Tus Saib Xyuas Kev Nyab Xeeb ntawm Methanol Loading and Unloading - Technological Breakthroughs and Applications of Special Loading Arms
Nrog rau kev loj hlob ntawm kev lag luam thee tshuaj lom neeg, methanol, ua ib qho tseem ceeb ntawm cov khoom siv tshuaj lom neeg, tau nyiam ntau yam rau kev nyab xeeb thiab kev ua haujlwm ntawm nws qhov chaw cia thiab kev thauj mus los. Methanol muaj cov yam ntxwv ntawm kev kub ntxhov, yooj yim crystallization ntawm qhov kub thiab txias, thiab vapor siab hloov pauv loj. Traditional loading thiab unloading cov cuab yeej yog ib qho nyuaj rau ua tau raws li nws hnyav ua hauj lwm yuav tsum tau. Qhov tshwm sim ntawm kev mob siab rau methanol Loading Arm muab kev daws teeb meem zoo tshaj plaws rau qhov teeb meem no.
Cov txheej txheem thev naus laus zis tseem ceeb ntawm methanol loading caj npab yog thawj zaug pom hauv cov khoom xaiv. Kev txiav txim siab me ntsis corrosiveness ntawm methanol rau cov pa roj carbon zoo tib yam thiab qhov yuav tsum tau ua kom huv si, cov khoom siv tseem ceeb siv 304 stainless hlau ua cov khoom tseem ceeb, thiab 316L stainless hlau raug xaiv nyob rau hauv qee qhov kev ua haujlwm hnyav los xyuas kom meej tias yuav tsis muaj cov khoom embrittlement lossis corrosion tsis ua haujlwm nyob rau hauv qhov kub ntawm -35℃txog 60 degree. Mainstream methanol loading caj npab feem ntau txais yuav tus tsim ntawm "hauv qab kaw loading thiab unloading + tsib rotary pob qij txha". Kev teeb tsa ntawm tsib pawg ntawm cov pob qij txha sib txuas tau zoo txhim kho txoj kev ywj pheej ntawm caj npab hauv qhov chaw peb sab, uas tuaj yeem hloov kho tau yooj yim rau cov kev xav tau ntawm cov khoom sib txawv ntawm cov tsheb thauj khoom thiab cov tso tsheb hlau luam, kom tsis txhob muaj kev pheej hmoo ntawm methanol volatilization thiab to hauv cov tsoos sab saum toj loading thiab unloading txoj kev.
Qhov kev hloov kho tshiab ntawm kev tiv thaiv kev nyab xeeb yog lwm qhov tseem ceeb ntawm methanol loading caj npab. Cov cuab yeej zoo li no feem ntau yog nruab nrog lub valve thaum muaj xwm txheej ceev. Thaum lub tsheb thauj khoom tsis raug tshem tawm, nws tuaj yeem txiav tawm qhov kev sib txuas thiab paub txog kev sib khi ntawm ob qho kawg hauv 0.3 vib nas this, tshem tawm tag nrho cov kev sib tsoo los ntawm cov raj xa dej. Nyob rau tib lub sijhawm, kev teeb tsa ntawm lub tswb ntsuas hluav taws xob hauv av ua kom ntseeg tau tias cov hluav taws xob zoo li qub tau tsim thaum lub sijhawm thauj khoom thiab tshem tawm cov txheej txheem raug xa tawm raws sijhawm, zam qhov kev pheej hmoo tawg los ntawm cov khoom zoo li qub. Nyob rau hauv qhov kev siv ntawm loj-scale thee chemical tej yaam num, ib chav tsev ntawm no hom kev thauj khoom caj npab tuaj yeem thauj khoom thiab tshem tawm ntau tshaj 200 tons hauv ib hnub, uas yog 40% ntau dua li cov cuab yeej siv ib txwm siv, thiab emissions ntawm volatile organic compounds (VOCs) tau raug txo los ntawm 92%, ua tiav ob qho kev txhim kho kev nyab xeeb thiab kev ua haujlwm.
Hauv kev teb rau tus kheej cov kev xav tau ntawm cov xwm txheej sib txawv, methanol loading caj npab kuj muaj peev xwm nthuav dav. Nyob rau hauv cov cheeb tsam txias heev nyob rau sab qaum teb, lub tsho tiv thaiv tshav kub tracing module tuaj yeem tswj qhov kub hauv lub raj xa dej los ntawm chav lossis hluav taws xob cua sov tracing los tiv thaiv methanol crystallization los ntawm thaiv cov raj xa dej; nyob rau hauv cov chaw ua si tshuaj lom neeg loj, kev sib koom ua ke ntawm cov roj theem rov qab module paub txog lub voj voog kaw ntawm tag nrho cov txheej txheem thauj khoom thiab tshem tawm cov txheej txheem, ntxiv kom txo qis ib puag ncig. Tsis tas li ntawd, daim ntawv thov ntawm lub ntse saib xyuas ua rau cov cuab yeej ua haujlwm thiab kev saib xyuas yooj yim dua. Tiag - lub sij hawm saib xyuas ntawm nruab nrab ntws tus nqi, siab, kub thiab lwm yam tsis los ntawm sensors, thiab cov ntaub ntawv yog synchronously xa mus rau lub chaw tswj. Thaum muaj qhov txawv txav tshwm sim, lub tswb tuaj yeem tshwm sim tam sim ntawd thiab cov txheej txheem kaw thaum muaj xwm txheej ceev tuaj yeem pib.
Nrog rau cov kev cai tiv thaiv ib puag ncig nruj zuj zus, qhov yuav tsum tau kaw thiab ntse methanol loading thiab unloading yog txhim kho tas li. Nyob rau hauv lub neej yav tom ntej, methanol loading caj npab yuav loj hlob mus rau lub teeb yuag, ntse thiab multi-kev koom ua ke. Los ntawm kev siv cov ntaub ntawv sib xyaw kom txo tau qhov hnyav ntawm cov cuab yeej siv, ua ke nrog cov cuab yeej digital ntxaib kom paub txog kev ua haujlwm ntawm cov chaw taws teeb thiab kev saib xyuas thiab kev saib xyuas kev kwv yees, nws yuav muab cov cuab yeej txhim khu kev qha ntau dua rau ntsuab thiab qis - carbon kev loj hlob ntawm cov thee tshuaj lom neeg kev lag luam.
