A REACTOR, PLANT AND PROCESS

摘要

The present invention relates to reactor vessels such as absorbing or str ipping columns that are suitable for capturing carbon dioxide from flue gas streams of fossil fuel fired powered stations such as coal fired power stati ons generating 100 to 500MW. The side walls of the reactors are made of conc rete or structural ceramics that are preferrably steel reinforced. The react ors are on a sufficiently large scale such that a flue gas stream in the ord er of at least 1,000t/hr and normally greater than 2,000 or 3,000t/hr can be scrubbed of carbon dioxide in a single absorption column and then recovered in a stripping column. The absorbing and stripping columns may be free stan ding structures or, alternatively, the absorbing column may be located at le ast partially within the stripping column.
