Patent ID: 8076122

Claim:
An integrated process comprising the steps of: a) converting at least one hydrocarbonaceous asset to produce a CO 2 -containing gas; b) absorbing at least a portion of the CO 2 of the CO 2 -containing gas into an absorption liquid in an absorption tower, wherein the absorption liquid flows downward, and wherein the CO 2 -containing gas flows upward; c) collecting at least a portion of the CO 2 -containing absorption liquid obtained in step (b) and, in a photobiofuels process, providing said collected CO 2 -containing absorption liquid to support photosynthesis; d) forming an algal and/or diatomaceous biomass in the collected CO 2 -containing absorption liquid; e) removing the formed biomass from the absorption liquid, thereby forming a regenerated absorption liquid; f) recycling at least a portion of the regenerated absorption liquid to the absorption tower; g) producing O 2 in the photobiofuels process; and h) providing at least a portion of said O 2 as (i) a gaseous oxidant for producing synthesis gas, (ii) an oxidant of synthesis gas for producing power therefrom, or (iii) combinations thereof; wherein the photobiofuels process is a closed photobiofuels process.
