Patent number: 10850231Abstract: Techniques are described for chemical sequestration of carbon dioxide and production of precipitated magnesium carbonate. The process can include contacting carbon dioxide from industrial emissions with water and magnesium-containing particulate material, such as serpentinite, which is thermally pre-treated and has a particle size of at most 75 microns. The process can also include separation of the loaded aqueous stream from the solids, followed by precipitation of magnesium carbonate material that includes carbon and oxygen from industrial emissions and magnesium from serpentinite or chrysotile mining residue, for example.Type: GrantFiled: November 2, 2018Date of Patent: December 1, 2020Assignee: Institut National de la Recherche ScientifiqueInventors: Guy Mercier, Jean-Francois Blais, Emmanuelle Cecchi, Sanoopkumar Puthiya Veetil, Louis-Cesar Pasquier, Sandra Kentish

Patent number: 9440189Abstract: Processes, methods, system and uses in relation to chemical sequestration of carbon dioxide from a carbon dioxide containing gas by carbonation of an alkaline earth metal containing material. The carbon dioxide containing gas is contacted with an aqueous slurry in a carbonation unit for carbonation of at least a portion of the alkaline earth metal to produce a carbon dioxide depleted gas and a carbonate loaded slurry which is substantially exempt of precipitated alkaline earth. metal carbonates. The carbonate loaded slurry is then separated into an aqueous phase and a solid phase; and the aqueous phase is supplied to a precipitation unit for precipitating alkaline earth metal carbonates. The carbonation stage may be performed at a carbonation temperature between about 10° C. and about 40° C. and a carbonation pressure between about 1 bar and about 20 bars. The solid phase may be recycled to the carbonation stage.Type: GrantFiled: March 7, 2013Date of Patent: September 13, 2016Assignee: INSTITUT NATIONAL DE LA RECHERCHE SCIENTIFIQUE (INRS)Inventors: Guy Mercier, Jean-Francois Blais, Emmanuelle Cecchi, Sanoopkumar Puthiya Veetil, Louis-Cesar Pasquier, Sandra Kentish

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

Publication number: 20100313758Abstract: 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.Type: ApplicationFiled: June 12, 2009Publication date: December 16, 2010Applicant: CO2CRC TECHNOLOGIES PTY LTD.Inventors: Geoff Stevens, Jilska Perera, Julianna Franco, Sandra Kentish
