1. Pulverized coal Mbelata usoro, mirabilite na pulverized coal na-agwakọta na a ruru 100: (21-22.5) (arọ ruru) na calcined na belata na a elu okpomọkụ nke 800-1100 Celsius C, na ihe pụta na-mma na thermally. agbazere n'ime mmiri mmiri na dilute lye , mgbe ọ guzosiri ike maka nkọwa, ihe ngwọta lye dị elu na-elekwasị anya iji nweta sodium sulfide siri ike. A na-enweta ngwaahịa sodium sulfide mbadamba (ma ọ bụ granule) site na tank mbufe, mbadamba (ma ọ bụ granulation)
Usoro mmeghachi omume kemịkalụ: Na2SO4+2C→Na2S+2CO2

2.Absorption usoro: 380-420 g / L sodium hydroxide ngwọta na-eji mmiri na-ekpofu gas nke nwere H2S> 85% hydrogen sulfide, na ngwaahịa enwetara na-ekpochapụ ma tinye uche iji nweta sodium sulfide emechara ngwaahịa.
Usoro mmeghachi omume kemịkalụ: H2S+2NaOH→Na2S+2H2O

3. Usoro Barium sulfide, sodium sulfide nwere ike nweta dị ka ihe na-emepụta mgbe a na-eji sodium sulfate na barium sulfide mee ihe maka mmeghachi omume metathesis iji kwadebe barium sulfate precipitated. Nke ahụ
Usoro mmeghachi omume chemical: BaS+Na2SO4→Na2S+BaSO4↓

4. Gas Mbelata usoro, na ọnụnọ nke iron catalyst, hydrogen (ma ọ bụ carbon monoxide, na-emepụta gas, methane gas) na-meghachi omume na sodium sulfate na a esi ọkụ, na elu-edu anhydrous granular sodium sulfide (nwere Na2S 95%) nwere ike. nweta. ~97%).
Usoro mmeghachi omume kemịkal:
Na2SO4+4CO→Na2S+4CO2
Na2SO4+4H2→Na2S+4H2O

5.Production usoro, usoro nnụcha na-eji sodium sulfide ngwọta na ntinye nke banyere 4% site-product na usoro nke precipitated barium sulfate dị ka akụrụngwa. Mgbe ọ gbasasịrị ya n'ime evaporator nke nwere mmetụta okpukpu abụọ ka ọ pụta na 23%, ọ na-abanye na tankị na-akpali akpali iji wepụ ígwè. , Mgbe ọgwụgwọ mkpochapụ carbon gasịrị, a na-agbanye lye n'ime evaporator (nke a na-eji ihe nickel dị ọcha) na-ekpochapụ ihe ọkụkụ ahụ ka ọ ruo na ntinye uche, ma zigara ya na igwe mbadamba mmiri na-ekpo ọkụ nke drum.

Ụlọ ọrụ anyị na-eji ụzọ abụọ, usoro mbelata coal gbazere na usoro barium sulfide, iji mepụta flakes na-acha uhie uhie sodium sulfide na flakes odo.
