Ngokwenyani, kwindalo, amanye amavumba e-sulphur ne-sulphur afumaneka ngokwendalo aquka i-skunk spray kunye namaqanda abolileyo. Udumo lwe-sulphur njengento enuka kakubi luye lwakhokelela kushishino lwegesi yendalo ekubizeni nayiphi na igesi yendalo ene-sulphur, igesi emuncu. Ukongeza kwivumba layo elibi, i-sulphur inokuba yingozi ebantwini xa inamandla ngokwaneleyo, kwaye ikwangcolisa. Ngoko ke ukususwa kwayo kwimithombo yegesi yendalo yinkqubo ebalulekileyo, ebizwa ngokuba yi-natural gas sweetening.
Ukuze igesi yendalo ithathwe njengemuncu, ihydrogen sulfide kufuneka idlule kwi-5.7 milligrams nge-cubic meter yegesi yendalo. Ukulungisa igesi yendalo kudla ngokusebenzisa inkqubo ebizwa ngokuba yi-amine treatment ukuze kususwe i-sulfur kwimijelo yegesi. I-Sulfur ine-affinity kwi-amine kwaye xa idlula kwinqaba equlethe i-amine, i-sulfur inamathela kwi-amine kwaye isuswe kwimijelo. Unyango lwe-amine lusebenza ngendlela efanayo nonyango lwe-glycol kuba zombini zisebenzisa isisombululo solwelo ukususa izinto ezingafunekiyo kunye neekhompawundi kwimijelo yegesi yendalo.
I-sulfur iyanuka, inokuba luncedo. Umzekelo, i-sulfur isetyenziswa rhoqo kwizichumisi, kumatshisi, nakwizibulali-zinambuzane kwaye isetyenziselwa ukwenza i-sulfuric acid enezicelo ezininzi kwimizi-mveliso. I-sulfur esuswa kwimithombo yegesi yendalo inokufunyanwa kusetyenziswa iClaus Process kwaye ithengiswe njengemveliso eyahlukileyo kwigesi yendalo.
Inkqubo yeClaus inamanyathelo amabini: inyathelo lobushushu kunye nenyathelo lokutsala amandla.
Inyathelo lobushushu lenzelwe ukuguqula uninzi lwe-hydrogen sulfide esusiweyo kumjelo wegesi ibe yi-sulfur eqhelekileyo. Oku kwenziwa ngokuxovula i-hydrogen sulfide ngomoya kumaqondo obushushu aphezulu. Malunga ne-60-70% ye-sulfur iveliswa ngeli nyathelo.
Inyathelo le-catalytic lenzelwe ukuthatha i-hydrogen sulfide eseleyo kunye ne-sulfur esandul’ ukwenziwa ukuze zenze i-sulfur engakumbi ngokuzifudumeza kunye phezu kwe-catalyst, edla ngokuba yi-activated alumina kunye ne-specialty titania. I-specialty titania inceda ukuguqula i-hydrogen sulfide eseleyo ibe yi-sulfur kwaye i-activated alumina inceda ukukhusela i-titania kwityhefu ye-sulfation ngenxa yokugqobhoza kwe-oksijini.
Malunga ne-97% yesalfure ekhutshwa kwimisinga yegesi yendalo ifunyanwa kusetyenziswa iClaus Process. ETshayina, malunga ne-15% yayo yonke isalfure evelisiweyo ikhutshwa kwimisinga yegesi yendalo.
