Yuav ua li cas ntxuav lub hluav taws xob hloov hluav taws xob hloov roj rauv?
Thaum siv, cov roj kub yuav coke thiab khaws cov pa roj carbon monoxide, uas tuaj yeem tsim cov txheej txheem rwb thaiv tsev thiab txo cov cua sov ua haujlwm. Yancheng Guangzhi qhia koj yuav ua li cas ntxiv additives xws li alkalis, organic solvents thiab surfactants, complexing agents, oxidants, corrosion inhibitors, adsorbents, anti settling agents, thiab lwm yam, thiab ces ntxuav lub system los ntawm cua sov thiab mechanical txhuam. Decoking yog ua tiav los ntawm solubilization, ntub dej, adsorption, emulsification, thiab dispersion ntawm surfactants.
Muaj ob kauj ruam rau alkaline ntxuav thiab kua qaub ntxuav ntawm hluav taws xob cua sov cua sov hloov cov roj rauv: tso tawm cov roj hloov hluav taws xob → chav tshuab cov roj → alkaline detergent → dej ntxuav → kua qaub ntxuav → passivation → tiav. Lub hauv paus ntsiab lus: Alkaline dej-raws li cov neeg ua haujlwm tu muaj kev kho mob zoo ntawm cov roj nruab nrab kub cov pa roj carbon deposits, tab sis tom qab kev kho mob, tseem muaj ib tug ntom graphitized high-temperature carbon deposit txheej nyob rau hauv lub puab phab ntsa ntawm cov qauv, uas yuav tsum tau muab tshem tawm ntxiv los ntawm acid. kev ntxuav kom tsis txhob muaj cov pa roj carbon seem uas cuam tshuam rau qhov zoo thiab cov khoom siv hluav taws xob hloov hluav taws xob ntawm cov roj hloov hluav taws xob. Pipeline carbon deposition txais ob kauj ruam: alkali tu thiab kua qaub tu, uas muaj qhov zoo ntawm kev tu tus nqi siab, tsis tshua muaj kev tu kub, thiab tus nqi qis.
Organic ntxuav cov txheej txheem rau cov khoom siv hluav taws xob hloov hluav taws xob: Ntxiv cov khoom siv ntxiv rau cov roj hloov hluav taws xob tuaj yeem tev tawm cov roj carbon deposits, thiab tom qab ntawd tshem tawm cov roj seem los ntawm kev qhia meej thiab pom. Lub hauv paus ntsiab lus: Lub tswv yim tam sim no tau txais ib txoj hauv kev zoo sib xws los ntxuav cov roj coking lossis degrade coking roj nplai kom tiv thaiv nws qhov kev puas tsuaj. Txoj kev no yog kev ruaj ntseg rau kev tu. Qhov kev tsim kho tam sim no tuaj yeem yaj hauv cov roj hloov hluav taws xob ntawm qhov kub siab tshaj 260 degree yam tsis muaj kev cuam tshuam rau nws lub cev, thiab nws qhov ntau npaum li cas tuaj yeem tshaj 5 feem pua ​​​​ntawm cov roj hloov hluav taws xob. Thaum siv, lub tshuab hluav taws xob hloov hluav taws xob thiab cov kav dej tsis tas yuav tsum tau txias, uas tsis cuam tshuam rau kev tsim khoom.
Chaw tsim tshuaj paus ntawm hluav taws xob thermal roj rauv
Dissolution tu txheej txheem: tawm ntawm tshav kub hloov roj → chav tshuab ntawm cov roj residual → organic solvent ntxuav kua → passivation. Lub hauv paus ntsiab lus yog tias coke nplai yog qhov sib xyaw ua ke feem ntau yog tsim los ntawm cov organic teeb meem, thiab nws qhov adhesion rau cov hlau nto yog feem ntau los ntawm lub cev adsorption. Lub tshav kub hloov hluav taws xob roj rhaub ntawm Yancheng Guangzhi siv lub tshuab ntxuav tais diav kom yaj cov tar hauv cov kuab tshuaj organic, uas tau raug tshem tawm nrog kev sib cais ntawm cov organic teeb meem. Kev tu lub peev xwm ntawm cov tshuaj detergent no zoo heev.
Cov txheej txheem kev tu vaj tse rau cov cua kub hloov cov roj tso cua sov: tso cov roj hloov hluav taws xob → siv cov pa los cheb cov roj seem → siv cov tshuaj ntxuav kom huv thiab huv. Lub hauv paus ntsiab lus: Composite tu cov neeg ua haujlwm feem ntau yog tsim los ntawm ntau cov surfactants adsorbed ntawm oily nto nyob rau hauv lub synergistic nyhuv ntawm kev pab tu, ua rau nws ntub thiab nthuav. Tom qab ntawd, tus neeg sawv cev ntxuav nkag mus rau hauv qhov khoob ntawm cov av oily, ua rau cov roj maj mam dov mus rau hauv micelles thiab tsis tu ncua emulsify nyob rau hauv qhov kev txiav txim ntawm cov tshuaj ntxuav vaj huam sib luag. Dispersed emulsified roj stains yuav raug cais tawm ntawm tshav kub hloov chaw los ntawm kev tu lub voj voog tas li los ntawm lub twj tso kua mis. Tus neeg sawv cev no tsis tsuas yog ua kom zoo thiab tawg cov pa roj carbon deposits, tab sis kuj zoo dissolves organic hydrocarbons. Cov txheej txheem yog yooj yim thiab yeej tsis muaj corrosion rau lub tshav kub hloov roj rhaub, tab sis nws yuav tsum tau ntxuav thaum nres tsheb.
