Ihe kpatara molekụla sieve inactivation na usoro nchacha nke ikuku nkewa

1, mmetụta nke oke ọdịnaya mmiri na ọrụ sieve molecular
Ọrụ bụ isi nke ihe nkewa nke ikuku ikuku bụ iwepụ mmiri na ọdịnaya hydrocarbon site na ikuku iji nye ikuku akọrọ maka usoro ndị na-esote. Ihe owuwu akụrụngwa dị n'ụdị akwa akwa kwụ ọtọ, ala arụ ọrụ alumina dị elu bụ 590 mm, elu 13X molecular sieve na-ejuputa dị elu bụ 962 mm, a na-agbanwekwa ihe abụọ ahụ n'etiti ibe ha. N'ime ha, alumina arụ ọrụ tumadi adsorbs mmiri na ikuku, na molekụla sieve na-eji ya molekụla nhọrọ adsorption ụkpụrụ adsorb hydrocarbons. Dabere na ihe mejupụtara ihe mejupụtara ya na akụrụngwa mgbasa ozi nke sieve molecular, usoro mgbasa ozi bụ: H2O> H2S> NH3> SO2> CO2 (usoro mgbasa ozi nke gas alkaline). H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4 (usoro nke adsorption nke hydrocarbons). Enwere ike ịhụ na ọ nwere arụmọrụ adsorption kachasị ike maka ụmụ irighiri mmiri. Otú ọ dị, ihe dị n'ime mmiri nke sieve molecular dị oke elu, na mmiri efu ga-eme ka mmiri kristal na sieve molecular. Okpomọkụ (220 Celsius C) nke 2.5MPa na-enye uzuoku nke eji eme ka okpomọkụ dị elu ka na-enweghị ike iwepụ akụkụ a nke mmiri kristal, na pore size nke molekul sieve na-eji kristal mmiri molekul, n'ihi ya, ọ pụghị ịnọgide na-adsorb hydrocarbons. N'ihi ya, a na-eme ka sieve molekụla ahụ kwụsị, ndụ ọrụ na-adị mkpụmkpụ, na mmiri mmiri na-abanye n'ime obere efere okpomọkụ nke usoro nhazi nhazi, na-eme ka ọwa mmiri nke ikpo ọkụ na-ekpo ọkụ na-ekpo ọkụ ma na-egbochi, na-emetụta ọwa ikuku. na mmetụta nnyefe okpomọkụ nke onye na-ekpo ọkụ ọkụ, na n'ọnọdụ dị njọ, ngwaọrụ enweghị ike ịrụ ọrụ nke ọma.
2. Mmetụta nke H2S na SO2 na ọrụ sieve molecular
N'ihi mgbasa ozi ahọpụtara nke sieve molecular, na mgbakwunye na mgbasa ozi dị elu nke mkpụrụ ndụ mmiri, njikọ ya maka H2S na SO2 dịkwa mma karịa arụmọrụ mgbasa ozi ya maka CO2. H2S na SO2 na-anọ n'elu arụ ọrụ nke sieve molecular, na akụkụ acidic na-emeghachi omume na sieve molecular, nke ga-eme ka sieve molecular merụọ ma mebie ya, ikike mgbasa ozi nke sieve molecular ga-ebelata. A na-ebelata ndụ ọrụ nke sieve molecular.
Na nchịkọta, oke mmiri ọdịnaya, H2S na SO2 gas ọdịnaya na ntinye ikuku nke ikuku nkewa ikuku jụrụ ụlọ elu bụ isi ihe mere inactivation nke molekụla sieve na shortening nke ọrụ ndụ. Site na njikwa siri ike nke ndị na-egosi usoro, mgbakwunye nke purifier outlet mmiri analyzer, ezi uche nhọrọ nke fungicides ụdị, n'oge quantitative onunu ogwu nke fungicides, mmiri jụrụ ụlọ elu ịgbakwunye raw mmiri, mgbe nile sample analysis nke okpomọkụ Exchanger leakage na ndị ọzọ jikoro, mma na kwụsiri ike. arụ ọrụ nke nchacha nwere ike ịme nchọpụta n'oge, ịdọ aka ná ntị n'oge, ebumnuche mgbanwe n'oge, ruo n'ókè dị ukwuu iji hụ na ojiji nke molecular sieve arụmọrụ.
