Isikhidi sokwelapha igesi yomsila

Incazelo

I-skid yokwelapha igesi yomsila wegesi yemvelo isetshenziswa kakhulu ukubhekana negesi yomsila yedivayisi yokutakula isibabule, kanye negesi engcolile yechibi lesibabule eliwuketshezi kanye nedivayisi yokutakula isibabule engcolile ye-TEG.
Amandla okuklama nokucubungula kwe-skid afaniswa nedivayisi yokubuyisa i-sulfur kanye nedivayisi yokuphelelwa amanzi emzimbeni.

I-skid yokwelapha igesi yomsila wegesi yemvelo ingahlukaniswa ngezigaba ezine.

1. Inqubo yokunciphisa nokumunca
Isimiso senqubo yokunciphisa nokumunca ukuthi igesi yomsila ifakwe i-hydrogen, izingxenye eziqukethe isibabule kugesi yomsila zincishiswa zibe yi-H2S, i-H2S ekhiqizwayo imuncwa ngokukhetha ngendlela ye-amine, bese ekugcineni ukuvuselelwa noma igesi ikhishwa ukuze ingene kuyunithi ye-Claus yokusabela okujikelezayo. Inqubo ye-hydrogenation inotshalomali oluphezulu kanye nezindleko zokusebenza eziphezulu, kodwa isetshenziswa kabanzi emazweni nasezifundeni ezinezidingo eziphezulu zokuvikela imvelo ngoba ingafinyelela isivuno se-sulfur esiphezulu, esingaphezu kuka-99.8%.

2. Inqubo yokumunca i-oxidation
Indlela yokumunca i-oxidation iyindlela eqala ngokumunca i-sulfide kugesi yomsila ibe yi-SO2, bese imunca i-SO2 ngesisombululo (noma i-solvent), bese ekugcineni iyibuyisa ngesimo se-sulfate, i-sulfide kanye ne-SO2.
Kunezindlela eziningi ezihambisana nalolu hlobo, eziningi zazo ezisetshenziselwa ukususa i-flue gas noma ukwelashwa kwegesi yomsila evela ezitshalweni zokuncibilikisa kanye nezitshalo ze-sulfuric acid, kanti indlela ye-Wellman Lord isetshenziselwa ukwelashwa kwegesi yomsila kaClaus.

3. Inqubo ye-Claus yokushisa okuphansi
Ubuchwepheshe be-Claus obusezingeni eliphansi bubonakala ngokusabela kwe-Claus ngaphansi kwephuzu lamazolo le-sulfur, ngakho-ke bubizwa nangokuthi inqubo yokubuyisa i-sulfur engaphansi kwephuzu lamazolo. Ukusabela kwe-Claus kuyinqubo yokusabela enamandla ye-exothermic. Ngakho-ke, izinga lokushisa eliphansi lihambisana nokushintsha kokulingana kuya endleleni yokukhiqizwa kwe-sulfur, okungathuthukisa ukubuyiselwa kwe-sulfur. Ngokusho kobudlelwano phakathi kokusabela kwe-Claus kanye neyunithi, inqubo ye-Claus esezingeni eliphansi ingahlukaniswa ibe inqubo ye-Claus esezingeni eliphansi kanye nenqubo ye-Claus esezingeni eliphansi.

4. Inqubo yokuxilisa ngqo yesigaba soketshezi
Inqubo yokuxilisa ngqo yesigaba soketshezi uhlobo lobuchwepheshe benqubo obufaka i-H2S ngqo ku-sulfur elemental. Isimiso sale nqubo ukumunca i-H2S kugesi yomsila ngesisombululo se-desulfurization, bese uyixuba ukuze ikhiqize i-sulfur elemental.

Amapharamitha obuchwepheshe

1. SO2 ≤ 400mg/Nm3 (isisekelo esomile, 3vol% O2)
2, Isikhathi sokukhiqiza sonyaka amahora angu-8000
3, Ukuguquguquka kokusebenza 50% ~ 120%
