Ukusetyenziswa kwenkqubo yokucoca i-molecular sieve kwiyunithi yokwahlula umoya

Umoya oxinaniswe yi-compressor yomoya usebenzisa i-adsorbent esebenzayo ye-alumina kunye ne-molecular sieve yokususa amanzi, i-carbon dioxide, i-acetylene, njl. Njenge-adsorbent, i-molecular sieve ingabhengeza ezinye iigesi ezininzi, kwaye inotyekelo olucacileyo kwinkqubo ye-adsorption. Ubukhulu bepolarity yeemolekyuli ezinobungakanani obufanayo, kokukhona zibhengezwa ngokulula sisisefu semolekyuli, kwaye ngokukhona zinkulu iialekyuli ezingaxutywanga, kokukhona zibhengezwa ngokulula sisisefo semolekyuli. I-adsorbs ikakhulu i-H2O, i-CO2, i-C2, i-H2 kunye nezinye izinto ezingcolileyo ze-CnHm emoyeni; Ukongeza kumthamo we-adsorption ye-molecular sieve ehambelana nohlobo lwezinto ezithengiswayo, kodwa inxulumene nokuxinana kwezinto ezibhengezwayo, kunye nobushushu, umoya ocinezelekileyo ngaphambi kokungena kwinkqubo yokucoca kodwa nakwinqaba yokupholisa umoya ukunciphisa ubushushu be-adsorbed. umoya ngaphambi kokungena kwinkqubo yokucoca, kunye nomxholo wamanzi emoyeni unxulumene nobushushu, iqondo eliphantsi lobushushu lisezantsi umthamo wamanzi. Ngoko ke, inkqubo yokucoca kuqala idlula kwinqaba yokupholisa umoya ukunciphisa ubushushu bomoya, ngaloo ndlela inciphisa umxholo wamanzi emoyeni.
Igesi ecinezelweyo evela kwinqaba yokupholisa umoya ifakwe kwinkqubo yokucoca, eyona nto iqulunqwe zi-adsorbers ezimbini, i-heater yomphunga kunye ne-liquid-gas separator. I-adsorber ye-molecular sieve yi-horizontal bunk bed structure, umaleko ongezantsi ulayishwe nge-alumina esebenzayo, umaleko ongaphezulu ulayishwe ngesihluzo se-molekyuli, kunye nomsebenzi wokutshintsha izibhengezo ezimbini. Xa enye i-adsorber isebenza, enye i-adsorber iyahlaziywa kwaye ivuthelwe ngokubanda ukuze isetyenziswe. Umoya oxinyiweyo ovela kwinqaba yokupholisa umoya ususwe ngumbhengezo wamanzi, i-CO2 kunye nezinye izinto ezingcolileyo ezifana ne-CnHm. Ukuhlaziywa kwe-sefo ye-molecular yenziwe ngamanqanaba amabini, enye yi-nitrogen engcolileyo evela kwi-fractionator yomoya, ifudunyezwa yi-heater yomphunga ukuya kwiqondo lokushisa ngokutsha, faka i-adsorber ekuvuseleleni ubushushu, uhlalutye amanzi adsorbed kunye ne-CO2, ebizwa ngokuba yinqanaba lokufudumeza. enye initrogen emdaka hayi ngesifudumezi somphunga, vuthela ubushushu obuphezulu be-adsorber ukuya kwiqondo lobushushu begumbi, iya kucazulula amanzi adsorbed kunye ne-CO2 ngaphandle kwe-adsorber. Kubizwa ngokuba sisigaba sokuvuthela okubandayo. Inkunkuma yenitrogen esetyenziselwa ukufudumeza kunye nokuvuthela ngokubanda ikhutshelwa emoyeni ngesithulisi sokuvuthela.
