Skid ɗin Zaki na Gas yana Haɗa Desulphurization na Molecular Sieve da Dehydration na TEG don Shuke-shuken LNG na Zamani na Gaba
Yayin da masana'antar iskar gas ta duniya (LNG) ke ci gaba da himma wajen samar da ingantattun bayanai na tsafta a shekarar 2026, simintin mai sanyaya iskar gas ya rikide zuwa cibiyar da aka haɗa gaba ɗaya kafin a fara magani, yana haɗa ingantaccen cire sulphurization na sieve na ƙwayoyin halitta tare da na'urar bushewar iskar gas ta TEG don samar da iskar gas mai bushewa sosai, mara sulfur don samar da ruwa mai gudana.
A al'ada, tsarin da aka yi da amine yana sarrafa cire iskar gas mai yawan acid, amma yanzu haka tsarin zaki na gas ya ƙunshi wani abu da ake kira "bulk acid".Desulphurization na kwayoyin halitta Layer—ta amfani da zeolites na roba tare da girman ramuka masu sarrafawa daidai—don goge kwararar iskar gas ta hanyar shaye sauran mercaptans, COS, da kuma bin diddigin H₂S zuwa matakan sub-ppm. Wannan zurfin cire sulphurization yana da mahimmanci ga masu musayar zafi na LNG, inda ko da ƙananan mahaɗan sulfur na iya haifar da samuwar tauri da gurɓatawa a -162 °C.
Tare da wannan gadon sieve na kwayoyin halitta, akwai na'urar bushewar iskar gas ta TEG, wacce ke amfani da triethylene glycol don shan tururin ruwa, yana cimma matsayar ma'aunin dew na 40–60 °C da kuma rage yawan ruwa zuwa ƙasa da 0.1 lb/MMscf. Lokacin da aka shirya a jere akan side ɗin sieve guda ɗaya, haɗin sieve na sieve na Molecular da jerin bushewar TEG yana tabbatar da cewa iskar gas da aka yi wa magani ta cika buƙatun bututun mai da LNG ba tare da buƙatar jiragen ruwa daban-daban masu cinye sarari ba.
Bayanan da aka samu kwanan nan daga wani babban kamfanin samar da iskar gas na kudu maso gabashin Asiya sun nuna cewa maye gurbin na'urori masu zaman kansu da wani simintin gas mai hade da iskar gas ya rage sawun ƙafa da kashi 35% kuma ya rage yawan amfani da makamashin sake farfadowa da kusan kashi 20%. Masu aiki kuma suna amfana daga kayan aiki da aka raba, bawuloli masu canza yanayi ta atomatik, da kuma madaurin iskar gas na sake farfadowa wanda ke inganta ingancin zafi.
"Da yake ana aiwatar da ƙa'idojin hayaki mai tsauri a wannan shekarar, simintin mai na iskar gas ba wai kawai kayan haɗi ne na musamman ba - shine zuciyar ayyukan tashar LNG mai inganci," in ji wani babban injiniyan sarrafawa a wani babban kamfanin EPC. "Simintin simintin sieve na ƙwayoyin halitta yana ba da gogewa ta ƙarshe, yayin da simintin sieve na ƙwayoyin halitta ke ba da gogewa ta ƙarshe, yayin da simintin ... Na'urar bushewar iskar gas ta TEG yana tabbatar da aikin hana daskarewa; tare, suna samar da jirgin ƙasa mai ƙarfi kafin a fara magani wanda ke haɓaka lokacin aiki na ruwa.
