Hastelloy B: Ruswa - Vanguard irwanya ibidukikije bigabanya ruswa
Dec 23, 2025
Nka nikel - molybdenum - ruswa ruswa - irwanya ruswa, Hastelloy B yabaye ibikoresho byingenzi mu nganda nk’ubuhanga bw’imiti na peteroli yo gukoresha ibidukikije byangirika cyane, bitewe n’imikorere idasanzwe mu bitangazamakuru byangiza aside. Ibyiza byayo biragaragara cyane mugihe ugereranije nibisanzwe.
Mu bidukikije byongera aside nka hydrochloric aside na acide sulfurike, aside Hastelloy B irwanya ruswa ntakintu kiri munsi y "igipimo." Bitandukanye na 316L ibyuma bitagira umwanda, bibabazwa no kwangirika byihuse hagati ya - acide hydrochloric aside, Hastelloy B irashobora gukora neza muri acide hydrochloric ku bushyuhe buri munsi ya dogere 80. Iyo ugereranije na nikel - chromium alloys (urugero, Inconel 600) yibanda ku kurwanya okiside, ibiyigize byinshi bya molybdenum (26% -30%) bigira urwego ruhamye rwa pasiporo, bikarwanya neza isuri ya hydrogène kandi bigakemura ikibazo cyo kwangirika kwa firime muri acide yangiza.
Hastelloy B nayo nziza cyane mubidukikije bigabanya imbaraga za chloride ion nyinshi. Irwanya gutobora, kwangirika kwangirika, no gucika intege. Ugereranije na titanium alloys, ikunze kwibasirwa na hydrogène muri aside hydrochloric aside, cyangwa Monel alloys, idafite imbaraga zo kurwanya ruswa ihagije mu bushyuhe bwo hejuru - aside hydrochloric aside, Hastelloy B itanga igihe kirekire -. Ndetse no mu bushyuhe bwo hejuru - (200 - 300 dogere) acide reductive cyangwa sulfure - irimo itangazamakuru - nkibihe bibi byamavuta ya hydrodesulfurizasi ya peteroli - ikomeza ibintu byiza bya mashini hamwe no kurwanya ruswa, irusha ruswa ruswa - ibyuma byose hamwe na nikel.
Ibyiza byayo bitandukanye nandi manota ya Hastelloy biragaragara: muri acide hydrochloric isukuye neza, irerekana ruswa irwanya ruswa kurusha serivise ya Hastelloy C (iruta mubitangazamakuru bivanze) ku giciro gito; murwego rwo hejuru - acide hydrochloric aside, irwanya ruswa iruta iy'uruhererekane rwa Hastelloy G, yibanda ku kurwanya aside sulfurike.
Kuva muri laboratoire kugera ahakorerwa inganda, Hastelloy B, hamwe nintego zayo zo kwangirika - inyungu zidashobora kwihanganira, igaragara nk "inzitizi yo gukingira" ingenzi mubidukikije byangirika.
