TECHNOLOGIES FOR CAPTURE OF CARBON DIOXIDE

摘要

This paper reviews the technologies that could be used to capture CO_2 from use of fossil fuels. It identifies the main opportunities for capturing CO_2 which are power generation, other large energy consuming industries and production of carbon-free energy carriers. The three main overall methods of capturing CO_2 in power plants: post-combustion capture, oxyfuel combustion and pre-combustion capture are described. The paper also describes the various CO_2 separation techniques that could be used and their current development status. The impacts of different CO_2 capture technologies on the thermal efficiencies and costs of power plants are summarized, based on recent studies carried out by process technology developers and plant engineering contractors.
