Abstract

Przedmiotem wynalazku jest sposób i układ pozyskania CO<sub>2</sub> z wody morskiej za pomocą węglanowego elektrolizera, który polega na tym, że do elektrolizera węglanowego (I) jednocześnie wprowadza się pierwszym strumieniem (1) wodę morską w stanie nadkrytycznym oraz drugim strumieniem (2) CO<sub>2</sub> w stanie nadkrytycznym, następnie pod wpływem dostarczonej energii elektrycznej jony węglanowe (CO3=) powstałe z połączenia CO<sub>2</sub> z jednym atomem tlenu odbieranym od wody, transportowane są z pierwszego strumienia (1) do drugiego strumienia (2), po czym woda morska z wodorem kierowane są trzecim strumieniem (3) do skraplacza (II), gdzie woda morska jest skraplana i piątym strumieniem (5) z mniejszą ilością CO<sub>2</sub> kierowana jest na zewnątrz skraplacza (II), natomiast wodór w stanie gazowym w ósmym strumieniu (8) wraz z mieszaniną gazów wytworzoną w elektrolizerze węglanowym (I) zawierającą CO<sub>2</sub> z tlenem czwartym strumieniu (4) kieruje się do komory spalania (III), w której tlen z czwartego strumienia (4) z elektrolizera węglanowego (I) reaguje z wodorem z ósmego strumienia (8) tworząc CO<sub>2</sub>, który szóstym strumieniem wylotowym (6) kieruje się na zewnątrz komory spalania (III), zaś część CO<sub>2</sub> z parą wodną w stanie ciekłym strumieniem (7) jest sprężana za pomocą sprężarki (IV) i kierowana do elektrolizera węglanowego (I) tworząc drugi strumień (2) CO<sub>2</sub> w stanie nadkrytycznym. Dodatkowo przedmiotem zgłoszenia jest układ pozyskania CO<sub>2</sub> z wody morskiej za pomocą węglanowego elektrolizera (I).The subject of the invention is a method and system for obtaining CO<sub>2</sub> from seawater using a carbonate electrolyzer, which consists in simultaneously introducing into the carbonate electrolyzer (I) a first stream (1) of seawater in a supercritical state and a second stream (2) of CO<sub>2</sub> in a supercritical state, then under the influence of the supplied electrical energy, carbonate ions (CO3=) formed from the combination of CO<sub>2</sub> with one oxygen atom taken from water are transported from the first stream (1) to the second stream (2), after which the seawater with hydrogen are directed through the third stream (3) to the condenser (II), where the seawater is condensed and through the fifth stream (5) with a smaller amount of CO<sub>2</sub> is directed outside the condenser (II), while hydrogen in a gaseous state in the eighth stream (8) together with the gas mixture produced in the carbonate electrolyzer (I) containing CO<sub>2</sub> with oxygen in the fourth stream (4) is directed to the combustion chamber (III), in which oxygen from the fourth stream (4) from the carbonate electrolyzer (I) reacts with hydrogen from the eighth stream (8) to form CO<sub>2</sub>, which is directed outside the combustion chamber (III) in the sixth outlet stream (6), while part of the CO<sub>2</sub> with steam in the liquid state in the stream (7) is compressed by means of a compressor (IV) and directed to the carbonate electrolyzer (I) to form the second stream (2) of CO<sub>2</sub> in a supercritical state. Additionally, the subject of the application is a system for obtaining CO<sub>2</sub> from seawater using a carbonate electrolyzer (I).
