Kwintsimi yokwahlulwa kwegesi kunye nokucocwa, ngokuqiniswa kokhuseleko lokusingqongileyo, kunye nemfuno yangoku yokungathathi hlangothi kwekhabhoni, i-CO.2ukubamba, ukufunxwa kweegesi eziyingozi, kunye nokunciphisa ukukhutshwa kwezinto ezingcolileyo kuye kwaba yimibandela ebaluleke ngakumbi nangakumbi. Kwangaxeshanye, kunye notshintsho kunye nokuphuculwa kweshishini lethu lokuvelisa, imfuno yegesi yococeko ephezulu iyanda. Ukwahlula igesi kunye nobuchwephesha bokucoca kubandakanya i-distillation yobushushu obuphantsi, i-adsorption kunye nokusasazwa. Siza kwazisa iinkqubo ezimbini eziqhelekileyo kunye ezifanayo ze-adsorption, ezizezi, i-press swing adsorption (PSA) kunye ne-avaluable temperature adsorption (TSA).
I-Pressure swing adsorption (PSA) umgaqo ongundoqo usekwe kumahluko kwiimpawu ze-adsorption zamacandelo egesi kwizinto eziqinileyo kunye neempawu zokutshintsha umthamo we-adsorption ngoxinzelelo, usebenzisa inguqu yoxinzelelo lwamaxesha athile ukugqiba ukwahlukana kunye nokucocwa kwegesi. I-variable-temperature adsorption (TSA) ikwathatha ithuba lokwahluka ekusebenzeni kwe-adsorption yamacandelo egesi kwizinto eziqinileyo, kodwa umahluko kukuba umthamo we-adsorption uya kuchatshazelwa lutshintsho lobushushu, kunye nokusetyenziswa kwe-periodical variable-ubushushu ukuphumeza ukwahlulwa kwegesi. kunye nokuhlanjululwa.
I-adsorption ye-pressure swing isetyenziswa ngokubanzi kwi-carbon capture, i-hydrogen kunye nemveliso ye-oksijini, ukuhlukana kwe-nitrogen methyl, ukuhlukana komoya, ukususwa kwe-NOx kunye nezinye iindawo. Ngenxa yokuba uxinzelelo lunokutshintshwa ngokukhawuleza, umjikelo woxinzelelo lwe-swing adsorption ngokuqhelekileyo umfutshane, onokugqiba umjikelo kwimizuzu embalwa. Kwaye i-adsorption yokushisa eguquguqukayo isetyenziswa ikakhulu ekubanjweni kwekhabhoni, ukuhlanjululwa kwe-VOCs, ukomiswa kwegesi kunye namanye amasimi, kuthintelwe izinga lokutshintshwa kobushushu benkqubo, ukufudumeza kunye nexesha lokupholisa lide, umjikelo we-adsorption wokushisa oguqukayo uya kuba mde kakhulu, ngamanye amaxesha unokufikelela ngakumbi. ngaphezu kweeyure ezilishumi, ngoko indlela yokufezekisa ukufudumeza ngokukhawuleza kunye nokupholisa ikwayenye yeendlela zophando lwe-adsorption yobushushu obuguquguqukayo. Ngenxa yomahluko kwixesha lomjikelo wokusebenza, ukwenzela ukuba isetyenziswe kwiinkqubo eziqhubekayo, i-PSA isoloko ifuna iinqaba ezininzi ngokufana, kwaye iinqaba ezi-4-8 ziinombolo eziqhelekileyo ezihambelanayo (okufutshane umjikelo wokusebenza, amanani afanayo ngakumbi). Njengoko ixesha le-adsorption yobushushu obuguquguqukayo lilide, iikholamu ezimbini zihlala zisetyenziselwa ukunyuswa kobushushu obuguquguqukayo.
Ezona zibhengezo ziqhele ukusetyenziswa kwi-adsorption yobushushu obuguquguqukayo kunye noxinzelelo lwe-adsorption swing yi-molecular sieve, i-activated carbon, i-silica gel, i-alumina, njl. inkqubo yokwahlula. Uxinzelelo lwe-adsorption kunye noxinzelelo lwe-atmospheric desorption ziimpawu zoxinzelelo lwe-swing adsorption. Uxinzelelo lwe-adsorption ye-pressurization inokufikelela kwiiMPa ezininzi. Ubushushu obusebenzayo be-adsorption yobushushu obuguquguqukayo buhlala bukufutshane nobushushu begumbi, kwaye iqondo lobushushu bobushushu bobushushu linokufikelela ngaphezulu kwe-150 ℃.
Ukuze kuphuculwe ukusebenza kakuhle kunye nokunciphisa ukusetyenziswa kwamandla, i-vacuum pressure swing adsorption (VPSA) kunye nobuchwepheshe be-vacuum swing adsorption (TVSA) buphuma kwi-PSA kunye ne-PSA. Le nkqubo intsonkothe ngakumbi kwaye iyabiza, iyenza ilungele ukusetyenzwa kwerhasi enkulu. I-vacuum swing adsorption yi-adsorption kuxinzelelo lwe-atmospheric kunye ne-desorption ngokumpompa i-vacuum. Ngokufanayo, ukucoca ngexesha lenkqubo ye-desorption kunokunciphisa ubushushu be-desorption kunye nokuphucula ukusebenza kakuhle kwe-desorption, okuya kuba luncedo ekusetyenzisweni kobushushu obuphantsi kwinkqubo yokutshintsha kweqondo lokushisa.
