Sodium Hydrosulfide thianhnak: Hnulei le Hmuhning

Petroleum le chemical industry ah, vacuum distillation le catalytic cracking tibantuk thianhnak riantuannak nih a tlangpi in acidic gas a chuahter. Hi acidic gas pawl hi a tlangpi in 85%-95% hydrogen sulfide (H2S), 3%-10% carbon dioxide (CO2), 2%-5% organic gas pawl, le 0.5%-3% a dang thilri hna an si.

A hmete le a tlawm deuhmi thianhnak sehzung hna nih hi acidic gas pawl hi 30% sodium hydroxide (NaOH) cawhmi in an hnim tawn hna. NaOH cu H2S he aa pehtlaih i a ser sodium hydrosulfide (NaHS). NaHS tlawmtam cu cawhmi chung i 30% a phak tikah, cawhmi cu tlawmternak kalning a kal. Ti tlawmternak le tlawmternak hnu ah, NaHS dat cu 70% tiang a karh, cun a lummi NaHS cu a tthencheu in a tthen.

Sihmanhsehlaw, acidic gas pawl nih CO2 an ngeih caah, thlopnak chungah sodium carbonate (Na2CO3) tibantuk thil thurhnawm pawl an chuak i, NaHS thilchuak thianhlimnak a zorter.

Cun, a lummi NaHS tthennak caah open-drum flakers hman tikah, NaHS nih thli chung i oxygen he aa pehtlaih tawn i, sodium thiosulfate (Na2S2O3) a ser, cucu a rawk kho i chiah a har. Open slicing nih hin thinhunnak a chuahter khomi thli zong a chuahter, thilchuahnak pawngkam kha a thurhnawmhter.

Sodium hydrosulfide caah man tlawm deuh hmuh awkah hika hi hmet, khuaruahhar thil a um lai.
