Hidrosulfide sodium laɓɓinoowo: Baɗte e miijooji

E nder gollorɗe petroŋ e kemikal, golle peewnugol ko wayi no distillation vacuum e cracking catalytic ina keewi waɗde gaasuuji asid. Ɗeeɗoo gaasuuji asid ina keewi wonde 85%–95% sulfiid hidrojen (H2S), 3%–10% gaas karbonik (CO2), 2%–5% gaasuuji organik, e 0,5%–3% geɗe goɗɗe.

Refineeji tokoosi e hakkundeeji ina keewi safrude ɗeen gaasuuji asid, tawa ina ɓuuɓna ɗi e 30% e ɓuuɓri sodium (NaOH). NaOH ina hawra e H2S ngam waɗde hidrosulfiid sodium (NaHS). So tawii NaHS e nder ɓuuɓri ndii ina yettoo 30%, ɓuuɓri ndii ina waɗa peeje ɓuuɓri. Caggal nde ndiyam ɗam ɓuuɓtii e ɓuuɓri, NaHS ina ɓeydoo haa 70%, NaHS ɓuuɓɗo oo ina taƴaa e ɓuuɓri.

Kono nde tawnoo gaasuuji asid ɗii ina njogii CO2, ko wayi no karbonaat sodium (Na2CO3) ina peeña e nder safaara, ina usta laaɓal geɗel NaHS ngel.

Yanti heen, so ɓuuɓri udditiindi huutoraama ngam taƴde NaHS ɓuuɓɗo, NaHS ina heewi jokkondirde e oksijen e nder weeyo, ina waɗa tiyosulfaat sodium (Na2S2O3), mo nganndu-ɗaa ina heewi bonnude, ina saɗi mooftude. Slicing udditirɗo kadi ina yaltina gaasuuji ɓuuɓɗi, ina mbonna nokku peewnugol oo.

Ƴeew ɗoo ngam heɓde limre ustaare ngam sodium hydrosulfide, maa won kaawniiɗe.
