I-sodium hydrosulfide (ifomula yamakhemikhali i-NaHS)iyinhlanganisela ebalulekile ye-inorganic esetshenziswa kakhulu emikhakheni yamakhemikhali neyokwenza imithi. Kuyinto eqinile engenambala ukuya kokuphuzi kancane engancibilika ngokushesha emanzini ukuze yakhe ingxube ye-alkaline equkethe ama-HS^- ions. Njengento ene-asidi ebuthakathaka, i-sodium hydrosulfide inezakhiwo ezinamandla zokunciphisa kanye nezakhiwo eziguquguqukayo.

Inqubo yokukhiqiza ye-sodium hydrosulfide liquid iyinqubo eyinkimbinkimbi edinga ukucatshangelwa okuphelele kwezinto ezifana nezimo zokusabela, ukukhethwa kwemishini, nokuphepha. Nawa amanye amaphuzu wezobuchwepheshe abalulekile:

1. Ukulungiswa kwempahla eluhlaza: Ukulungiswa kwe-sodium hydrosulfide kusebenzisa ukusabela kwesulfure ne-hydrogen, ngakho-ke isibabule ne-hydrogen eyanele kudingeka kulungiswe. Isibabule kufanele sibe nokuhlanzeka okuphezulu ukuze kuqinisekiswe ikhwalithi yomkhiqizo wokugcina. Ukunikezwa kwe-hydrogen kumele futhi kuzinze futhi kuthembeke ukuze kuqinisekiswe inqubekelaphambili eqhubekayo yenqubo yokusabela.

2. Ukukhethwa kwedivayisi esabelayo: Ukulungiswa kwe-sodium hydrosulfide ngokuvamile kusebenzisa i-sodium hydroxide nesibabule ukuze kusabele emazingeni okushisa aphezulu. Ukuze kugcinwe ukusebenza kahle nokuphepha kokusabela, kuyadingeka ukukhetha idivayisi efanele yokusabela. Inketho evamile ukusebenzisa i-reactor eshisayo ukuze kube lula ukusabela ngokulawula izinga lokushisa nokucindezela.

3. Ukulawulwa kwezimo zokusabela: Enqubweni yokulungiselela i-sodium hydrosulfide, izinga lokushisa lokuphendula kanye nesikhathi sokuphendula yizici ezimbili ezibalulekile. Ukushisa okufanelekile kokusabela kungakhuthaza ukusabela futhi kusheshise ukukhiqizwa kwemikhiqizo. Ngesikhathi esifanayo, ukulawulwa kwesikhathi sokuphendula kungathinta nokuhlanzeka kanye nesivuno se-sodium hydrosulfide.

4. Ukulawulwa kwenqubo yokusabela: Ngesikhathi sokulungiswa kwe-sodium hydrosulfide, ukunakwa kufanele kukhokhwe ekuphepheni ngesikhathi sokusabela. I-hydrogen iyavutha futhi iyaqhuma, ngakho-ke i-reactor kufanele ivalwe kahle ngesikhathi sokusabela ukuvimbela ukuvuza kwe-hydrogen. Ngesikhathi esifanayo, ukucindezela kwegesi ku-reactor kufanele kulawulwe ngokuqinile ukuze kugwenywe ukuphuka kwemishini okubangelwa ukucindezela okukhulu.

5. Ukuhlukaniswa nokuhlanza umkhiqizo: Uketshezi olulungisiwe lwe-sodium hydrosulfide ludinga ukuhlukaniswa nezinyathelo zokuhlanza ukuze kukhishwe ukungcola nezinto ezingancibiliki. Izindlela ezijwayelekile zokuhlukanisa zihlanganisa ukuhlunga, ukuhwamuka kanye nekristalu. Lezi zinyathelo zithuthukisa ukuhlanzeka nokuzinza kwe-sodium hydrosulfide, iqinisekisa ukwethembeka kwayo ekusetshenzisweni okulandelayo.

Kufanele kugcizelelwe ukuthi izinqubo ezifanele zokusebenza zokuphepha kufanele zilandelwe ngesikhathi sokulungiswa kwe-sodium hydrosulfide ukuze kuqinisekiswe ukuphepha kwabaqhubi kanye nemvelo. Isibonelo, kufanele ugqoke okokuvikela okufanele ngesikhathi sokusebenza futhi unake imininingwane yokusebenza ukuze uvimbele izingozi.

Sekukonke, inqubo yokukhiqiza kanye namaphuzu ezobuchwepheshe e-sodium hydrosulfide liquid kuhlanganisa izici eziningi ezifana nokulungiswa kwempahla eluhlaza, ukukhethwa kwedivayisi yokusabela, ukulawulwa kwesimo sokusabela, ukulawulwa kwenqubo yokusabela, nokuhlukaniswa nokuhlanza umkhiqizo. Kuphela ngokuwazi kahle la maphuzu ngokwesayensi nangendlela ephusile lapho singakwazi ukukhiqiza uketshezi lwe-sodium hydrosulfide olusezingeni eliphezulu ukuze sihlangabezane nesidingo sale nto emkhakheni wezimboni nakwezemithi.
