CovNMP hnyav rov qab systemsuav nrog ntau yam tseem ceeb, txhua tus ua haujlwm tshwj xeeb hauv cov txheej txheem rov qab los. Cov khoom siv no ua haujlwm ua ke kom ua tau zoo tshem tawm NMP cov kuab tshuaj los ntawm cov txheej txheem ntws, rov ua dua rov siv dua, thiab xyuas kom ua raws li cov cai ntawm ib puag ncig. Nov yog cov lus piav qhia ntxaws txog cov khoom thiab lawv lub luag haujlwm:
Pub Tank lossis Tuav Vessel:
Lub tank pub los yog tuav lub nkoj yog qhov uas cov kab mob NMP hnyav tau pib sau los ntawm ntau cov txheej txheem ntws. Cov khoom no ua haujlwm raws li lub thawv ntim khoom ib ntus rau cov kuab tshuaj ua ntej nws nkag mus rau cov txheej txheem rov qab.
Distillation Kem:
Cov kab distillation yog lub hauv paus tseem ceeb ntawm cov kuab tshuaj rov qab uas qhov kev sib cais ntawm NMP hnyav los ntawm cov khoom paug tshwm sim. Lub kem siv lub hauv paus ntsiab lus ntawm fractional distillation, qhov sib tov yog rhuab mus rau vaporize cov kuab tshuaj, thiab ces cov vapor yog condensed rov qab mus rau hauv cov kua daim ntawv, cais nws los ntawm lwm yam khoom raws li qhov sib txawv ntawm boiling ntsiab lus.
Reboiler:
Lub reboiler yog lub tshav kub exchanger nyob rau hauv lub hauv paus ntawm lub distillation kem. Nws lub luag haujlwm tseem ceeb yog muab cua sov rau hauv qab ntawm kem, vaporizing cov kua pub thiab ua kom yooj yim rau kev sib cais ntawm NMP hnyav los ntawm cov kab mob.
Condenser:
Lub condenser yog lwm lub tshav kub exchanger nyob rau sab saum toj ntawm kab distillation. Nws lub luag haujlwm yog kom txias thiab condense NMP vapor rov qab mus rau hauv cov kua dej tom qab nws tau muab cais tawm ntawm cov kab mob. Cov condensed NMP hnyav tau sau thiab khaws cia rau rov siv dua.
Rov qab Solvent Separator:
Cov kuab tshuaj rov qab yog ib qho khoom siv uas pab cais cov kab mob seem ntawm cov kab mob los ntawm NMP cov kuab tshuaj zoo. Nws ua kom ntseeg tau tias cov kuab tshuaj siv tau ua tau raws li cov kev qhia purity ua ntej muab rov qab rau hauv cov txheej txheem.
Thaum tshav kub kub Exchangers:
Thaum tshav kub kub exchangers yog siv thoob plaws hauv lub cev hnyav rov qab los hloov cov cua sov kom zoo ntawm cov txheej txheem sib txawv. Lawv pab txhim kho kev siv hluav taws xob zoo los ntawm kev rov ua kom sov los ntawm cov txheej txheem ntws tawm thiab hloov mus rau cov kwj tuaj, txo cov kev siv hluav taws xob tag nrho.
Pumps thiab Valves:
Cov twj tso kua mis thiab cov li qub yog cov khoom siv tseem ceeb siv los tswj cov dej ntws ntawm cov kuab tshuaj thiab lwm cov kua dej hauv cov txheej txheem rov qab. Lawv ua kom muaj kev sib raug zoo ntawm cov kuab tshuaj los ntawm ntau theem ntawm cov txheej txheem rov qab thiab tso cai rau kev hloov pauv hauv cov nqi ntws raws li xav tau.
Instrumentation thiab Control System:
Kev ntsuas thiab tswj cov tshuab saib xyuas thiab tswj ntau yam tsis xws li qhov kub thiab txias, siab, ntws tus nqi, thiab hnyav hnyav thoob plaws hauv cov txheej txheem rov qab. Lawv muab cov ntaub ntawv ntawm lub sijhawm tiag tiag thiab pab cov neeg ua haujlwm kho cov haujlwm ua haujlwm kom ua kom zoo dua qub thiab ua kom muaj kev nyab xeeb.
Safety Systems:
Cov txheej txheem kev nyab xeeb tau muab tso rau hauv cov kuab tshuaj rov qab los tiv thaiv thiab txo cov kev phom sij, xws li overpressure, overheating, lossis cov khoom ua haujlwm tsis zoo. Cov tshuab no suav nrog lub siab nyem li qub, ntsuas qhov ntsuas kub, lub tshuab kaw thaum muaj xwm txheej ceev, thiab lub tswb kom ua haujlwm nyab xeeb.
Environmental Controls:
Kev tswj ib puag ncig yog siv los ua kom ua raws li cov qauv kev cai rau kev tso pa tawm thiab pov tseg pov tseg. Qhov no yuav suav nrog cov tshuaj txhuam hniav lossis cov lim dej kom tshem tawm cov kab mob uas tseem tshuav los ntawm cov pa roj ua ntej lawv tso rau hauv qhov chaw.
Kev Saib Xyuas thiab Kev Tshaj Tawm Systems:
Kev saib xyuas thiab kev tshaj tawm cov tshuab muab cov neeg ua haujlwm nrog cov ntaub ntawv hauv lub sijhawm ntawm kev ua haujlwm ntawm lub cev, suav nrog cov kuab tshuaj rov qab, qib purity, kev siv hluav taws xob, thiab ua raws li cov cai ntawm ib puag ncig. Cov ntaub ntawv no yog siv los ua kom zoo dua qhov kev ua haujlwm thiab taug qab kev ua haujlwm dhau sijhawm.
