Titanium Thiab Titanium Alloys: Cov ntaub ntawv tseem ceeb rau kev siv hauv Kev Lag Luam Kev Lag Luam

Roj, "ntshav" ntawm kev lag luam niaj hnub, coj cov kev xav tau siab ntawm cov khoom siv kho kom zoo thaum txhawb kev loj hlob ntawm kev sib raug zoo. Nyob rau hauv cov txheej txheem roj refining, vim muaj ntau haiv neeg thiab corrosiveness ntawm raw cov ntaub ntawv, kev xaiv ntawm cov cuab yeej ua ib qho tseem ceeb heev. Titanium thiab titanium alloys, vim tias lawv zoo heev corrosion kuj, maj mam tuav txoj haujlwm tseem ceeb hauv kev lag luam roj refining.
Cov keeb kwm ntawm titanium hauv kev lag luam chemical refining tuaj yeem taug qab mus rau lub caij txias thaum ntxov. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov ntawm titanium thiab nws cov alloys tau nthuav dav thiab tam sim no tau siv dav hauv cov cuab yeej tseem ceeb xws li hloov hluav taws xob, condensation thiab txias. Cov khoom ntawm cov khoom no raug rau qhov kub thiab txias, siab siab thiab corrosive media thaum lub sij hawm refining txheej txheem, thiab cov khoom zoo heev ntawm titanium thiab titanium alloys yog qhov kev xaiv zoo tshaj plaws los ua kom tau raws li cov kev cov nyom no.

Kev lag luam txawv teb chaws hauv kev siv cov khoom siv titanium tau ze li 40 xyoo ntawm keeb kwm. Nyiv, vim tsis muaj cov peev txheej ntawm cov roj, feem ntau yog cia siab rau cov roj ntsha uas muaj sulfur crude, yog li nyob rau hauv kev tiv thaiv corrosion muaj kev nplua nuj kev paub. Lawv siv cov ntaub ntawv titanium alloy los daws cov teeb meem H2S-HCL-H2O ib puag ncig corrosion, thiab ua tiav cov txiaj ntsig zoo kawg. Cov teb chaws Europe thiab Tebchaws Meskas kuj tau pib siv cov titanium kub exchangers hauv cov roj refineries thaum ntxov li 1960s kom tau raws li cov kev cov nyom ntawm ntau yam corrosive media.
Hauv Suav teb, txawm hais tias kev lag luam petrochemical tau ua haujlwm tseem ceeb, tab sis cov khoom siv titanium siv hauv kev lag luam refining tseem me me. Txawm li cas los xij, nrog txoj kev loj hlob sai ntawm kev lag luam thiab kev loj hlob sai ntawm kev thov rau cov roj, tshwj xeeb tshaj yog Middle East siab sulfur crude roj ntshuam nce xyoo los ntawm lub xyoo, Tuam Tshoj txoj kev hloov pauv thiab kev kho dua tshiab ntawm cov khoom siv roj refining muab rau cov kev xav tau ntau dua. Titanium thiab titanium alloys yuav dhau los ua cov khoom tseem ceeb thiab tseem ceeb hauv kev lag luam roj refining yav tom ntej vim lawv zoo heev corrosion kuj.
