Dab tsi yog cov haujlwm ntawm cov kua ammonia loading caj npab

Niaj hnub no, tus editor yuav coj koj mus kawm txog cov kua ammonia crane raj. Cov kua ammonia yog rhuab mus rau 800-850 degree C thiab decomposed nyob rau hauv qhov kev txiav txim ntawm ib tug nickel raws catalyst kom tau ib tug hydrogen nitrogen sib tov roj uas muaj 75 feem pua ​​H2 thiab 25 feem pua ​​N2. Cov roj tau los ntawm txoj kev no yog cov roj tiv thaiv zoo. Cov kua ammonia feem ntau yog siv los tsim cov nitric acid, urea, thiab lwm yam tshuaj chiv, thiab tseem tuaj yeem siv los ua cov khoom siv raw rau tshuaj thiab tshuaj tua kab. Cov kua ammonia caj npab tseem hu ua "kua ammonia crane raj", thiab cov kua ammonia crane raj feem ntau yog siv rau kev thauj khoom thiab thauj cov tsheb thiab tsheb ciav hlau.
Peb yuav tsum xyuam xim rau kev nyab xeeb thaum thauj cov kua ammonia. Cov kua ammonia tuav cov kav dej yog siv thaum lub sij hawm kev thauj mus los ntawm cov kua ammonia, thiab kev teeb tsa ntawm cov kua ammonia tuav cov kav dej yuav tsum tau ua raws li cov kev cai rau kev thauj mus los ammonia. Rau nws txoj kev nyab xeeb siv, nws yuav tsum tau siv raws li kev xav tau ntawm kev siv. Hauv qab no yog cov lus qhia txog lub luag haujlwm tseem ceeb ntawm cov kua ammonia crane raj:
1. Kev nyab xeeb siab: Vim tias cov khoom sib khi ntawm cov kua ammonia crane yeeb nkab yog qhov tshwj xeeb, nws tuaj yeem ua tiav zoo sealing thaum lub sij hawm thauj khoom thiab tshem tawm yam tsis muaj qhov to, uas ib txwm ua rau cov dej thauj khoom thiab thauj khoom ntawm lub tsheb muaj kev nyab xeeb dua.
2. Kev ruaj ntseg zoo: Cov kua ammonia crane raj tuaj yeem thauj tau ntau yam xov xwm, txawm tias thaum thauj cov concentrated sulfuric acid, tsis muaj qhov siab.
3. Cov kua ammonia crane raj yog yooj yim rau kev khiav lag luam: nws tuaj yeem txhim kho kev ua haujlwm zoo. Raws li paub zoo, kev thauj khoom thiab tshem tawm ntawm petrochemical media yog qhov nyuaj heev. Txawm hais tias hoses pheej yig, lawv xav tau kev khiav hauj lwm phau ntawv thiab muaj teeb meem thaum lub sij hawm docking txheej txheem. Txawm li cas los xij, kev siv cov raj crane rau kev thauj khoom thiab kev thauj khoom yog kev ua haujlwm ib zaug thiab kev ua haujlwm yooj yim.
4. Kev ua haujlwm siab sealing: yuav tsis muaj qhov xau thaum lub sij hawm docking, uas tuaj yeem kov yeej ntau qhov tsis zoo ntawm cov hoses ib txwm muaj. Lub ntsiab lus tseem ceeb yog tias txoj hauv kev no tsis muaj qee qhov teeb meem tsis zoo thiab tsis yooj yim rau hauv kev thauj khoom thiab thauj khoom ib txwm muaj.
