Daim ntawv thov ntawm Titanium hauv kev ua kom zoo nkauj thiab tshuaj lom neeg: kev xaiv zoo rau corrosion tsis kam

Ib cov khoom siv txhim khu kev qha rau kev cuam tshuam nrog dej corrosion

Kev kho dej yog qhov tseem ceeb hauv koj lub chaw ua kom zoo. Ib tug xov tooj ntawm cov tuam txhab yog nyob ze rau cov khoom siv tshiab dej tab sis kev ua dej haus yog tsim nyog rau kev tiv thaiv thiab kev sib tw yaig hauv cov khoom lag luam ib txwm muaj carbon hlau. Tab sis, cov kev cai ib puag ncig yuav tsum tau hais tias kev kho dua tshiab rov qab ua dua cov dej khib nyiab, uas feem ntau yog xeb. Txhawm rau txo cov dej khib nyiab thiab tshem tawm cov khoom siv puas tsuaj thiab kev txij nkawm cov nqi ua los ntawm kev corrosion, nws yog ib qho tseem ceeb kom xaiv corrosion resistant cov ntaub ntawv. Titanium qhov zoo tshaj plaws corrosive tsis kam rau cov dej khov (piv txwv li dej hiav txwv, cov kev xaiv loj me thiab dej ntws tawm ntawm cov dej no. Piv txwv li, hauv qee lub kaw lus koom nrog dej ncig thiab cov khoom siv dej khib nyiab tuaj yeem ua haujlwm rau cov khoom siv hauv lub neej thiab kev txo cov kab mob ib puag ncig xws li kev xau los ntawm kev xeb.

Qhov xwm txheej ruaj khov tiv thaiv sulfide corrosion

Cov roj uas muaj roj muaj ntau ntawm cov leej txiv leej ntoo, feem ntau yog nyob rau hauv daim ntawv ntawm cov tebchaw, nrog ib qho me me yog hydrogen sulfide (h ₂ s). Nyob rau hauv cov roj av, cov leej faj yog qhov nyuaj rau tshem tawm kiag li. Tom qab nkag mus rau lub chaw tsim hluav taws xob, qee cov sulfides hauv cov roj crude yuav hloov mus rau h ₂ s nyob rau hauv kev kub kub thiab kub siab. Nyob rau tib lub sijhawm, H ₂ s yuav tsim los ntawm hydrogenation thiab lwm yam kev sib raug zoo catalytic. Sulfidation thiab pitting corrosion nyob rau hauv high-}} cov ntaub ntawv daws teeb meem ntawm cov sulrosion, muaj ntau yam thiab muaj kev cuam tshuam nrog corrosion hauv cov txheej txheem ua kom zoo dua qub. Titanium muaj qee yam tsis kam mus rau siab siab rau high- kub sulfurization thiab pitting corrosion, nrog rau kev ntxhov siab corrosion ntawm sulfides. Nyob rau hauv tus txheej txheem ntawm roj av ua kom zoo nkauj, ntsev thiab leej faj hauv cov roj crude tuaj yeem ua rau cov hlau loj heev rau cov khoom siv tsis muaj roj hlau. Yog li ntawd, titanium yog xav tau los ua cov khoom tseem ceeb xws li kev hloov cua sov, distillation yees, thiab reactors rau roj av ua kom zoo nkauj. Titanium kav yog feem ntau siv rau anti- corrosion kho nyob rau hauv lub txias zog ntawm cov roj av distillation ntauwd dhau. Thaum siv cov roj av uas tsis sib haum rau qhov siab- kub fricalsation 121℃yuav hloov pauv ntawm cov sulfide hydrogen hydrogen sulfide. Cov txiaj ntsig kev sim uas cuam tshuam tau qhia tau tias kev siv titanium hauv cov hws thiab kev hloov pauv kub tuaj yeem yuav luag tsis quav ntsej nws corrosiveness. Titanium hlab tau ua ntej thov rau sab saum toj condenser ntawm cov roj av uas distillation yees xyoo 1960 thiab tau siv dav txij li thaum ntawd. Kev sib xyaw ntawm cov raj titanium bundles thiab cov raj nplooj tau raug siv tau ntau xyoo hauv Tebchaws Meskas thiab Tebchaws Askiv ua rau muaj kev pabcuam lub neej ntawm kev ua kom zoo dua qub.

