Txoj kev ua tau zoo rau Sodium Hydrosulfide Synthesis Siv Strontium Carbonate

Sodium sulfide thiab Sodium hydrosulfide yog ob yam khoom tau los ntawm alkaline absorption txoj kev kho ammonia synthesis industrial khib nyiab roj. Ob leeg sodium sulfide thiab sodium hydrosulfide muaj kev siv dav. Sodium sulfide tuaj yeem siv rau hauv kev lag luam dyeing los tsim sulfur dyes, hauv kev lag luam metallurgy uas tsis yog ferrous ua tus neeg sawv cev rau cov ores, hauv kev lag luam tawv ua tus neeg sawv cev dehairing rau cov tawv nqaij nyoos, thiab hauv kev lag luam ntawv ua tus neeg sawv cev ua noj rau ntawv. Sodium hydrosulfide tuaj yeem siv rau hauv kev lag luam zas xim rau kev tsim cov organic intermediates, hauv kev lag luam tawv rau dehairing thiab tanning cov tawv nqaij nyoos, thiab hauv kev lag luam chiv rau kev tshem tawm monomer sulfur ntawm activated carbon cov tshuaj desulfurizer.

Sodium hydrosulfide yog ib yam tshiab ntawm cov khoom siv raw khoom tsim tom qab sodium sulfide, thiab nws feem ntau tshwm sim li HS⁻ ions hauv dej. Nws cov tshuaj aqueous muaj qis dua alkalinity piv rau sodium sulfide, thiab nws nthuav tawm cov ntawv thov kev ua tau zoo hauv kev lag luam teeb, tshuaj lom neeg kev lag luam, thiab lwm yam. Piv txwv li, nws yog siv los ua raw khoom los ua ammonium sulfide thiab ethyl mercaptan; nyob rau hauv kev lag luam mining, nws yog dav siv nyob rau hauv tooj liab ore beneficiation.

Tam sim no, feem ntau cov lag luam ua haujlwm los ntawm kev sau cov roj hydrogen sulfide thiab carbon dioxide generated thaum lub sij hawm npaj strontium carbonate, xyuas kom meej tias cov roj hydrogen sulfide thiab cov pa roj carbon dioxide muaj qee qhov kev xav tau thiab cov kev ntxhov siab ua ntej muab lawv tso rau hauv cov tshuaj alkaline rau cov tshuaj tiv thaiv. Qhov no txhais tau hais tias cov txheej txheem npaj rau strontium carbonate thiab sodium hydrosulfide yog cais, thiab ua ntej kev npaj ntawm sodium hydrosulfide, cov neeg ua haujlwm yuav tsum tau ua ntau yam kev tuav thiab kev tsim cov kauj ruam, ua rau cov txheej txheem kev npaj yuav nyuaj.

Cov txheej txheem ntau lawm

1. Cov tshuaj sodium sulfide aqueous tau nkag mus rau hauv thawj cov tshuaj tiv thaiv ntauwd los ntawm cov pa roj carbon dioxide rov qab ntauwd, thiab carbon dioxide kuj tau nkag mus rau hauv thawj cov tshuaj tiv thaiv ntauwd, qhov twg sodium sulfide aqueous tov thiab carbon dioxide react.

2. Nyob rau hauv kauj ruam (1), lub resulting strontium carbonate, generated hydrogen sulfide gas, thiab unreacted carbon dioxide yog sau thiab reintroduced los ntawm thawj cov tshuaj tiv thaiv ntauwd rau hauv cov pa roj carbon dioxide rov qab ntauwd. Cov pa roj carbon dioxide unreacted reacts nrog sodium sulfide aqueous tov nyob rau hauv carbon dioxide rov qab ntauwd, thaum lub hydrogen sulfide gas nkag mus rau lub thib ob cov tshuaj tiv thaiv pej thuam los ntawm cov pa roj carbon dioxide rov qab ntauwd.

3. Sodium hydroxide alkaline tov yog nkag mus rau hauv lub thib ob cov tshuaj tiv thaiv pej thuam los ntawm hydrogen sulfide rov qab pej thuam, qhov twg cov hydrogen sulfide gas reacts nrog sodium hydroxide alkaline tov nyob rau hauv lub thib ob cov tshuaj tiv thaiv pej thuam.

4. Cov khoom siv sodium hydrosulfide los ntawm cov kauj ruam (3) yog sau, thiab cov roj uas tsis muaj hydrogen sulfide tau rov ua dua tshiab rau hauv hydrogen sulfide rov qab ntauwd kom ua rau cov tshuaj sodium hydroxide alkaline.

Hauv cov ntsiab lus, cov txheej txheem no tuaj yeem ua ntu zus tsim cov strontium carbonate thiab sodium hydrosulfide, ua kom pom cov txheej txheem zoo txuas ntxiv thiab ua tiav cov khoom siv raw thiab cov khoom siv rov ua dua tshiab. Tsis tas li ntawd, cov txheej txheem no ua kom yooj yim rau kev npaj ntawm sodium hydrosulfide los ntawm kev txo cov kev xav tau rau ntau qhov nruab nrab tuav thiab cov txheej txheem tsim. Tsis tas li ntawd, nws zoo nqus cov pa roj carbon dioxide thiab hydrogen sulfide gas, tiv thaiv hydrogen sulfide los ntawm kev tso tawm rau hauv qhov chaw thiab ua rau huab cua muaj kuab lom.
