CAPTURE OF CARBON DIOXIDE FROM FLUE GASES IN LARGE-SCALE ALGAE CULTIVATION

摘要

A unit for the selective absorption into water of carbon dioxide from large volumes of flue gases or the direct absorption into water of large volumes of more or less pure gaseous carbon dioxide; said unit comprising one or more casings within which a large plurality of spray heads generate ultra-thin, fan-shaped sprays of water which are efficient absorbers of carbon dioxide; said carbon dioxide or flue gases being delivered to said casings via suitable trunks; said spray heads being supplied with pressurised water via suitable conduits; carbonated water draining away through suitable drainage lines, decompression wells and buffering units; said flue gases, stripped of carbon dioxide, discharging to exhaust stacks via pressure relief valves which maintain optimal carbonation pressure within said casings and optional water capture units; said carbon dioxide, flue gases and sorbent water being cooled to a suitable temperature for carbonation.
