Dalilan rashin kunnawa ƙwayoyin ƙwayoyin cuta a cikin tsarin tsarkakewa na sashin raba iska

1, sakamakon wuce gona da iri na abun ciki na ruwa akan aikin sieve kwayoyin halitta
Babban aikin tsarkakewa na na'urar rabuwar iska shine cire danshi da abun ciki na hydrocarbon daga iska don samar da bushewar iska don tsarin na gaba.Tsarin kayan aikin yana cikin nau'i na gado mai kwance a kwance, ƙananan ƙararrakin alumina da aka kunna shine 590 mm, babba na 13X mai cike da ƙwayar ƙwayar ƙwayar cuta shine 962 mm, kuma ana canza masu tsarkakewa tsakanin juna.Daga cikin su, alumina da aka kunna galibi yana shayar da ruwa a cikin iska, kuma sieve na kwayoyin yana amfani da ka'idar tallan tallan ta kwayoyin don tallata hydrocarbons.Dangane da abun da ke tattare da kayan abu da kaddarorin adsorption na sieve kwayoyin, tsarin tallan shine: H2O> H2S> NH3> SO2> CO2 (tsari na tallan gas na alkaline).H2O> C3H6> C2H2> C2H4, CO2, C3H8> C2H6> CH4 (tsari na adsorption na hydrocarbons).Ana iya ganin cewa yana da mafi ƙarfi aikin adsorption don kwayoyin ruwa.Duk da haka, abin da ke cikin ruwa na sieve kwayoyin ya yi yawa, kuma ruwan kyauta zai haifar da crystallization na ruwa tare da sieve kwayoyin.Za'a iya samar da zafin jiki (220 ° C) ta 2.5pta tururi da aka yi amfani da shi har yanzu ba zai iya cire wannan sashi na kwayoyin kwayoyin halitta ba, saboda haka ba zai iya ci gaba da adsorb hydracack.A sakamakon haka, ƙwayar ƙwayar ƙwayar ƙwayar cuta ta ƙare, an rage rayuwar sabis, kuma kwayoyin ruwa sun shiga cikin ƙananan zafin jiki na tsarin gyaran gyare-gyare, yana haifar da tashar tashar wutar lantarki ta daskare da toshe, yana rinjayar tashar iska. da tasirin canjin zafi na mai musayar zafi, kuma a lokuta masu tsanani, na'urar ba zata iya aiki akai-akai ba.
2. Tasirin H2S da SO2 akan aikin sieve kwayoyin halitta
Saboda zaɓin zaɓi na sieve na ƙwayoyin cuta, ban da babban tallan ƙwayoyin ruwa, kusancinsa ga H2S da SO2 shima ya fi aikin tallan sa na CO2.H2S da SO2 sun mamaye saman mai aiki na simintin ƙwayoyin cuta, kuma abubuwan acidic suna amsawa tare da sieve na ƙwayoyin cuta, wanda zai haifar da sieve na ƙwayoyin cuta da guba da kashewa, kuma ƙarfin adsorption na sieve kwayoyin zai ragu.An gajarta rayuwar sabis na sieve kwayoyin.
A taƙaice, yawan danshi, H2S da SO2 abun ciki na iskar gas a cikin iska mai fita na hasumiya mai sanyaya iska ta rabuwa shine babban dalilin rashin kunna sieve kwayoyin halitta da rage rayuwar sabis.Ta hanyar tsananin kulawa da alamun tsari, ƙari na mai binciken danshi mai tsarkakewa, zaɓi mai dacewa na nau'ikan fungicides, adadin adadin fungicides daidai, hasumiya mai sanyaya ruwa don ƙara ɗanyen ruwa, ƙididdigar samfuri na yau da kullun na zubar da mai mai zafi da sauran matakan, aminci da kwanciyar hankali. Aiki na mai tsarkakewa na iya kunna ganowa akan lokaci, faɗakarwa akan lokaci, dalilai na daidaitawa akan lokaci, zuwa babban adadin don tabbatar da amfani da ingantaccen sieve kwayoyin.
