Kev Tiv Thaiv Corrosion cuam tshuam li cas rau Sulfuric Acid Plant Equipment Service Life?
Hauv kev tsim cov sulfuric acid, cov khoom siv corrosion yog ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm cov nroj tsuag, kev tu ntau zaus, thiab cov nqi tsim khoom. Cheebtsam xws li sulfur burners, acid circulation tanks, absorption towers, heat exchangers, pipelines, thiab twj tso kua mis tsis tu ncua raug rau sulfuric acid, sulfur dioxide, sulfur trioxide, thiab siab - kub txheej txheem gases. Yog tias tsis muaj kev tiv thaiv corrosion tsim nyog, cov hlau saum npoo yuav ua rau nyias nyias, tawg, tawg, lossis tsis xav tau kaw.
Rau cov neeg ua haujlwm cog tshuaj, kev tswj xyuas corrosion tsis yog tsuas yog cuam tshuam nrog cov cuab yeej siv tau ntev, tab sis kuj tseem txuas nrog cov txheej txheem kev nyab xeeb thiab kev ua haujlwm ntau lawm. Xaiv cov ntaub ntawv tsim nyog, siv cov txheej txheem tiv thaiv, tswj kev ua haujlwm, thiab tsim cov khoom siv raws li cov yam ntxwv ntawm corrosion yog qhov tsim nyog yuav tsum tau ua thaum tsim cov sulfuric acid ntau lawm.
Asia Chemical Engineering Co., Ltdmuab engineering daws teeb meem rauSulfuric Acid tsob nrojtej yaam num, tsom rau cov khoom tsim, xaiv cov khoom siv, txoj kev tiv thaiv corrosion, thiab cov txheej txheem optimization los pab cov neeg siv khoom tsim kom ruaj khov tshuab tsim nyog rau kev ua haujlwm ntev -.
Vim li cas Corrosion yog ib qho kev sib tw loj hauv Sulfuric Acid Production Equipment?
Sulfuric acid muaj cov tshuaj lom neeg muaj zog, tshwj xeeb tshaj yog nyob rau hauv siab -kub los yog thaum ua ke nrog cov dej noo. Thaum lub sij hawm tsim khoom, ntau seem ntawm cov nroj tsuag ntsib qhov sib txawv corrosion ib puag ncig.
Piv txwv li, nyob rau hauv qhuav thiab nqus seem, sulfuric acid pos huab thiab concentrated acid ncig tuaj yeem tua cov pa roj carbon steel yog tias cov khoom xaiv tsis tsim nyog. Hauv cov chaw ua roj, sulfur dioxide thiab sulfur trioxide tuaj yeem hnov mob nrog noo noo los tsim cov acidic tebchaw uas ua kom corrosion.
Cov yam tseem ceeb ntawm corrosion muaj xws li:
Sulfuric acid corrosion tus cwj pwm hloov nyob ntawm qhov concentration. Cov kua qaub diluted yuav ua rau muaj kev xeb loj heev ntawm cov hlau vim tias dej ua rau muaj kev ua haujlwm ionic thiab tshuaj lom neeg. Concentrated sulfuric acid tuaj yeem tsim kev tiv thaiv oxide txheej ntawm qee cov hlau, tab sis qhov kev tiv thaiv no yuav txo qis ntawm qhov kub siab. Yog li, cov khoom siv khoom siv yuav tsum raug xaiv raws li qhov tseeb acid concentration thiab ua haujlwm kub.
Kub ncaj qha cuam tshuam cov tshuaj tiv thaiv corrosion ceev. Cov khoom siv xws li cov khoom siv hluav taws xob sib hloov thiab cov kua qaub tuaj yeem ua haujlwm nyob rau hauv qhov kub siab, ua rau cov tshuaj tiv thaiv kab mob ntawm cov kua qaub thiab hlau. Cov khoom uas ua tau zoo nyob rau hauv chav tsev kub tej zaum yuav tsis muaj kev tiv thaiv txaus nyob rau hauv tas li siab - kub ua hauj lwm.
Kev sib kis dej yog ib qho tseem ceeb ua rau muaj teeb meem corrosion. Thaum lub sij hawm sulfur burning thiab gas conversion txheej txheem, noo noo tuaj yeem tsim sulfuric acid pos huab, uas tuaj yeem ua rau cov khoom siv puas tsuaj thiab cov khoom siv sab hauv. Cov tshuab ziab khaub ncaws kom zoo thiab cov txheej txheem tswj kom zoo pab txo qis kev pheej hmoo corrosion.
