Ukusetyenziswa kwenkqubo yokucoca isihluzo se-molecular kwiyunithi yokwahlula umoya

Umoya ocinezelwe yi-air compressor usebenzisa i-alumina ethile esebenzayo kunye ne-molecular seeve ukususa amanzi, i-carbon dioxide, i-acetylene, njl. Njenge-adsorbent, i-molecular seeve inokufunxa ezinye iigesi ezininzi, kwaye inomdla ocacileyo kwinkqubo ye-adsorption. Okukhona i-polarity yee-molecules ezinobukhulu obufanayo inkulu, kokukhona kulula ukufunxa nge-molecular seeve, kwaye okukhona ii-molecules ezingagcwaliyo zikhulu, kokukhona kulula ukufunxa nge-molecular seeve. Ifunxa kakhulu i-H2O, i-CO2, i-C2, i-H2 kunye nezinye izinto ezingcolileyo ze-CnHm emoyeni; Ukongeza kumthamo we-adsorption we-molecular seeve onxulumene nohlobo lwezinto ezifunxayo, kodwa unxulumene noxinzelelo lwezinto ezifunxayo, kunye nobushushu, ngoko umoya ocinezelweyo ngaphambi kokungena kwinkqubo yokucoca kodwa nangokusebenzisa i-air cooling tower ukunciphisa ubushushu bomoya ngaphambi kokungena kwinkqubo yokucoca, kwaye umxholo wamanzi emoyeni unxulumene nobushushu, kokukhona ubushushu buphantsi, kokukhona umxholo wamanzi uphantsi. Ngoko ke, inkqubo yokucoca idlula kuqala kwinqaba yokupholisa umoya ukuze inciphise ubushushu bomoya, ngaloo ndlela inciphise umthamo wamanzi emoyeni.
Igesi ecinezelweyo evela kwinqaba yokupholisa umoya ifakwa kwinkqubo yokucoca, equlathe ikakhulu ii-adsorbers ezimbini, i-heater yomphunga kunye ne-liquid-gas separator. I-molecular sieve adsorber sisakhiwo sebhedi esithe tyaba, umaleko ongezantsi ugcwele i-alumina esebenzayo, umaleko ongaphezulu ugcwele i-molecular sieve, kwaye ii-adsorbers ezimbini ziyatshintshana. Xa enye i-adsorber isebenza, enye i-adsorber iyavuselelwa kwaye ivuthelwe ngokubandayo ukuze isetyenziswe. Umoya ocinezelweyo ovela kwinqaba yokupholisa umoya ususwa yi-adsorber yamanzi, i-CO2 kunye nezinye izinto ezingcolileyo ezifana ne-CnHm. Ukuvuselelwa kwesihluzo se-molecular kwenziwa ngamanqanaba amabini, elinye yi-nitrogen engcolileyo evela kwi-air fractionator, efudunyezwa yi-steam heater ukuya kubushushu bokuvuselela, ingena kwi-adsorber ukuze ivuselele ubushushu, ihlalutye amanzi afakwe i-adsorber kunye ne-CO2, ebizwa ngokuba yinqanaba lokufudumeza, elinye yi-nitrogen engcolileyo engadluli kwi-steam heater, ivuthele i-adsorber yobushushu obuphezulu ukuya kubushushu begumbi, iya kwahlula amanzi afakwe i-adsorber kunye ne-CO2 kwi-adsorber. Ibizwa ngokuba yi-cold blow phase. I-nitrogen emdaka esetyenziselwa ukufudumeza nokuvuthela ngokubandayo ikhutshwa emoyeni ngesixhobo sokuthula umoya.
