Publication number: 20230405517Abstract: An embodiment of the present invention relates to an aqueous solvent solution for absorbing carbon dioxide, and a process using an aqueous solvent solution for absorbing carbon dioxide. The aqueous solvent solution having a catalytic compound dissolved in the water that is an alkali salt of an N-substituted amino acid and at least one base that is dissolved in water. The catalytic compound assisting in forming a bicarbonate.Type: ApplicationFiled: September 16, 2021Publication date: December 21, 2023Inventors: Barry Hooper, Geoffrey Stevens, Craig Osborne

Patent number: 10843124Abstract: The present invention relates to a process and contactor vessel in which gas and liquid contact occurs to facilitate mass transfer therebetween. In one embodiment, the process includes a fluidised bed including mobile inert primary objects and secondary particles that facilitate turbulent mixing and enhanced gas/liquid surface area in the contactor.Type: GrantFiled: November 16, 2016Date of Patent: November 24, 2020Assignee: REDEEM CCS PTY LTDInventor: Barry Hooper

Patent number: 9757682Abstract: 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.Type: GrantFiled: April 21, 2011Date of Patent: September 12, 2017Assignee: UNO TECHNOLOGY PTY LTDInventors: Kohei Endo, Geoffrey Stevens, Barry Hooper, Sandra Elizabeth Kentish, Clare Anderson

Patent number: 8641805Abstract: 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.Type: GrantFiled: May 12, 2008Date of Patent: February 4, 2014Assignee: CO2CRC Technologies PTY Ltd.Inventors: Geoff Stevens, Barry Hooper, Craig Dugan, Paul Anthony Webley

Patent number: 8388919Abstract: 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.Type: GrantFiled: April 19, 2011Date of Patent: March 5, 2013Assignee: CO2CRC Technologies Pty LtdInventors: Barry Hooper, Geoff Stevens, Sandra Kentish
