Kurwanya ruswa ya Hastelloy

Hastelloy ni umusemburo wa Ni-Mo ufite karuboni nkeya na silikoni nkeya, bigabanya imvura ya karbide nibindi byiciro muri zone zasuditswe n’ubushyuhe, bityo bigatuma habaho gusudira neza ndetse no muri leta yasudutse.Kurwanya ruswa.Nkuko twese tubizi, Hastelloy afite imbaraga zo kurwanya ruswa mu bitangazamakuru bitandukanye bigabanya, kandi irashobora kwihanganira kwangirika kwa aside hydrochlorike ku bushyuhe ubwo aribwo bwose hamwe n’ubushyuhe ubwo ari bwo bwose.Ifite imbaraga zo kurwanya ruswa muri acide ya sulfurike yo mu rwego rwo hagati, aside irike ya fosifori, aside irike yo mu bushyuhe bwo hejuru, aside irike hamwe na acide kama, aside ya bromic na gaze ya hydrogen chloride.Muri icyo gihe, irwanya kandi ruswa na catalizike ya halogene.Kubwibyo, Hastelloy isanzwe ikoreshwa muburyo butandukanye bwa peteroli na chimique ikarishye, nko gusibanganya no kwibanda kuri aside hydrochloric;alkylation ya Ethylbenzene hamwe na carbonylation yumuvuduko muke wa acide acike nibindi bikorwa.Nyamara, byabonetse mubikorwa byinganda za Hastelloy mumyaka myinshi:

(3) Hastelloy ifite ubushyuhe buke bwumuriro mubushyuhe bwo hagati.Iyo ibyuma biri muri Hastelloy bivanze bigabanutse munsi ya 2%, ibivanze byumva ihinduka ryicyiciro (ni ukuvuga icyiciro cya Ni4Mo, cyateganijwe hagati ya intermetallic).Iyo ibinyomoro bigumye mubushyuhe bwa 650 ~ 750 longer kumwanya muto, β icyiciro gihita gihita.Kubaho β icyiciro bigabanya ubukana bwa Hastelloy alloy, bigatuma yunvikana no kwangirika, ndetse ikanatera Hastelloy alloy Muri rusange kuvura ubushyuhe) hamwe nibikoresho bya Hastelloy byacitse mubidukikije.Kugeza ubu, uburyo busanzwe bwo gupima uburyo bwo kurwanya ruswa hagati ya Hastelloy alloys yagenwe nigihugu cyanjye ndetse n’ibindi bihugu ku isi ni uburyo busanzwe bwo guteka hydrochloric aside, kandi uburyo bwo gusuzuma nuburyo bwo kugabanya ibiro.Kubera ko Hastelloy ari umusemburo urwanya aside ya hydrochlorike, uburyo busanzwe bwo guteka aside hydrochloric ntabwo bwumva neza kugerageza kwangirika kwimiterere ya Hastelloy.Ibigo byubushakashatsi mu gihugu bifashisha uburyo bwa hydrochloric aside yo mu rwego rwo hejuru kugira ngo bige ku mavuta ya Hastelloy basanga kurwanya ruswa ya Hastelloy bitavanze gusa n’imiterere y’imiti gusa, ahubwo binaterwa n’uburyo bwo gutunganya amashyuza.Iyo uburyo bwo gutunganya amashyanyarazi bugenzuwe nabi, ntabwo ibinyampeke bya kristu ya Hastelloy bivanze gusa, ahubwo na σ icyiciro hamwe na Mo ndende bizagwa hagati yintete., imbibi zimbibi zingana nuburebure bwibisahani binini kandi isahani isanzwe ni hafi kabiri.
