Class & Home Problems: Carbon Dioxide Capture From Coal-Fired Power Plants Using Calcium Looping
Calcium looping is based on the simple premise of the reversible reaction between CO2 and CaO. This reaction can be used for separation of CO2 from a mixture of gases; most notably the technology finds applications in CO2 removal from gas streams in fossil fuel-based energy systems. This article gives a brief overview of the calcium looping process and uses the example of a coal-fired power plant for discussing several aspects, including material balances and energy requirements. This article, which is based on an important topic of current research, is written in a format that can be directly adopted for a project in introductory chemical engineering courses.
