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 enxulumene nohlobo lwezinto ezibhengezo, kodwa inxulumene nokuxinana kwezinto ezibhengezwayo, kunye nobushushu, umoya ocinezelekileyo ngaphambi kokungena kwinkqubo yokucoca kodwa nangenqaba yokupholisa umoya ukunciphisa ubushushu bomoya ngaphambi kokungena kwinkqubo yokucoca, kwaye umxholo wamanzi emoyeni unxulumene nobushushu obuphantsi, ubushushu obuphantsi kwamanzi. 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 yi-adsorber yamanzi, i-CO2 kunye nezinye izinto ezingcolileyo ezifana ne-CnHm. Ukuhlaziywa kwe-sefo ye-molekyuli yenziwe ngamanqanaba amabini, enye yinitrogen emdaka evela kwi-fractionator yomoya, ifudunyezwe sisifudumezi somphunga ukuya kwiqondo lokuhlaziya ngokutsha, faka i-adsorber ekuvuseleleni ubushushu, ucazulule amanzi adityanisiweyo kunye ne-CO2, ebizwa ngokuba linqanaba lokufudumeza, elinye liyinitrogen emdaka hayi ngesifudumezi-manzi somphunga, ukuvuthela ubushushu obuphezulu begumbi kunye nobushushu obuphezulu. CO2 ngaphandle kwe-adsorber. Kubizwa ngokuba sisigaba sokuvuthela okubandayo. Inkunkuma yenitrogen esetyenziselwa ukufudumeza nokuvuthela ngokubanda ikhutshelwa kwiatmosfera ngokusebenzisa isithulisi sokuvuthela.
