Ukusetshenziswa kwesistimu yokuhlanza i-molecular sieve kuyunithi yokuhlukanisa umoya

Umoya ocindezelwe yi-compressor yomoya usebenzisa i-alumina ecushiwe ye-adsorbent kanye nesisefo samangqamuzana ukususa amanzi, i-carbon dioxide, i-acetylene, njll. Njenge-adsorbent, isisefo samangqamuzana singakhanga amanye amagesi amaningi, futhi sinokuthambekela okusobala enqubweni yokukhangisa.Lapho i-polarity yama-molecule anobukhulu obufanayo iba nkulu, kukhangiswa kalula ngesisefo samangqamuzana, futhi iba mkhulu ama-athomu angagcwele, kukhangeka kalula ngesisefo samangqamuzana.Ikhangisa kakhulu i-H2O, CO2, C2, H2 nokunye ukungcola kwe-CnHm emoyeni;Ngaphezu komthamo we-adsorption wesisefo samangqamuzana ahlobene nohlobo lwezinto ezikhangisiwe, kodwa futhi ahlobene nokuhlangana kwezinto ezikhangisiwe, kanye nezinga lokushisa, umoya ocindezelwe kangako ngaphambi kokungena ohlelweni lokuhlanza kodwa futhi nangombhoshongo wokupholisa umoya ukuze unciphise izinga lokushisa. umoya ngaphambi kokungena ohlelweni lokuhlanza, futhi okuqukethwe kwamanzi emoyeni kuhlobene nezinga lokushisa, izinga lokushisa eliphansi liba phansi okuqukethwe kwamanzi.Ngakho-ke, uhlelo lokuhlanza luqala ludlule embhoshongweni wokupholisa umoya ukuze lunciphise izinga lokushisa lomoya, ngaleyo ndlela lunciphise okuqukethwe kwamanzi emoyeni.
Igesi elicindezelwe elisuka embhoshongweni wokupholisa umoya lifakwa ohlelweni lokuhlanza, olwakhiwe ikakhulukazi ama-adsorbers amabili, i-heater yesitimu kanye nesihlukanisi segesi ewuketshezi.I-adsorber ye-molecular sieve iyisakhiwo sombhede ovundlile, ungqimba olungezansi lulayishwe i-alumina ecushiwe, ungqimba olungaphezulu lulayishwe ngesisefo samangqamuzana, kanye nomsebenzi wokushintsha izikhangisi ezimbili.Uma i-adsorber eyodwa isebenza, enye i-adsorber ikhiqizwa kabusha futhi ishaywa umoya ukuze isetshenziswe.Umoya ocindezelwe ovela embhoshongweni wokupholisa umoya ususwa i-adsorber yamanzi, i-CO2 nokunye ukungcola okufana ne-CnHm.Ukuvuselelwa kwe-sieve yama-molecular kwenziwa ngezigaba ezimbili, esinye i-nitrogen engcolile evela ku-fractionator yomoya, eshisiswe yi-heater yesitimu ukuya ekushiseni kabusha, faka i-adsorber ekuvuseleleni ukushisa, ukukhipha amanzi adsorbed kanye ne-CO2, ebizwa ngokuthi isiteji sokushisa, enye i-nitrogen engcolile hhayi nge-heater yesitimu, vuthela i-adsorber ephezulu yezinga lokushisa kuya ekamelweni lokushisa, izokhipha amanzi adsorbed kanye ne-CO2 ngaphandle kwe-adsorber.Kubizwa ngesigaba sokushaywa okubandayo.I-nitrogen eyimfucumfucu esetshenziselwa ukufudumeza nokuphephetha okubandayo ikhishelwa emkhathini ngesithulisi esishisayo.
