Dalilan Rashin Aiki na Sieve na Kwayoyin Halitta a Tsarin Tsaftacewa na Na'urar Raba Iska

1, tasirin yawan ruwa akan aikin sieve na kwayoyin halitta
Babban aikin tsarkake na'urar raba iska shine cire danshi da sinadarin hydrocarbon daga iska don samar da iska mai bushewa ga tsarin da ke gaba. Tsarin kayan aikin yana cikin nau'in gadon kwanciya a kwance, ƙaramin tsayin cika alumina da aka kunna shine 590 mm, saman tsayin cika sieve na kwayoyin halitta 13X shine 962 mm, kuma ana canza masu tsarkakewa guda biyu tsakanin juna. Daga cikinsu, alumina da aka kunna galibi tana sha ruwa a cikin iska, kuma sieve na kwayoyin halitta yana amfani da ƙa'idar shawa ta kwayoyin halitta don shawa hydrocarbons. Dangane da abun da ke ciki da kaddarorin shawa na sieve na kwayoyin halitta, tsarin shawa shine: H2O> H2S> NH3> SO2 > CO2 (tsarin shawa na iskar alkaline). H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4 (tsarin shawa na hydrocarbons). Ana iya ganin cewa yana da ƙarfin aikin shawa ga ƙwayoyin ruwa. Duk da haka, ruwan da ke cikin sieve na kwayoyin halitta ya yi yawa, kuma ruwa mai kyauta zai samar da sieve na ruwa tare da sieve na kwayoyin halitta. Zafin jiki (220 °C) wanda tururin 2.5MPa da ake amfani da shi don sake farfaɗo da zafin jiki mai yawa har yanzu ba zai iya cire wannan ɓangaren ruwan kristal ba, kuma girman ramin sieve na kwayoyin halitta yana mamaye da ƙwayoyin ruwa na kristal, don haka ba zai iya ci gaba da shanye hydrocarbons ba. Sakamakon haka, sieve na kwayoyin halitta ya kashe, tsawon lokacin sabis ɗin ya gajarta, kuma ƙwayoyin ruwa suna shiga cikin mai musayar zafi na farantin mai ƙarancin matsin lamba na tsarin gyarawa, wanda ke haifar da hanyar kwarara ta mai musayar zafi ta daskare ta toshe, tana shafar hanyar iska da tasirin canja wurin zafi na mai musayar zafi, kuma a cikin mawuyacin hali, na'urar ba za ta iya aiki yadda ya kamata ba.
2. Tasirin H2S da SO2 akan aikin sieve na kwayoyin halitta
Saboda zaɓin shaƙar sieve na ƙwayoyin halitta, ban da yawan shaƙar ƙwayoyin ruwa, shaƙar H2S da SO2 ta fi kyau fiye da shaƙar CO2. H2S da SO2 suna mamaye saman sieve na ƙwayoyin halitta, kuma abubuwan da ke ɗauke da acid suna amsawa da sieve na ƙwayoyin halitta, wanda zai sa sieve na ƙwayoyin halitta ya zama guba kuma ya kashe, kuma ƙarfin shaƙar sieve na ƙwayoyin halitta zai ragu. Rayuwar sabis na sieve na ƙwayoyin halitta ta ragu.
A taƙaice, yawan danshi, yawan iskar H2S da SO2 a cikin iskar fita ta hasumiyar sanyaya iskar raba iska shine babban dalilin dakatar da sieve na kwayoyin halitta da kuma rage tsawon lokacin aiki. Ta hanyar tsauraran matakan sarrafa alamun tsari, ƙara na'urar nazarin danshi ta hanyar tsarkakewa, zaɓin nau'ikan fungicides masu dacewa, yawan maganin fungicides akan lokaci, hasumiyar sanyaya ruwa don ƙara ruwan da ba shi da amfani, nazarin samfur akai-akai na zubar da mai musayar zafi da sauran matakai, aikin tsarkakewa mai aminci da kwanciyar hankali na iya taka rawa wajen ganowa akan lokaci, gargaɗi akan lokaci, da kuma daidaita ayyukan, don tabbatar da amfani da ingantaccen sieve na kwayoyin halitta.
