Nkag siab Acid Dew Point Corrosion: Yuav Ua Li Cas Cov Chaw Ua Lag Luam Ua Tau Raws Li Qhov Kev Sib Tw?

Acid dew point yog hais txog qhov kub thiab txias uas cov tshuaj acidic muaj nyob hauv cov huab cua mus txog lub xeev saturated thiab condense rau hauv cov kua qaub. Feem ntau hais lus, nws yog hais txog qhov kub ntawm cov kua qaub nag condenses nyob rau hauv huab cua nyob rau hauv atmospheric siab. Txawm li cas los xij, qhov xwm txheej huab cua txawv txawv no tsis yog huab cua hloov pauv xwb, tab sis muaj kev cuam tshuam zoo rau kev tsim khoom lag luam.

Yog li, yog dab tsiacid dew point corrosion? Cov yam ntxwv ntawm acid dew point corrosion muaj ntau yam xws li huab cua kub, av noo, thiab acid cov ntsiab lus. Nyob rau hauv cov xwm txheej no, acid dew point yuav inevitably tshwm sim. Tshwj xeeb tshaj yog nyob rau hauv qee qhov chaw ua lag luam, cov kua qaub dew point tuaj yeem yooj yim ntxiv rau hauv kev ncaj ncees ntawm kev xa khoom, valve thiab pipeline interfaces, chimneys, condensers thiab lwm yam khoom siv. Rau complex industrial ntau lawm ib puag ncig, nws yog ib qhov nyuaj rau kom daws tau qhov teeb meem ntawmacid dew point corrosion, thiab nws tsuas tuaj yeem nyob thiab zam dhau ntawm qee yam khoom siv siab heev.

Tus yuam sij los daws qhov teeb meem no yog siv cov kua qaub dew point ntsuas kub los saib xyuas cov kev hloov pauv ntawm cov kua qaub dew point hauv lub sijhawm, nrog rau cov kua qaub dew point nyob rau hauv qhov chaw tsim khoom. Los ntawm kev txheeb xyuas qhov tseeb ntawm qhov ntsuas, qhov ua rau ntawmacid dew point corrosiontuaj yeem nyob sai sai, thiab kev ntsuas tsim nyog tuaj yeem xaiv los daws nws. Tsis tas li ntawd, cov kua qaub dew point ntsuas kub ntsuas tau siv dav hauv kev tsim khoom thiab lwm yam kev lag luam, txhim kho cov teeb meem acid dew point hauv kev lag luam, txo qhov cuam tshuam ntawm cov kua qaub dew point ntawm cov khoom siv, thiab ua kom muaj kev lag luam zoo.
