Indlela Ephumelelayo Ye-Sodium Hydrosulfide Synthesis Ukusebenzisa I-Strontium Carbonate

I-sodium sulfide kanye I-sodium hydrosulfide yimikhiqizo emibili etholwe ngendlela yokumunca i-alkali yokwelapha i-ammonia synthesis igesi yezimboni. Kokubili i-sodium sulfide ne-sodium hydrosulfide zinezicelo ezibanzi. I-sodium sulfide ingasetshenziswa embonini kadayi ukwenza odayi besulfure, embonini yensimbi engenansimbi njenge-ejenti yokuntanta yezinsimbi eziyigugu, embonini yesikhumba njenge-ejenti yokususa uboya besikhumba esingavuthiwe, kanye nasembonini yephepha njenge-ejenti yokupheka yephepha. I-Sodium hydrosulfide ingasetshenziswa embonini yodayi ekwenzeni izinto eziphilayo, embonini yesikhumba yokususa uboya nokushiswa kwesikhumba sesikhumba esingavuthiwe, kanye nasembonini yomanyolo wokususa i-monomer sulphur ku-activated I-Carbon ama-desulfurizer.

I-Sodium hydrosulfide iwuhlobo olusha lwamakhemikhali asetshenziswayo akhiqizwa ngemva kwe-sodium sulfide, futhi itholakala kakhulu njengama-HS⁻ ions emanzini. Isixazululo saso esinamanzi sine-alkalinity ephansi uma siqhathaniswa ne-sodium sulfide, futhi sibonisa ukusebenza okuphezulu kwesicelo embonini yokukhanya, imboni yamakhemikhali, nakweminye imikhakha. Isibonelo, isetshenziswa njengempahla eluhlaza yokukhiqiza i-ammonium sulfide ne-ethyl mercaptan; embonini yezimayini, isetshenziswa kakhulu ekuzuzeni i-copper ore.

Njengamanje, amabhizinisi amaningi asebenza ngokuqoqa igesi ye-hydrogen sulfide kanye ne-carbon dioxide ekhiqizwa ngesikhathi sokulungiswa i-strontium carbonate, iqinisekisa ukuthi igesi ye-hydrogen sulfide ne-carbon dioxide inokugxila okuthile nezingcindezi ngaphambi kokuba ikwethule esixazululweni se-alkali ukuze siphendule. Lokhu kusho ukuthi izinqubo zokulungiselela i-strontium carbonate ne-sodium hydrosulfide zihlukene, futhi ngaphambi kokulungiswa kwe-sodium hydrosulfide, izisebenzi zidinga ukwenza izinyathelo eziningi zokuphatha nokubunjwa okuphakathi nendawo, okwenza inqubo yokulungiselela ibe nzima kakhulu.

Izinyathelo Zokukhiqiza

1. Isixazululo esinamanzi se-sodium sulfide singeniswa embhoshongweni wokusabela wokuqala ngombhoshongo wokubuyisela i-carbon dioxide, kanye ne-carbon dioxide futhi yethulwa embhoshongweni wokusabela wokuqala, lapho i-sodium sulfide isixazululo samanzi kanye ne-carbon dioxide isabela.

2. Esinyathelweni (1), umphumela we-strontium carbonate, igesi ye-hydrogen sulfide ekhiqizwe, kanye ne-carbon dioxide engaphenduliwe iyaqoqwa futhi iphinde ifakwe embhoshongweni wokusabela wokuqala embhoshongweni wokubuyisela isikhutha. I-carbon dioxide engaphenduliwe isabela nesisombululo samanzi se-sodium sulfide embhoshongweni wokubuyisela i-carbon dioxide, kuyilapho igesi ye-hydrogen sulfide ingena embhoshongweni wokusabela wesibili ngombhoshongo wokutakula we-carbon dioxide.

3. Isixazululo se-alkaline ye-sodium hydroxide singeniswa embhoshongweni wokusabela wesibili ngombhoshongo we-hydrogen sulfide recovery, lapho igesi ye-hydrogen sulfide isabela nesisombululo se-alkali ye-sodium hydroxide kumbhoshongo wesibili wokusabela.

4. Umkhiqizo we-sodium hydrosulfide kusukela kusinyathelo (3) uyaqoqwa, futhi igesi ye-hydrogen sulfide engaphenduliwe iphinde ifakwe embhoshongweni wokubuyisela i-hydrogen sulfide ukuze isabele ngesisombululo se-alkaline ye-sodium hydroxide.

Kafushane, le nqubo ingakhiqiza ngokulandelana i-strontium carbonate ne-sodium hydrosulfide, ebonisa ukuqhubeka kwenqubo enhle nokufeza ukugaywa kabusha kwezinto ezingavuthiwe nemikhiqizo. Ukwengeza, le nqubo yenza lula ukulungiswa kwe-sodium hydrosulfide ngokunciphisa isidingo sezinyathelo eziningi zokuphatha ezimaphakathi kanye nokubunjwa. Ngaphezu kwalokho, imunca ngempumelelo i-carbon dioxide negesi ye-hydrogen sulfide, ivimbele i-hydrogen sulfide ukuthi ingakhishelwa emkhathini futhi ibangele ukungcoliswa komoya.
