摘要:
A novel stack application for improved carbon dioxide and particle removal/collection from flue gases produced during coal power-generation processes. Flue gas tangential inlet velocity is increased to subject upward-flowing flue gas in a stack to a centrifugal force, thereby propelling entrained solid particles and CO2 in the flue gas to the stack wall for collection. Collection efficiency is further improved by a cascading water film or algae-laden water film on the inside of the stack wall and on surfaces of an optional internally mounted vortex generator to eliminate the re-entrainment of small particles and for ease of transporting the captured particles in a slurry. The stack can also be utilized as a photochemical or a biological reactor to promote a photosynthesis reaction between carbon dioxide and algae-laden water to form carbohydrate substrates for carbon dioxide sequestration and utilization.
