Kwicandelo leenkqubo zoshishino, ukubuyiswa kwesalfure kuye kwavela njengecandelo elibalulekileyo ekukhuthazeni uzinzo lokusingqongileyo kunye nokunciphisa ukukhutshwa komoya okuyingozi. Njengoko amashishini eqhubeka nokukhula, imfuneko yolawulo lwesalfure olusebenzayo iye yaba yinto ebaluleke ngakumbi, ngakumbi kumacandelo afana neoyile negesi, iikhemikhali zepetrochemicals, kunye nezemigodi.

Yintoni iSulfur Recovery?

Ukubuyiswa kwesalfure kubhekisa kwiinkqubo ezisetyenziswayo ukukhupha isalfure kwiimveliso ezahlukeneyo zoshishino, ngakumbi ihydrogen sulfide (H2S). Le khompawundi idla ngokuveliswa ngexesha lokucocwa kweoyile ekrwada kunye negesi yendalo, kunye neenkqubo ezahlukeneyo zokwenza iikhemikhali. Injongo ephambili yokubuyiswa kwesalfure kukuguqula i-H2S ibe yisalfure esisiseko, enokusetyenziswa kwakhona kwiindlela ezahlukeneyo, kubandakanya izichumisi, iikhemikhali, kunye namayeza.

Ukubaluleka Kokubuyiselwa Kwesalfure

1. Ukhuseleko Lokusingqongileyo: Enye yezona nzuzo zibalulekileyo zokubuyiselwa kwesalfure yindima yayo ekunciphiseni ungcoliseko lokusingqongileyo. Ngokubamba nokuguqula i-H2S, amashishini anokunciphisa kakhulu ukukhutshwa kwesalfure, okwaziwa ngokuba negalelo kwimvula ene-asidi kunye neminye imiba yokusingqongileyo. Oku akuncedi nje kuphela ekuthobeleni imithetho engqongqo yokusingqongileyo kodwa kuphucula uzinzo ngokubanzi lwemisebenzi yemizi-mveliso.

2. Ukusebenza kakuhle kwezixhobo: I-Sulfur sisixhobo esixabisekileyo, kwaye ukubuyiselwa kwayo kuvumela amashishini ukuba asisebenzise ngokufanelekileyo. Endaweni yokuba sikhutshwe emoyeni njengegesi eyingozi, i-sulfur efunyenweyo ingasetyenziselwa ukusetyenziswa kwiindawo ezahlukeneyo zoshishino. Oku akugcini nje ngokulondoloza izixhobo zendalo kodwa kukwanegalelo kuqoqosho olujikelezayo apho inkunkuma incitshiswa khona, kwaye izinto ziphinda zisetyenziswe.

3. Iingenelo zoqoqosho: Ukusebenzisa iinkqubo zokubuyisa isalfure kunokukhokelela ekongeni iindleko ezinkulu kumashishini. Ngokuguqula inkunkuma ibe yimveliso esebenzisekayo, iinkampani zinokunciphisa iindleko zazo zokusebenza kwaye zivelise imithombo yengeniso eyongezelelweyo ekuthengisweni kwesalfure efunyenweyo. Ngaphezu koko, ukutyala imali kubuchwepheshe bokubuyisa isalfure kunokuphucula udumo lwenkampani njengeshishini elinoxanduva nelikhathalela okusingqongileyo, litsale abathengi kunye nabatyali-mali ngokufanayo.

Uphuhliso lweTekhnoloji ekuBuyiselweni kweSulfur

Inkqubo yokubuyisa isalfure ibone inkqubela phambili ebalulekileyo kubuchwepheshe kule minyaka idlulileyo. Iindlela zemveli, ezifana nenkqubo yeClaus, ziye zaphuculwa kwaye zaphuculwa ukuphucula ukusebenza kakuhle nokunciphisa iindleko. Ubuchwepheshe obutsha, kuquka iinkqubo zeSuperClaus kunye ne-LO-CAT, bubonelela ngamanqanaba okubuyisela aphuculweyo kunye nokukhutshwa komoya okuphantsi, okwenza kube ziindlela ezinomtsalane kwizicelo zanamhlanje zoshishino.

Ngaphezu koko, ukuhlanganiswa kwetekhnoloji yedijithali kunye nokusebenza ngokuzenzekelayo kwiinkqubo zokubuyisa isalfure kuphucule ngakumbi ukusebenza kakuhle. Ukubeka esweni ngexesha langempela kunye nohlalutyo lwedatha kuvumela ukwenza izigqibo ngcono kunye nokuphucula inkqubo, kuqinisekisa ukuba imisebenzi yokubuyisa isalfure isebenza kakuhle nangokufanelekileyo.

Isiphelo

Njengoko amashishini ejongene noxinzelelo olukhulayo lokwamkela iindlela ezizinzileyo, ukubuyiswa kwesalfure kugqama njengenkqubo ebalulekileyo engagcini nje ngokunciphisa impembelelo yokusingqongileyo kodwa ikwaphucula ukusebenza kakuhle kwezixhobo kunye nokuphila kakuhle kwezoqoqosho. Ngokutyala imali kubuchwepheshe obuphambili bokubuyiswa kwesalfure, iinkampani zinokuzibeka njengeenkokheli ekuzinzeni ngelixa zinegalelo kwikamva elicocekileyo neliluhlaza. Ukwamkela ukubuyiswa kwesalfure akuyomfuneko nje yomthetho; linyathelo elicwangcisiweyo eliya kwindawo yezoshishino ezinzileyo nenoxanduva.
