摘要： The present invention is based on the realization that the carbon dioxide component of industrial gas streams also containing steam can be processed so to utilize either as latent and/or sensible heat the heat available from the steam component to assist in separating carbon dioxide from the remainder of the gas stream. For example, flue gases produced by power stations burning brown coal, black coal or natural gas inherently contain a useful amount of energy that can be harnessed according to the present invention. According to particular preferred forms of the invention, nitrogen and sulphur constituent such as SOx and NOx, H2S and other nitrogen containing compounds may also be removed from the gas stream through direct contact with the absorbing medium and used to produce by-products such as fertilizer material.

摘要： The present invention relates to reactor vessels such as absorbing or stripping columns that are suitable for capturing carbon dioxide from flue gas streams of fossil fuel fired powered stations such as coal fired power stations generating 100 to 500 MW. The side walls of the reactors are made of concrete or structural ceramics that are preferrably steel reinforced. The reactors are on a sufficiently large scale such that a flue gas stream in the order of at least 1,000 t/hr and normally greater than 2,000 or 3,000 t/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 standing structures or, alternatively, the absorbing column may be located at least partially within the stripping column.

摘要： The present invention relates to a process and plant for removing acid gases such as carbon dioxide, sulphur containing compounds and nitrogen containing compounds from gas streams including high and low pressure gas streams. A solvent solution containing alkali carbonates absorbs the acid gases including carbon dioxide and either one or both of sulphur and/or nitrogen containing compounds. The bicarbonate is regenerated into a carbonate form to provide a gas stream rich in carbon dioxide, and sulphur and/or nitrogen containing compounds are recovered.

摘要： A membrane is used for separating carbon dioxide from a gas phase. The membrane includes a substrate having micro-pores that extend through the substrate and a thin hydrophobic coating on one side of the substrate in which the pores of the substrate are substantially unobstructed by the coating so that the gas phase can penetrate the pores. The coating opposes or substantially resists a liquid solvent for absorbing carbon dioxide from penetrating the pores of the membrane from the side having the coating. The membrane may also be used for separating carbon dioxide in a flue gas of a coal fired power station. Further, the coating may be relatively inert to the liquid solvent compared to the substrate.

摘要： The present invention relates to gas separation membranes for separating carbon dioxide from other gas species, polymer compositions suitable for this application, and processes for the manufacture thereof. In particular, the present invention relates polymeric compositions comprising a host polymer that is permeable to the targeted gas species, such as carbon dioxide and has a selectivity for the target gas species over other gas species. The polymeric composition also comprises domains of a polymeric material that are, for example at least 0.5 nm in diameter and that have a higher permeability for the targeted gas compared to the host polymer. The present invention can provide membranes that have a permeability and selectivity above the Robeson's upper bound.
