Patent number: 8329458Abstract: A triphasic bioreactor for physico-chemically treating a gas is disclosed. The triphasic bioreactor comprises a reaction chamber with a liquid and biocatalysts in suspension in the liquid, for catalyzing a reaction between the gas and the liquid to obtain a treated gas and a solution containing a reaction product. A gas bubbling means is provided in the reaction chamber for bubbling the gas to be treated into the liquid thereby dissolving the gas into the liquid and increasing a pressure inside the reaction chamber. The bioreactor further comprises a liquid inlet in fluid communication with the reaction chamber for receiving the liquid and filling the reaction chamber, a liquid outlet in fluid communication with the reaction chamber for releasing the solution and a gas outlet in fluid communication with the reaction chamber to release the treated gas. The bioreactor further comprises a retention device to retain the biocatalysts in the reaction chamber.Type: GrantFiled: June 4, 2010Date of Patent: December 11, 2012Assignee: CO2 Solutions Inc.Inventors: Carmen Parent, Frédéric Dutil

Patent number: 8277769Abstract: A process is disclosed for recycling carbon dioxide emissions from a fossil-fuel power plant into useful carbonated species The process primarily comprises the steps of: a) burning the fossil fuel, thereby generating heat and a hot exhaust gas containing CO2; and b) converting the heat into energy. The process is characterized in that it further comprises the steps of: c) cooling the exhaust gas; and d) biologically transforming the CO2 contained in the cooled exhaust gas into carbonated species, thereby obtaining a low CO2 exhaust gas and producing useful carbonated species. The low CO2 exhaust gas obtained in step d) can be released in the atmosphere without increasing the problem of greenhouse effect.Type: GrantFiled: October 14, 2011Date of Patent: October 2, 2012Assignee: CO2 Solutions Inc.Inventors: Sylvie Fradette, Jean Ruel

Publication number: 20120129236Abstract: A formulation and a process for CO2 capture, where a CO2-containing gas in contacted with water, biocatalyst and an amino acid compound, enabling the dissolution and transformation of the CO2 into bicarbonate ions and hydrogen ions, producing an ion-rich solution and a CO2-depleted gas. The amino acids may present slow absorption kinetics and having elevated stability such that absorption is enhanced in combination with the biocatalyst. The amino acid compound and the biocatalyst may be selected such that the active sites of the biocatalyst benefit from proton removal facilitated by the amino acid compounds, thus improving the CO2 absorption.Type: ApplicationFiled: August 4, 2010Publication date: May 24, 2012Applicant: CO2 SOLUTIONS INC.Inventors: Sylvie Fradette, Julie Gingras, Jonathan Carley, Glenn R.

Publication number: 20120129246Abstract: A formulation and process for capturing CO2 use an absorption mixture containing water, biocatalysts and a carbonate compound. The process includes contacting a CO2-containing gas with the absorption mixture to enable dissolution and transformation of CO2 into bicarbonate and hydrogen ions, thereby producing a CO2-depleted gas and an ion-rich solution, followed by subjecting the ion-rich solution to desorption. The biocatalyst improves absorption of the mixture comprising carbonate compounds and the carbonate compound promotes release of the bicarbonate ions from the ion-rich solution during desorption, producing a CO2 gas stream and an ion-depleted solution.Type: ApplicationFiled: August 4, 2010Publication date: May 24, 2012Applicant: CO2 SOLUTIONS INC.Inventors: Sylvie Fradette, Julie Gingras, Jonathan Carley, Glenn R.
