Birta birta u adkeysata daxalka Hydrogen sulfide ee inta badan loo isticmaalo soo saarista iyo qaadista dhuumaha gaaska dhanaan.Iyada oo hagaajinta cadaadiska gaarsiinta iyo in la yareeyo gaaska ka aragtida kharashka desulfurization, mararka qaarkood iyada oo aan desulfurization ee xaaladaha dhuumaha gaaska, si dhuumaha sida u leeyihiin in ay isticmaalaan caabbinta daxalka dhuumaha in hydrogen sulfide.
Hydrogen sulfide birta u adkaysata daxalkadhuumaha saliiddaiyo dhuumaha gaaska ayaa ah kuwa ugu adag in la soo saaro nooc ka mid ah birta, sababtoo ah daahirsanaanta birta dhalaalaysa, kontaroolada kala soocida billet iyo rogid la xakameeyey iyo shuruudaha qaboojinta ee hababka macdanta dhaqameed ee sare ma buuxin karaan shuruudaha.

Caadi ahaan deegaanka gaaska aashitada ah, sababaha dhuumaha dhuumaha ee fashilma waa laba: mid waa dildilaaca daxalka sulfide stress, oo loo gudbiyo SSC.Ciladdu waxay ku jirtaa dusha birta xoogga sare leh iyo walbahaarka gudaha iyo daxalka hydrogen sulfide ee hoos yimaada ficilka dhexdhexaadka ah oo ay weheliyaan jihada walaaca ee derbiga toosan.Dhuumaha habka adeegga, dhuumaha birta heerka sare ah ee u nugul SSC.

Mid kale waa dildilaaca ay keentay hydrogen, oo loo tixraaco HIC.dildilaaca ay sabab u fiirsashada sare ee deegaanka gaaska hydrogen sulfide galay daxalka birta gudaha hydrogen ka soo saaray agagaarka ka mid ah iyo kala soocidda taasoo keentay kobcinta ee dusha la siman dildilaaca derbiga.HIC waxay ku dhacdaa inta badan birta-hooseeya, xoog dhexdhexaad ah oo la beeray.