Corrosion tsis kam nyob rau hauv hydrogenation desulfurization thiab hydrogen desulfurization

Nyob rau hauv cov txheej txheem ntawm hydrogenation desulfurization nyob rau hauv kev kho kom zoo nkauj, qhov ntsuas kub yuav tsum tau tsa rau cov khoom siv 343 dhau los tawm ntawm cov khoom siv los ntawm kev txias thiab sib cais. Thaum lub sijhawm cov txheej txheem no, cov cuab yeej yuav fim cov tshuaj corrosion los ntawm ntau cov tshuaj corrosive xws li hydrogen sulfide, hydrogen chloride, thiab ammonia. Titanium hlab yuav ua tau zoo tiv thaiv cov yaig ntawm cov tshuaj, thiab yog li cov khoom siv txias hauv hydrogen ntau ntxiv, siv tau hloov cov hlau. Getty roj hauv Tebchaws Meskas ntau yam siv titanium hlab li kub hloov pauv thaum xyoo 1972, thiab lawv cov kev ua kom zoo nkauj tau ua rau pom tseeb yam tsis muaj teeb meem.

Corrosion Resistant cov cuab yeej hauv acidic roj kho

Acidic gases must be discharged in refining and chemical production.An aqueous solution of ethanolamine is the most frequently employed adsorbent type, primarily comprising monoethanolamine and diethanolamine, which are adsorbents for hydrogen sulfide and carbon dioxide, respectively. Tab sis cov neeg rov ua dua yog ntau ntxiv rau kev yaig ntau dua lwm qhov txij li Rebiler yog cov khoom siv cua sov. Vim tias qhov zoo heev corrosion tsis kam ntawm titanium, titanium raj nrog monoethanolamine reboiler yog kev ua haujlwm zoo heev, uas tuaj yeem ua tiav txuag lub neej ua haujlwm thiab stably.

Cov tseem ceeb los tiv thaiv - corrosion ntsuas nyob rau hauv extraction thiab txheej txheem rov ua dua tshiab

Nyob rau hauv extraction technology ntawm kev ua kom zoo nkauj thiab tshuaj lom neeg, txoj kev rov ua haujlwm tuaj yeem ua rau muaj kev mob corrosion. Feem ntau ntawm cov txheej txheem niaj tam sim no siv cov kuab tshuaj thiab distillation rau kev sib cais, ua raws li cov kev sib cais hauv ntauwd. Qee qhov kev rho tawm lawv tus kheej tsis corrode, tab sis thaum lub sij hawm ua dua tshiab, muaj ntau cov kua qaub yog tsim tawm, uas muaj cov nyhuv muaj zog ntawm ib puag ncig. Ib qho me me ntawm cov khoom sib txuas lus xws li hydrogen sulfide tseem tuaj yeem muaj qee yam kev kho mob ntawm ib puag ncig. Lub hom phiaj corrosion yog txias yees yees thiab khoom siv rov ua dua tshiab. Lub isti - corrosion kev ua haujlwm ntawm titanium tuaj yeem txo qis cov khoom siv xeb ntawm kev rho tawm. Yog tias cov lag luam tsis tuaj yeem hloov kho cov khoom siv rau corrosion yam, nws kuj tuaj yeem hloov lub corroded corroded qhov chaw los yog coating lub sab hauv ntawm cov khoom siv nrog titanium alloy.

Corrosion tiv thaiv ntawm catalytic cracking chav tsev

Kev lag luam kho kom zoo nkauj thiab tshuaj lom neeg yog qhov txuas tseem ceeb hauv kev sib txuas txhua hnub thiab cov txheej txheem tawg uas tsim cov khoom xeb corrosive. Muaj ntau tus ntawm cov txiv neej hauv CR

UDE roj, uas tsim ntau npaum li cas ntawm hydrogen sulfide thiab nitrogen sib xyaw thaum lub sij hawm catalysis thiab ua tiav cov txheej txheem. Cov tebchaw no tuaj yeem muaj cov txiaj ntsig corrosive raws li kev ua dej. Qhov kub thiab txias thaum lub sijhawm catalysis thiab cracking cov txheej txheem yog kwv yees li ntawm 40℃c. Yog tias "hydrogen cracking" tshwm sim ntawm cov hlab catalytic. Yog li ntawd, ntxiv Titanium rau cov catalytic crushing chav muaj zoo corrosion tsis kam. Tebchaws Asmeskas yog thawj zaug siv titanium hauv kev kho kom zoo nkauj. Cov khoom siv hluav taws kub hauv Tebchaws Gedi tau siv cov tub rog catalort, uas hloov chaw ua ke nrog cov txiaj ntsig catalanium, thiab kev hloov pauv ntawm cov txiaj ntsig kev sib tsoo nrog cov txiaj ntsig zoo thiab tsis muaj kev ua kom haum rau cov txiaj ntsig zoo thiab tsis muaj kev cuam tshuam zoo.
