Gasi remuswe rinobva muindasitiri yekuchenesa gasi rechisikigo rinogona kugadziriswa nekuderedza kunyudzwa kwegasi. Nheyo yekuderedza nekunyudzwa kwegasi remuswe ndeyekuisa hydrogenation mugasi remuswe, kuderedza zvikamu zvesarufa mugasi remuswe kuita H2S, kunyudza H2S inogadzirwa nenzira yekusarudza nenzira yeamine, uye pakupedzisira kugadzirazve kana kuburitsa gasi, uye wozopinda muClaus unit kuti ripararire. Maitiro ekuisa hydrogenation ane mari yakawanda uye mutengo wakakwira wekushanda. Zvisinei, anogona kuwana goho resarufa rakawanda, senge rinodarika 99.8%, iro rinoshandiswa zvakanyanya munyika nenzvimbo dzine zvinodiwa zvakanyanya zvekuchengetedza nharaunda.
Nzira yekuderedza kunyudzwa kweropa inosanganisira maitiro anotevera: maitiro eScot, maitiro eHCR, maitiro ekugadzirisazve, maitiro ebsrp uye maitiro eRAR.
Nzira yeScot inonzi Scot inoreva tekinoroji yekurapa gasi remuswe weClaus sulfur plant yeDutch Shell. Kazhinji, nzira yeClaus yechinyakare (yematanho maviri kana matatu) inoshandiswa pakudzoreredza sarufa. Mwero wekudzoreredza sarufa weiyi nzira ungangoita 95% ~ 97%. Munharaunda yanhasi, zvinodiwa zvekuchengetedza zvakatipoteredza zvakakwira zvakanyanya, uye kuburitswa kwemhepo kunobvumidzwa kushoma. Kana unit yekudzoreredza sarufa iine simba rakakura, mwero wekudzoreredza wakakwira kwazvo (99% kana kupfuura). Muchiitiko ichi, super Claus kana Scot tail gas treatment system inofanira kufungwa nezvayo. Zvisinei, kana mwero wekudzoreredza uchidikanwa kusvika kupfuura 99.5%, scot inogona kushandiswa chete.
Maitiro eHCR tekinoroji yemaitiro eHCR yakagadzirwa nekambani yeItaly nigi zvakare rudzi rwemaitiro ekuderedza hydrogenation. Chinhu chikuru chemaitiro aya kushandisa kunonoka kweincinerator uye kupisa kwemapapu kwemaitiro egesi yesulfure kugadzira choto kupisa gasi rekumashure, saka hapana chikonzero chekuwedzera kupisa, kuitira kuti kudzokorodza kupisa kwemarara uye kuderedza zvakanyanya mutengo. Uyezve, maitiro aya haadi hydrogen yakawedzerwa. H2 yakaora neClaus section high temperature combustion furnace yakakwana kuderedza sarufa yasara kuita H2S.
Maitiro eResulf maitiro eResulf akagadzirwa nekambani yeTPA anosanganisira mhando nhatu: maitiro eResulf, maitiro eResulf-10 uye maitiro eResulf mm. Kufanana nemaitiro eScot, gasi remuswe reClaus unit rinotanga rapiswa, rozosanganiswa negasi rekuderedza rinosanganiswa neH2 kuderedza gasi rine sulfur mu reactor kuenda kuH2S. Maitiro aya anogona kushandiswa kuvandudza mwero wekudzoreredza sulfur weClaus unit iripo.
Maitiro eBsrp akagadzirwa pamwe chete neUOP naParsons. Maitiro eBsrp anonyanya kushandiswa pakurapa Claus unit negasi remuswe. Maitiro aya agara achishandiswa pasi rese.
Huwandu hwese hweClaus / bsrp unit hunogona kusvika pa99.8%. Bsrp inoshandisa nzira yeanthrone kuti itore H2S. H2S iri mugasi remuswe rakaburitswa yakaderera, asi kune matambudziko akawanda ekushanda.
Tekinoroji yeRar KTI yakagadzira nzira yekurapa gasi remuswe inonzi rar (kuderedza, kunyudza uye kudzokorodza). Maitiro aya akavakirwa pakuderedza maamines: musimboti wemaitiro aya unozivikanwa zvikuru muindasitiri, unofanana nemaitiro akafanana anoshandiswa mune mamwe mashandisirwo akafanana. Maitiro eRar ane mashandiro akavimbika uye anoshanda, uye mwero wayo wekudzoreredza sulfur unogona kusvika 99.9%. Ndiyo nzira yekudzorera sulfur inoshanda zvakanyanya mune tekinoroji iripo.
