Air Separation Unit (ASU): txoj cai ua haujlwm thiab kev siv

 

Peb lub xeev-ntawm-the-art Air Separation Unit (ASU) harnesses lub zog ntawm cryogenic distillation kom zoo extract nitrogen los ntawm cov huab cua. Nov yog li cas peb cov txheej txheem tshiab ua haujlwm:
chilling:Peb pib los ntawm cua txias kom txias txias, nce mus rau -196 degree (-321 degree F), qhov chaw huab cua hloov pauv ntawm cov pa mus rau cov kua.
Liquefaction:Tom qab ntawd, cov cua supercooled undergoes liquefaction, teeb tsa theem rau kev sib cais.
Fractional Distillation:Nyob rau hauv lub towering distillation kem, cov cua liquefied yog methodically sib cais. Nitrogen, nrog rau nws qhov qis qis, yog ua tib zoo distilled los ntawm lwm yam atmospheric Cheebtsam.
Extraction:Cov nitrogen, tam sim no nyob rau hauv ib tug concentrated kua daim ntawv, sib sau ua ke nyob rau hauv qab ntawm kem. Los ntawm no, nws tau kos tawm thiab npaj rau ntau yam kev lag luam.
Siv cov ntsiab lus kub ntawm qhov sib txawv (-196 degree rau nitrogen thiab -183 degree rau oxygen), peb ASU tsis yog tsuas yog tsim rau nitrogen ntau lawm tab sis kuj tseem tuaj yeem cais lwm cov pa roj xws li oxygen thiab roj zoo, suav nrog argon, neon. , krypton, thiab xenon, thaum xav tau. Peb cov qib siab ASU tau tsim kho kom xa cov purity thiab kev ua tau zoo rau kev lag luam hauv kev xav tau cov pa roj zoo.

Dab tsi yog Air Separation Unit (ASU)

 

 

Siv cov ntsiab lus tshwj xeeb condensing ntawm huab cua cov khoom hauv qab atmospheric siab:

 

Nitrogen ntawm -320.4 degree F

Oxygen ntawm -297.3 degree F

Argon ntawm -302.5 degree F a

 

llows peb Cov Cuab Yeej Sib Ncaim Siab Tshaj Plaws (ASU) kom ua tau zoo cais cov pa roj carbon monoxide los ntawm liquefaction thiab distillation, peev ntawm lawv cov khoom sib txawv. Ntsiab ASU System Cheebtsam: Main Cua Compressor (MAC): Peb MAC plays lub luag hauj lwm tseem ceeb los ntawm compressing atmospheric huab cua rau 60-90 PSIG, uas ces nkag mus rau hauv lub ASU. Feem ntau siv los ntawm cov tshuab hluav taws xob muaj txiaj ntsig zoo, lub tshuab compressor no muaj ntau theem, feem ntau ntawm ob thiab peb, nrog rau cov cua txias hauv nruab nrab kom dissipate cov cua sov uas tsim los ntawm compression, yog li optimizing tag nrho cov txheej txheem rau ntxiv cua sib cais theem.

Streamlined Purity nrog Prepurification

Lub ASUs tshiab niaj hnub no tau nruab nrog Prepurifier Unit (PPU), ib qho tseem ceeb ntawm cov huab cua uas nkag mus rau hauv cov txheej txheem distillation yog tsis muaj impurities xws li ya raws, CO2, thiab hydrocarbons. Los ntawm kev ua haujlwm chillers kom txias huab cua thiab sophisticated condensate separators, PPU zoo tiv thaiv cov dej khov los ntawm kev cuam tshuam cov theem sib cais. Lub plawv ntawm PPU nyob rau hauv nws ob lub nkoj adsorptive, ntim nrog cov khoom siv desiccant thiab molecular sieve, ntes cov kab mob thiab tso cai rau huab cua huv mus rau kev vam meej. Nrog rau lub txaj hloov pauv tsis siv neeg, ASU tswj lub voj voog ua kom huv si tas li, ua rau cov dej ntws tawm ze li ntawm cov dej noo thiab CO2.
Rau cov chaw nyiam cov kev coj noj coj ua, ASUs laus dua tuaj yeem xa rov qab cov khoom siv hluav taws xob hloov pauv, uas yog qhov ua tau zoo ntawm kev ua kom tsis muaj dej noo thiab CO2 ntawm cov phaj tshwj xeeb cryogenic. Cov txheej txheem cyclic, tswj los ntawm precision li qub, ua kom cov khoom tsis tu ncua ntawm huv huv, cua txias rau hauv lub tshuab distillation.
Txawm hais tias lawv qhov sib txawv, ob lub tshuab ua haujlwm tau zoo, nrog rau cov khoom siv hluav taws xob thim rov qab tau lees paub rau lawv cov nqi ua haujlwm tau zoo thiab cov txiaj ntsig kev nqis peev pib.
