Imyuka yo mu mugongo iva mu nganda zitunganya gazi karemano ishobora kuvurwa hakoreshejwe uburyo bwo kugabanya uburyo bwo kuyikuramo. Ihame ryo kugabanya no kuyikuramo ni ugushyiramo hydrogenation kuri gazi yo mu mugongo, kugabanya ibice bya sulfure muri gazi yo mu mugongo kuri H2S, kuyikuramo H2S ikozwe hakoreshejwe uburyo bwa amine, hanyuma ikayikuramo cyangwa ikayishyira mu gice cya Claus kugira ngo ikoreshwe. Uburyo bwo kuyikuramo bufite ishoramari rinini n'ikiguzi kinini cyo kuyikoresha. Ariko, ishobora kugera ku musaruro mwinshi wa sulfure, nko ku kigero kirenga 99.8%, gikoreshwa cyane mu bihugu n'uturere dufite ibisabwa byinshi byo kurengera ibidukikije.
Uburyo bwo kugabanya uburyo bwo kwinjizamo ibintu burimo ahanini inzira zikurikira: Uburyo bwa Scot, uburyo bwa HCR, uburyo bwo kongera gukoresha sulfu, uburyo bwa bsrp na uburyo bwa RAR.
Uburyo bwa Scot, icyo bita Scot, bivuga ikoranabuhanga ryo gutunganya imyuka yo mu murizo w’uruganda rwa Claus sulfur rwo mu Buholandi. Muri rusange, uburyo bwa Claus busanzwe (bw’ibyiciro bibiri cyangwa bitatu) bukoreshwa mu kugarura sulfur. Igipimo cyo kugarura sulfur muri ubu buryo ni hafi 95% ~ 97%. Muri iki gihe, ibisabwa mu kurengera ibidukikije biri hejuru cyane, kandi imyuka yemewe ni mike cyane. Niba icyuma gitunganya sulfur gifite ubushobozi bwinshi, igipimo cyo kugarura ni kinini cyane (99% cyangwa hejuru). Muri iki gihe, hakwiye kwitabwaho uburyo bwo gutunganya super Claus cyangwa Scot tail gaze. Ariko, niba igipimo cyo kugarura gikenewe kugera kuri 99.5%, scot ishobora gukoreshwa gusa.
Uburyo bwa HCR bukoreshwa mu ikoranabuhanga rya HCR ryakozwe n'ikigo cy'Abataliyani cya Nigi, naryo ni uburyo bwo kugabanya hydrogenation. Ikintu nyamukuru cy'ubu buryo ni ugukoresha gutinda gutwika incinerator n'ubushyuhe bw'ibihaha bw'umwuka wo mu itanura rikora sulfur kugira ngo hashyushye gazi y'inyuma, bityo ntihabeho gushyushya by'inyongera, kugira ngo hagerwe ku kongera gukoresha ubushyuhe bw'imyanda no kugabanya cyane ikiguzi. Byongeye kandi, ubu buryo ntibukenera hydrogen y'inyongera. H2 yangiritse na Claus section high temperature irahagije kugira ngo isulfure isigaye igabanuke H2S.
Uburyo bwo kugarura sulfure, uburyo bwo kugarura sulfure bwakozwe na sosiyete ya TPA burimo ubwoko butatu: uburyo bwo kugarura sulfure, uburyo bwo kugarura sulfure-10 na uburyo bwo kugarura sulfure mm. Kimwe na Scot process, gazi yo mu nyito ya Claus ibanza gushyuha, hanyuma ikavangwa na gaze igabanya ivanze na H2 kugira ngo igabanye gaze irimo sulfure muri reactor ibe H2S. Ubu buryo bushobora gukoreshwa mu kunoza igipimo cyo kugarura sulfure muri Claus unit isanzweho.
Uburyo bwa Brp bwateguwe ku bufatanye na UOP na Parsons. Uburyo bwa Brp bukoreshwa cyane cyane mu kuvura imyuka yo mu mugongo ya Claus. Ubu buryo bwakoreshejwe cyane ku isi yose.
Igipimo cyose cyo kugarura sulfur cya Claus / bsrp unit gishobora kugera kuri 99.8%. Bsrp ikoresha uburyo bwa anthrone kugira ngo imenye H2S. Ingano ya H2S mu mwuka wo mu mugongo usohoka ni nke, ariko hari ibibazo byinshi byo gukora.
Ikoranabuhanga rya Rar KTI ryateguye uburyo bwo kuvura imyuka yo mu mugongo bwitwa rar (kugabanya, kwinjiza no kongera gukoresha). Ubu buryo bushingiye ku bintu bigabanya imyuka: ihame ry’uburyo bukoreshwa rirazwi cyane mu nganda, hafi ya ryose nk’uko bigenda mu zindi nzira zisa. Uburyo bwa Rar bufite imikorere yizewe kandi ikora neza, kandi igipimo cyabwo cyo kugarura sulfur gishobora kugera kuri 99.9%. Ni bwo buryo bwiza cyane bwo kugarura sulfur mu ikoranabuhanga ririho.
