20130098126 | PROCESS AND PLANT FOR REMOVING ACID GASES - 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. | 04-25-2013 |
20110195005 | PLANT AND PROCESS FOR REMOVING CARBON DIOXIDE FROM GAS STREAMS - 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 SO | 08-11-2011 |
20100313758 | GAS ABSORPTION MEMBRANES AND THE MANUFACTURE THEREOF - 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. | 12-16-2010 |
20100313752 | GAS SEPARATION MEMBRANES AND PROCESSES FOR THE MANUFACTURE THEREOF - 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. | 12-16-2010 |
