Catalyst loading yog ib qho tseem ceeb ua ntej - cov txheej txheem ua haujlwm rau cov tshuaj tiv thaiv kab mob. Kev thauj khoom zoo ncaj qha cuam tshuam rau reactor txaj siab poob, kev faib dej thiab kev ua haujlwm catalytic, thiab txawm txiav txim siab ntev - lub sijhawm ua haujlwm ruaj khov ntawm tag nrho chav tsev. Txhawm rau zam kev thauj khoom tsis raug thiab tshem tawm cov kev phom sij ntawm kev nyab xeeb, tus qauv ua ntej- kev tshuaj xyuas kev thauj khoom yuav tsum tau ua tiav ua ntej kev thauj khoom tshiab ntawm cov catalysts.
Ua ntej, ua qhov kev soj ntsuam zoo ntawm cov catalysts lawv tus kheej.Xyuas kom tseeb tias tus qauv, specification thiab batch tooj ntawm catalysts phim cov ntaub ntawv tsim los tiv thaiv tsis ncaj ncees lawm los yog sib tov loading. Txheeb xyuas qhov ncaj ncees ntawm cov pob khoom catalyst rau kev puas tsuaj, noo noo, caking thiab pulverization. Tej yam uas deteriorated los yog unevenly loj catalysts vim ya raws yuav tsum tsis kam lees. Random qauv catalysts los soj ntsuam lawv cov tsos; pellets tsis muaj hmoov av ntau dhau yuav tsum tau ua. Sieving yog saws thaum tsim nyog los tshem tawm cov impurities kom tsis txhob muaj txaj thaiv thiab ntau lub siab poob thaum ua haujlwm. Tsis tas li ntawd, xyuas cov ntawv pov thawj ntawm kev soj ntsuam thiab cov ntawv xeem kom paub meej cov cim tseem ceeb suav nrog kev siv tshuab lub zog, kev ua haujlwm thiab qhov loj me me faib ua raws li cov txheej txheem tsim qauv.
Thib ob, ua kev soj ntsuam sab hauv ntawm lub reactor.Ua tib zoo ntxuav lub reactor sab hauv kom tshem tawm cov seem welding slag, xeb, khib nyiab thiab roj stains los ntawm kev tsim kho, kom ntseeg tau qhov chaw huv huv. Tshawb xyuas lub reactor sab hauv phab ntsa, txhawb nqa gratings, sieve phaj thiab ntim cov ntxaij vab tshaus. Paub meej tias cov gratings tsis muaj deformation, kev puas tsuaj thiab qhov khoob khoob, thiab cov ntxaij vab tshaus tau nruj nreem txuas yam tsis muaj qhov los yog tawg los tiv thaiv catalyst to thiab kua dej maldistribution. Lub caij no, xyuas qhov ntev ntawm sab hauv thiab cim cov kab ntawv ntawm lub txaj siab kom raug tswj xyuas qhov tob ntawm qhov chaw thau khoom. Kaw tag nrho cov khoom siv manholes tom qab kuaj xyuas kom tsis txhob muaj cov khoom txawv teb chaws thib ob poob rau hauv lub reactor.
Thaum kawg, tshuaj xyuas ua ntej- thauj khoom txhawb nqa thiab cov cuab yeej.Xyuas cov cuab yeej thauj khoom xws li funnels, hoses, thoob thiab cov cuab yeej tshuaj ntsuam xyuas kom ntseeg tau tias lawv huv, qhuav, tsis muaj paug thiab tsis muaj kab mob. Paub meej txog ntawm - qhov chaw ua pa, plua plav- pov thawj thiab tiv thaiv - cov chaw zoo li qub, cov khoom siv tua hluav taws ua tiav thiab ua haujlwm tau zoo, thiab thaj chaw ua haujlwm tau huv. Txheeb xyuas cov txheej txheem txheej txheem ntawm chav tsev: lub reactor tau depressurized, txias cia thiab tag nrho purged nrog tsim nyog gas detection, ua raws li qhov chaw kaw thiab loading kev ruaj ntseg. Kev thauj khoom catalyst tuaj yeem pib tsuas yog tom qab tag nrho cov khoom soj ntsuam dhau thiab cov ntaub ntawv tseem ceeb tau ua tiav.
