Iskidi yonyango lwegesi yomsila

Inkcazo

I-skid yonyango lwegesi yomsila wegesi yendalo isetyenziselwa ikakhulu ukujongana negesi yomsila wesixhobo sokubuyisa isalfure, kunye negesi yenkunkuma yedama lesalfure elimanzi kunye nesixhobo segesi yenkunkuma yeTEG yesixhobo sokubuyisa isalfure.
Uyilo kunye nomthamo wokucubungula weskid uhambelana nesixhobo sokubuyisela isalfure kunye nesixhobo sokuphelisa amanzi emzimbeni.

I-skid yonyango lwegesi yomsila wegesi yendalo inokwahlulwahlulwa ibe ziindidi ezine.

1. Inkqubo yokunciphisa kunye nokufunxa
Umgaqo wenkqubo yokunciphisa nokufunxa kukuba igesi yomsila ibe yihydrogenated, izinto eziqulathe isalfure kwigesi yomsila zincitshiswa zibe yi-H2S, i-H2S evelisiweyo ifunxwa ngokukhetha ngendlela ye-amine, kwaye ekugqibeleni ukuvuselelwa okanye igesi ikhutshwa ukuze ingene kwiyunithi yeClaus yokusabela okujikelezayo. Inkqubo yeHydrogenation inotyalo-mali oluphezulu kunye neendleko eziphezulu zokusebenza, kodwa isetyenziswa kakhulu kumazwe nakwiindawo ezineemfuno eziphezulu zokhuseleko lokusingqongileyo kuba inokufikelela kwisivuno esiphezulu sesalfure, esingaphezulu kwe-99.8%.

2. Inkqubo yokufunxa i-oxidation
Indlela yokufunxa i-oxidation yindlela eqala ngokufunxa i-sulfide kwigesi yomsila ibe yi-SO2, ize ifunxe i-SO2 ngesisombululo (okanye i-solvent), ize ekugqibeleni iyifumane ngohlobo lwe-sulfate, i-sulfide kunye ne-SO2.
Kukho iindlela ezininzi ezizezolu hlobo, uninzi lwazo ezisetyenziselwa ukususa i-flue gas okanye unyango lwe-tail gas evela kwi-smelters kunye ne-sulfuric acid plants, kwaye indlela yeWellman Lord isetyenziselwa unyango lwe-Claus tail gas.

3. Inkqubo yeClaus yobushushu obuphantsi
Itekhnoloji yeClaus ebushushu obuphantsi ibonakaliswa yimpendulo kaClaus engaphantsi kwe-sulfur dew point, ngoko ke ikwabizwa ngokuba yinkqubo yokubuyisela i-sub dew point sulfur. I-Claus reaction yinkqubo enamandla yokusabela ye-exothermic. Ke ngoko, ubushushu obuphantsi bunceda ekutshintsheni kokulingana ukuya kwicala lokuveliswa kwesalfure, okunokuphucula ukubuyiselwa kwesalfure. Ngokwendlela uClaus reaction kunye neyunithi enxulumene ngayo, inkqubo yeClaus ebushushu obuphantsi inokwahlulwa ibe yinkqubo yeClaus ebushushu obuphantsi ezimeleyo kunye nenkqubo yeClaus ebushushu obuphantsi edibeneyo.

4. Inkqubo yokunyibilikisa ngqo kwisigaba solwelo
Inkqubo ye-oxidation ngqo yesigaba solwelo luhlobo lobuchwepheshe benkqubo obudibanisa ngokuthe ngqo i-H2S ibe yi-elemental sulfur. Umgaqo wale nkqubo kukufunxa i-H2S kwigesi yomsila ngesisombululo se-desulfurization, uze uyixube ukuze kuveliswe i-elemental sulfur.

Iiparameter zobugcisa
