Amine-impregnated Alumina Solid Sorbent for CO2 Capture

DESCRIPTION
The project covers the sorbent preparation and experimental testing from laboratory to pilot plant scale, with the aims of developing the material production process; demonstrating the technology in the pilot plant scale; assessing the capture process performances and costs; and defining the requirements for the scale-up to commercial power plants in terms of plant design and operation, and energy integration.
OBJECTIVES
The ASC2 project has a holistic approach from the laboratory solid sorbent development to the preparation of sorbent for pilot plant operation, pilot plant testing and also includes the scale-up of the concept to commercial coal power plants for both existing and new applications. The main objective of the project is the development and demonstration of new and innovative solid sorbents. New porous materials will be developed in order to obtain the best performances for amine deposition on solid support and for CO2 absorption/desorption cycle. The most effective solution, selected by screening in laboratory tests, will be produced in a suitable quantity (about a ton) and will be tested in a pilot installation fed with the flue gases from a commercial coal-fired power plant.
Specific objectives are:
- Development of new sorbents with high CO2 loading (up to 50 mg/g sorbent), low regeneration energy requirement (2.5 kJ/kgCO2) and fast reaction kinetics
- Development of new sorbents which avoid the use of water
- Reduction or avoidance of thermal and oxidative degradation of sorbents
- Research about the impact of flue gas contaminants (particulates, sulphur- and nitrous oxides) on the capture process with real flue gases
- Optimization of heat integration methods to limit impact on the power production process. Conceptual studies, including power plant integration through process and equipment modelling to improve 3-4 efficiency points in capture systems
CIRCE'S ROLE
Also, CIRCE will head the dissemination and exploitation of the results achieved in ASC2 project. It will ensure the highest impact of the project, as well as the development of an appropriate structure to guarantee the continuity of the project once it is over.
