Ikhwalithi Ephakeme Abakhiqizi Begesi Yezibaseli ZaseChina - I-skid ye-Molecular sieve dehydration - Rongteng

Incazelo

I-Molecular sieve dehydration skid iyisisetshenziswa esibalulekile ekuhlanzeni igesi yemvelo noma ekulungiseni igesi yemvelo. Isisefo samangqamuzana i-alkali metal aluminosilicate crystal enesakhiwo sohlaka kanye nesakhiwo esifanayo se-microporous. Lapho igesi yokuphakelayo equkethe amanzi okulandela umkhondo idlula kumbhede wesisefo samangqamuzana ezingeni lokushisa legumbi, amanzi okulandela umkhondo ne-mercaptan ayamuncwa, ngaleyo ndlela kunciphisa amanzi nokuqukethwe kwe-mercaptan kugesi eliphakelayo, kuqaphela inhloso yokuphelelwa amanzi emzimbeni kanye ne-desulfurization. inqubo ye-adsorption ye-sieve yamangqamuzana ivame ukuqhutshwa ekushiseni okuphansi nokucindezela okuphezulu, kuyilapho ukuvuselelwa kwe-desorption kwenziwa ekushiseni okuphezulu nokucindezela okuphansi. Ngaphansi kwesenzo sokushisa okuphezulu, igesi ehlanzekile futhi ephansi yokuvuselela igesi, i-adsorbent ye-molecular sieve ikhulula i-adsorbate ku-micropore ekugelezeni kwegesi yokuvuselela kuze kube yilapho inani le-adsorbate ku-adsorbent lifinyelela ezingeni eliphansi kakhulu, futhi linamandla okumunca amanzi ne-mercaptan kusuka kugesi ophakelayo, ibona inqubo yokuvuselela i-molecular and recycling.
Indlela ye-molecular sieve iwuhlobo lwendlela yokuphelelwa amanzi emzimbeni ejulile, evame ukusetshenziswa enqubweni yokuhlukanisa i-condensation esezingeni eliphansi, njengokululama kwegesi yemvelo ye-condensate (NGL) kanye nenqubo yokuphelelwa amanzi emzimbeni ekukhiqizeni igesi yemvelo ewuketshezi (LNG). Ngaphezu kwalokho, i-molecular sieve dehydration iphinde isetshenziswe ekukhiqizeni igesi yemvelo ecindezelwe ukuze kusetshenziswe uphethiloli wezimoto.

Ukuphelelwa amanzi kwe-molecular sieve ngokuvamile kusebenza kulezi zenzakalo ezilandelayo:
a. Lapho izinga lamazolo legesi yemvelo lidingeka ukuba libe ngaphansi kuka -40 ℃.
b. Ilungele ukulawula indawo yamazolo e-hydrocarbon yegesi yemvelo enomfutho ophakeme.
c. Igesi yemvelo iphelelwa amanzi futhi ihlanzwa ngesikhathi esifanayo.
d. Lapho igesi yemvelo equkethe i-H2S iphelelwa amanzi futhi incibilika ku-glycol, izobangela ukukhishwa kwegesi yokuvuselela.
e. Uma ukuphelelwa amanzi kwe-LPG ne-NGL kudinga ukususa i-trace sulfide (H2S, CO,COS, CS2, mercaptan) ngesikhathi esifanayo.

Ishadi eligelezayo

Izikhangisi zemibhede engaguquki zisetshenziselwa ukukhipha amanzi ngesisefo se-molecular, ngakho-ke iyunithi kufanele okungenani ibe nama-adsorbers amabili, eyodwa esesigabeni sokuqeda amanzi emzimbeni, enye isesigabeni sokuvuselela kanye nokupholisa. Lapho umthamo weyunithi mkhulu kakhulu, inqubo ye-multi tower nayo ingahlelwa.
