Njira Yabwino Yopangira Sodium Hydrosulfide Synthesis Pogwiritsa Ntchito Strontium Carbonate

Sodium sulfide ndi Sodium hydrosulfide ndi zinthu ziwiri zomwe zimapezeka kudzera mu njira yoyamwitsa ya alkaline pochiza mpweya wotayira wa ammonia. Sodium sulfide ndi sodium hydrosulfide zonse zimagwiritsidwa ntchito kwambiri. Sodium sulfide ingagwiritsidwe ntchito mumakampani opanga utoto popanga utoto wa sulfure , mumakampani opanga zitsulo zopanda chitsulo ngati choyatsira miyala, mumakampani opanga zikopa ngati choyatsira tsitsi la zikopa zosaphika, komanso mumakampani opanga mapepala ngati chophikira mapepala. Sodium hydrosulfide ingagwiritsidwe ntchito mumakampani opanga utoto popanga zinthu zachilengedwe, mumakampani opanga zikopa kuti zichotse tsitsi ndi kupukuta zikopa zosaphika, komanso mumakampani opanga feteleza kuti zichotse sulfure ya monomer kuchokera ku activated Carbon desulfurizers.

Sodium hydrosulfide ndi mtundu watsopano wazinthu zopangira mankhwala opangidwa pambuyo pa sodium sulfide, ndipo umapezeka makamaka ngati ma HS⁻ ions m'madzi. Yankho lake lamadzi lili ndi alkalinity yotsika poyerekeza ndi sodium sulfide, ndipo likuwonetsa magwiridwe antchito apamwamba pamafakitale opepuka, makampani opanga mankhwala, ndi magawo ena. Mwachitsanzo, amagwiritsidwa ntchito ngati zopangira popanga ammonium sulfide ndi ethyl mercaptan; m'mafakitale amigodi, amagwiritsidwa ntchito kwambiri mu copper ore beneficiation.

Pakadali pano, mabizinesi ambiri amagwira ntchito posonkhanitsa mpweya wa hydrogen sulfide ndi carbon dioxide wopangidwa panthawi yokonzekera strontium carbonate , kuonetsetsa kuti mpweya wa hydrogen sulfide ndi carbon dioxide zili ndi kuchuluka ndi kupsinjika kwina asanaziike mu yankho la alkaline kuti zichitike. Izi zikutanthauza kuti njira zokonzekera strontium carbonate ndi sodium hydrosulfide ndizosiyana, ndipo asanakonzekere sodium hydrosulfide, ogwira ntchito ayenera kuchita njira zambiri zogwirira ntchito ndi kupanga, zomwe zimapangitsa kuti njira yokonzekera ikhale yovuta kwambiri.

Njira Zopanga Zopanga

1. The sodium sulfide amadzimadzi njira umalowetsedwa mu woyamba anachita nsanja kudzera mpweya woipa kuchira nsanja, ndi mpweya woipa nawonso anadzetsa woyamba anachita nsanja, kumene sodium sulfide amadzimadzi njira ndi mpweya woipa amachita.

2. Mu sitepe (1), chifukwa strontium carbonate, kwaiye mpweya hydrogen sulfide, ndi unreacted mpweya woipa amasonkhanitsidwa ndi reintroduced kuchokera woyamba anachita nsanja mu mpweya woipa kuchira nsanja. Mpweya wosasunthika wa carbon dioxide umakhudzidwa ndi njira yamadzimadzi ya sodium sulfide mu nsanja ya carbon dioxide recovery, pamene mpweya wa hydrogen sulfide umalowa munsanja yachiwiri yochitira nsanja kudzera mu nsanja ya carbon dioxide recovery.

3. Sodium hydroxide alkaline solution imalowetsedwa mu nsanja yachiwiri yomwe imachitika kudzera mu nsanja ya hydrogen sulfide, pomwe mpweya wa hydrogen sulfide umakumana ndi yankho la sodium hydroxide alkaline mu nsanja yachiwiri.

4. Mankhwala a sodium hydrosulfide kuchokera ku sitepe (3) amasonkhanitsidwa, ndipo mpweya wa hydrogen sulfide wosasunthika umalowetsedwanso mu nsanja ya hydrogen sulfide recovery to make ndi sodium hydroxide alkaline solution.

Mwachidule, njirayi imatha kupanga sequentially kupanga strontium carbonate ndi sodium hydrosulfide, kuwonetsa kupitiliza kwa njira yabwino ndikukwaniritsa zobwezeretsanso zopangira ndi zinthu. Kuphatikiza apo, njirayi imathandizira kukonza kwa sodium hydrosulfide pochepetsa kufunikira kwa masitepe ambiri apakatikati ndikuwongolera. Kuphatikiza apo, imayamwa bwino mpweya woipa wa carbon dioxide ndi hydrogen sulfide, kulepheretsa kuti hydrogen sulfide isatulukire mumlengalenga ndikupangitsa kuti mpweya uwonongeke.
