understand its environmental impacts. The primary research objective is to conduct a study on life cycle assessment of the post-combustion Carbon Dioxide Capture process based on data from SaskPower's electricity generation station at the Boundary Dam in Saskatchewan, Canada. A secondary objective of this study is to identify the life cycle impact assessment (LCIA) methodology which is most suitable for the assessment of Carbon Dioxide Capture technology integrated with the power generation system in the Canadian context. Methods: The study takes a comparative approach by including three scenarios of Carbon Dioxide Capture at the electricity generation station: no Carbon Dioxide Capture ("no Capture"), partial Capture ("retrofit"), and fully integrated Carbon Dioxide Capture of the entire facility ("Capture"). The four LCIA methods of EDIP 97, CML2001, IMPACT2002+, and TRACI are used to convert existing inventory data into environmental impacts. The LCIA results from the four methods are compared and interpreted based on midpoint categories. Results and discussion: The LCA results showed an increase in the retrofit and Capture scenarios compared to the no Capture scenario in the impact categories of eutrophication air, ecotoxicity water, ecotoxicity ground surface soil, eutrophication water, human health cancer ground surface soil, human health cancer water, human health noncancer ground surface soil, ozone depletion air, human health noncancer water, and ionizing radiation. The reductions were observed in the retrofit and Capture scenarios in the impact categories of acidification, human health criteria air-point source, human health noncancer air, ecotoxicity air, global warming, human health cancer air, and respiratory effects. Conclusions: Although the four LCIA methodologies significantly differ in terms of reference substances used for individual impact categories, all (TRACI, IMPACT2002+, CML2001, and EDIP 97) showed similar results in all impact categories. © 2013 Springer-Verlag Berlin Heidelberg.

power plant post combustion Carbon Dioxide Capture an opportunity for membranes
Journal of Membrane Science, 2010Co-Authors: Timothy C. Merkel, Richard W BakerAbstract:Abstract Carbon Dioxide Capture from power plant flue gas and subsequent sequestration is expected to play a key role in mitigating global climate change. Conventional amine technologies being considered for separating CO 2 from flue gas are costly, energy intensive, and if implemented, would result in large increases in the cost of producing electricity. Membranes offer potential as an energy-efficient, low-cost CO 2 Capture option. Recently, working with the U.S. Department of Energy (DOE), we have developed membranes with CO 2 permeances of greater than 1000 gpu and a CO 2 /N 2 selectivity of 50 at 30 °C. This permeance is ten times higher than commercial CO 2 membranes and the selectivity is among the highest reported for non-facilitated transport materials. These membranes, in combination with a novel process design that uses incoming combustion air as a sweep gas to generate driving force, could meet DOE CO 2 Capture cost targets. Under these conditions, improving membrane permeance is more important than increasing selectivity to further reduce the cost of CO 2 Capture from flue gas. Membrane cost and reliability issues will be key to the eventual competitiveness of this technology for flue gas treatment.
