Muzvisikwa, kunhuhwirira kwesarufa nesarufa kunowanikwa zvakasikwa kunosanganisira skunk spray nemazai anoora. Mukurumbira wesarufa sechinhu chinonhuhwirira chakaipa wakaita kuti indasitiri yegasi rechisikigo idanidze chero gasi rechisikigo rine sarufa kuti, gasi rinovava. Pamusoro pekunhuhwirira kwaro kunotyisa sarufa inogonawo kuva inouraya kuvanhu kana iine simba rakawanda, uye inoparadzawo. Saka kubviswa kwayo kubva munzizi dzegasi rechisikigo inzira inokosha, inonzi kutapira kwegasi rechisikigo.
Kuti gasi rechisikigo rionekwe serakakora, hydrogen sulfide inofanira kudarika 5.7 milligrams pa cubic mita yegasi rechisikigo. Kutapira kwegasi rechisikigo kunowanzo shandiswa nzira inonzi amine treatment kuti ibvise sarufa kubva munzizi dzegasi. Sarufa ine hukama neamine uye painopfuura nepakati peshongwe ine amine, sarufa inonamira kuamine uye inobviswa munzizi. Kurapa amine kunoshanda zvakafanana nekurapa glycol nekuti ese anoshandisa mvura inonyunguduka kubvisa zvinhu zvisingadiwe uye zvinhu zvinobva munzizi dzegasi rechisikigo.
Sarufa inonhuwirira, inogonawo kubatsira. Semuenzaniso sarufa inowanzo shandiswa mufetereza, machisi, uye mishonga yezvipembenene uye inoshandiswa kugadzira sulfuric acid iyo inoshandiswa mumaindasitiri akawanda. Sarufa inobviswa kubva munzizi dzegasi rechisikigo inogona kuwanikwazve uchishandisa Claus Process uye inotengeswa sechigadzirwa chakasiyana negasi rechisikigo.
Maitiro eClaus ane matanho maviri: danho rekupisa uye danho rekugadzirisa.
Danho rekupisa rakagadzirirwa kushandura hydrogen sulfide yakawanda inobviswa mumhepo inoyerera kuita sarufa yakajairwa. Izvi zvinoitwa nekuisa hydrogen sulfide mumhepo pakupisa kwakanyanya. Inenge 60-70% yesarufa inogadzirwa panguva iyi.
Danho rekugadzira zvinhu rakagadzirirwa kutora hydrogen sulfide yasara nesarufa itsva kuti igadzire sarufa yakawanda nekudzipisa pamwe chete pamusoro pe catalyst, inowanzoitwa activated alumina uye specialty titania. Specialty titania inobatsira kushandura hydrogen sulfide yasara kuita sarufa uye activated alumina inobatsira kudzivirira titania kubva muhupfu hwe sulfation hunokonzerwa ne oxygen inopinda.
Inenge 97% yesarufa inobviswa munzizi dzegasi rechisikigo inotorwa uchishandisa Claus Process. MuChina, inenge 15% yesarufa yese inogadzirwa inotorwa munzizi dzegasi rechisikigo.
