Publication number: 20130280757Abstract: The present disclosure provides an algae bioreactor and process. The algae bioreactor includes a container with an inlet and an outlet. An algae suspension present in the container interior moves from an inlet to an outlet along a flowpath. A light assembly, a liftwall, and a gas conduit are located in the container interior. The gas conduit extends along a length of the container and emits gas bubbles into the algae suspension. A diffuser is located on a bottom wall of the container, The flowpath, the liftwall, the gas conduit, and the diffuser produce an active flow of the algae from the container inlet to the container outlet. The container may be a deep-vessel container.Type: ApplicationFiled: December 15, 2011Publication date: October 24, 2013Inventors: Stephen W. Dvorak, Douglas Van Ornum

Patent number: 8563296Abstract: Embodiments of a process for discharging amine byproducts formed in an amine-based solvent are provided. The process comprises the steps of contacting the amine-based solvent with flue gas comprising carbon dioxide, oxygen, nitrogen, NOx, SOx, or mixtures thereof to form a carbon dioxide-laden amine-based solvent that contains the amine byproducts. Carbon dioxide is separated from the carbon dioxide-laden amine-based solvent to form a carbon dioxide-depleted amine-based solvent. The amine byproducts from the carbon dioxide-depleted amine-based solvent are fed to an algae source.Type: GrantFiled: November 24, 2010Date of Patent: October 22, 2013Assignee: UOP LLCInventors: David W. Greer, Graham Ellis, Edward Zbacnik, Lubo Zhou
