ʻO ka decarburization kinoea kūlohelohe (decarbonization) skid, he mea nui i ka hoʻomaʻemaʻe kinoea maoli a i ʻole ka mālama ʻana.

ʻAʻole pono e ʻoi aku ma mua o 3% ka maʻiʻo o ka carbon dioxide i loko o ke kinoea kūlohelohe. A ʻo ka carbon dioxide i loko o ka wai ma hope o ke kila i kahi corrosive ikaika loa. Inā like ka PH waiwai, ʻoi aku ka kiʻekiʻe o ka ratio acidity o carbon dioxide, no laila ʻoi aku ka kiʻekiʻe o ka corrosion degere o carbon dioxide ma ke kila.

ʻO Pressure Swing Adsorption (PSA) kahi ʻenehana hou i hoʻohana ʻia e hoʻokaʻawale i ka hui kinoea i ka ʻenehana hoʻokaʻawale adsorption. Ke hoʻohālikelike ʻia me ke ʻano hoʻoheheʻe kemika maʻamau, ʻoi aku ka maikaʻi o ka ʻenehana PSA no ka wehe ʻana a me ka hoʻihoʻi ʻana o H2S a me CO2 mai ke kinoea maoli, a ke hoʻomohala ikaika ʻia nei.

ʻO kaʻenehana hoʻokaʻawale kinoea PSA nā mea maikaʻi o ka hana maʻalahi, ka haʻahaʻa haʻahaʻa haʻahaʻa, dehydration i ka wā e wehe ana i ka CO2, ka hau haʻahaʻa o ke kinoea hoʻomaʻemaʻe a me ka wai, a hiki i nā huahana ke hoʻokō i nā koi o ka hoʻokuʻu kinoea. Hiki ke hoʻohana ʻia ka PSA no ka ʻike CO2 a me ka desulfurization koho i ke kinoea maoli.

Ua lawe ʻia ka adsorption ma lalo o ke kaomi a ua lawe ʻia ka desorption ma lalo o ke kaomi hoʻemi. No ka mea pōkole ka pōʻai adsorption a ʻaʻole hiki ke hoʻopau ʻia ka wela adsorption i ka manawa, hiki ke hoʻohana ʻia no ka desorption. No laila, ʻaʻohe loli iki ka mahana o ka moena adsorption e ka wela adsorption a me ka wela desorption, hiki ke manaʻo ʻia he kaʻina isothermal. Hoʻokahi paʻa adsorption moe hana, ina paha he wela kowali adsorption a puʻe kowali adsorption, no ka mea, ka adsorbent pono e regenerated, ka adsorption mea intermittent. Ma ka ʻoihana, hoʻohana ʻia ʻelua mau moena adsorption a ʻoi aku paha, no laila e hoʻokō ʻia ka adsorption a me ka hoʻoponopono hou ʻana o ka moena adsorption (a i ʻole ka huli ʻana), e hōʻoia i ka hoʻomau o ke kaʻina hana adsorption holoʻokoʻa.

Nā hiʻohiʻona hana

He 90% hiki ke hoʻokaʻawale ʻia ka CO2 e ka hoʻololi kaomi a me ka adsorption kino, me ka ʻole o ka hopena kemika. Ma waho aʻe o ka wehe ʻana o CO2, hoʻohana nui ʻia ka ʻenehana PSA i ka hoʻihoʻi ʻana a me ka hoʻomaʻemaʻe ʻana o H2, CH4, CO, CO2 a me nā kinoea ʻē aʻe.
