Kuna tindlela timbirhi letikulu to humelerisa sodium sulfide. Ndlela ya Glauber’s salt yikatsa ku hlanganisiwa ka sodium sulfate na coal powder hi 1:0.5 ratio naku hisa eka reverberatory furnace kuya eka 950°C, laha ku tshamaka ku hlanganisiwa ku sivela ku hlangana. Gasi ya hayidirojeni sulfide ya xiendliwa xa le tlhelo yi fanele ku amukeriwa hi ku tirhisa xitofu xa alkaline, naswona ku tsandzeka ku fikelela swipimelo swa vutshunguri bya gasi leyi humesiwaka swi nga endla leswaku ku hakerisiwa tihakelo ku suka eka valawuri va mbango. Ndlela ya by-product yitirhisa mati ya thyaka kusuka eka vuhumelerisi bya munyu wa barium, leswi lavaka magoza ya ntlhanu ya filtration. Loko leswi swihunguta ku durha hi 30%, ku basa kunga fika ntsena eka 90%.

Sodium sulfide yi hlawula switirhisiwa swa xiyimo xale henhla swa raw naswona yi lawula swinene vuhumelerisi hiku tirhisa thekinoloji yale henhla, na vutengi byale henhla xikan’we na thyaka ritsongo, leswi tiyisisaka mphakelo lowu tiyeke hambi kuri eka ti oda letikulu. Click laha ku kuma sodium sulfide ya xiyimo xale henhla na vukorhokeri byale henhla.
