Study Notes
Power Plant Cost Performance and Carbon Capture Summary
- The text contains information about modern power plant cost performance indicators and case studies for carbon capture.
- The link provided leads to additional resources for further reading.
- The text discusses the process of carbon capture during power generation, including post-combustion capture and pre-combustion fuel gasification.
- It describes the different methods of carbon capture, such as absorption and chemical absorption systems.
- The preferred option for carbon capture at low CO2 concentrations is chemical absorption systems, which have been in use since the 1980s.
- The chemical absorption process involves the reaction of CO2 with HOC2H4NH2 to produce HOC2H4NHCOO- and HOC2H4NH3+.
- The rate of reaction in the absorption process is largely determined by a combination of chemical reactions.
- The design for carbon capture is based on fast reaction within a thin layer close to the liquid surface due to the very high rate constant.
- The local overall balance in the bulk liquid phase is modified to account for the reaction of A and B.
