Isivimbo se-molecular silve sokuphelelwa amanzi emzimbeni

Incazelo

I-molecular sieve dehydration skid iyithuluzi elibalulekile ekuhlanzeni igesi yemvelo noma ekulungiseni igesi yemvelo. I-molecular sieve iyikristalu ye-alkali metal aluminosilicate enesakhiwo sohlaka kanye nesakhiwo esifanayo se-microporous. Lapho igesi yokudla equkethe amanzi amancane idlula embhedeni wesihlungo se-molecular ekushiseni kwegumbi, amanzi amancane kanye ne-mercaptan kuyamuncwa, ngaleyo ndlela kunciphisa amanzi kanye nokuqukethwe kwe-mercaptan kugesi yokudla, kufezwe injongo yokuphelelwa amanzi kanye nokukhishwa kwe-sulfurization. inqubo yokumuncwa kwesihlungo se-molecular ivame ukwenziwa ekushiseni okuphansi kanye nokucindezela okuphezulu, kuyilapho ukuvuselelwa kokumuncwa kwenziwa ekushiseni okuphezulu kanye nokucindezela okuphansi. Ngaphansi kwesenzo segesi yokuvuselelwa kwezinga lokushisa eliphezulu, ehlanzekile nephansi, i-molecule sieve adsorbent ikhipha i-adsorbate ku-micropore ekugelezeni kwegesi yokuvuselelwa kuze kube yilapho inani le-adsorbate ku-adsorbent lifinyelela ezingeni eliphansi kakhulu, futhi linamandla okumunca amanzi kanye ne-mercaptan kugesi yokudla, kufezwe inqubo yokuvuselelwa kanye nokuvuselelwa kwesihlungo se-molecular.
Indlela yokuhluza ama-molecule iwuhlobo lwendlela yokuphelelwa amanzi emzimbeni ngokujulile, evame ukusetshenziswa enkambisweni yokuhlukaniswa kokuhluza okuphansi kwezinga lokushisa, njengenqubo yokululama kanye nokuphelelwa amanzi emzimbeni ngegesi yemvelo ekukhiqizweni kwegesi yemvelo encibilikisiwe (i-LNG). Ngaphezu kwalokho, ukuphela kwamanzi emzimbeni nge-molecular sieve kusetshenziswa nasekukhiqizweni kwegesi yemvelo ecindezelwe yephethiloli yezimoto.

Ukuphelelwa amanzi emzimbeni ngesihlungo sama-molecular kuvame ukusebenza kulezi zikhathi ezilandelayo:
a. Lapho iphuzu lamazolo legesi yemvelo lidingeka khona libe ngaphansi kuka -40 ℃.
b. Ifanele ukulawula iphuzu lama-hydrocarbon dew legesi yemvelo engenamandla aphezulu.
c. Igesi yemvelo iyasuswa amanzi emzimbeni futhi ihlanzwe ngesikhathi esifanayo.
d. Uma igesi yemvelo equkethe i-H2S iphelelwa amanzi emzimbeni futhi incibilikiswa ku-glycol, izobangela ukukhishwa kwegesi yokuvuselela.
e. Uma i-LPG kanye ne-NGL zidinga ukususa i-trace sulfide (H2S, CO,COS, CS2, mercaptan) ngesikhathi esisodwa, ukuphelelwa amanzi emzimbeni kudinga.

Ishadi lokugeleza

Ama-adsorber ebhedi aqinile asetshenziselwa ukuqeda ukuphelelwa amanzi ngesihlungo sama-molecule, ngakho-ke iyunithi kufanele okungenani ibe nama-adsorber amabili, elilodwa esigabeni sokuphelelwa amanzi emzimbeni, elinye esigabeni sokuvuselelwa kanye nokupholisa. Uma umthamo weyunithi mkhulu kakhulu, inqubo yemibhoshongo eminingi nayo ingahlelwa.
