Cryogenic ASU Rau Kev Lag Luam Tshuaj

Hauv cov nroj tsuag tshuaj, kev ntseeg siab ntawm kev lag luam gases ncaj qha cuam tshuam rau tag nrho cov kev ua tau zoo. Lub cryogenic ASU rau kev lag luam tshuaj tsis yog cov txheej txheem pob - nws yuav tsum tau ua ke nrog cov kev xav tau qis qis, kev txwv purity, thiab cov sijhawm ua haujlwm tas mus li. Hauv qab no yog cov ntaub ntawv pov thawj kev ua haujlwm thiab kev xaiv cov logics raws li kev ua haujlwm tiag tiag.

Txoj Cai Txheej Txheem

Cua yog compressed, ua ntej-cooled, thiab purified los ntawm molecular sieves ua ntej nkag mus rau hauv lub thawv txias. Tom qab txias rau qhov kub thiab txias (-170℃rau -193 degree) nyob rau hauv lub ntsiab tshav kub exchanger, kev sib cais tshwm sim nyob rau hauv lub distillation kem raws li boiling point sib txawv (O₂: -183 degree, N₂: -196 degree). Lub cryogenic ASU rau kev lag luam chemical feem ntau xa cov pa oxygen ntau dua lossis sib npaug rau 99.6% purity thiab nitrogen nrog Tsawg dua lossis sib npaug li 10ppm O₂, nrog cov kua dej thaub qab rau cov khoom tsis cuam tshuam.

Technical Parameters rau Engineering xaiv

Engineers yuav tsum paub meej tias cov nram qab no interface tsis ua ntej sizing:

• Pub cua txias: Tsawg dua lossis sib npaug li 40 degree, Ntau dua lossis sib npaug ntawm 0.45 MPa (g), CO₂ Tsawg dua lossis sib npaug li 400ppm (tom qab kev lim dej tsawg dua lossis sib npaug rau 1ppm)
• Kev sib cais siab: feem ntau 0.5-2.5 MPa (g). Rau kev tso tawm siab dua, lub twj tso kua mis ua kua + vaporizer yog qhov ua tau zoo dua li qhov nce siab ntawm sab.
• Cov ntaub ntawv tseem ceeb: sab hauv hauv aluminium alloy 5052/5083; lub ntsiab tshav kub exchanger nyob rau hauv aluminium-magnesium alloy; cryogenic li qub nrog txuas ntxiv lub kaus mom.
• Kev tswj hwm qhov system: DCS kev koom ua ke nrog cov roj chromatograph online, oxygen concentration interlock, thiab lub thawv txias qib tswb.

Txheej Txheem Flow Diagram (Text Description)

Cua kom tsawg → tus kheej- ntxuav lim → centrifugal compressor → ua ntej- chav tsev txias (7 degree) → molecular sieve purification (CO₂/H₂O tshem tawm) → booster turboexpander → lub ntsiab cua sov exchanger → qis distillation kem .

Rau kev siv tshuaj lom neeg, nitrogen feem ntau yog kos los ntawm sab saum toj thiab rov ua dua; oxygen tej zaum yuav xav tau ntxiv compression kom ua tau raws li cov raj xa dej siab.

Kev siv tshuaj lom neeg (Matching Logic, Not Case Studies)

• Coal tshuaj: oxygen ntawm 6.0-8.5 MPa (g) nrog kua thaub qab rau gasifier kev nyab xeeb.
• Ammonia synthesis: roj-dawb nitrogen nrog O₂ cov ntsiab lus qis dua 5ppm.
• Cov tshuaj zoo (piv txwv li, caprolactam): nitrogen Ntau dua lossis sib npaug rau 99.999% purity nrog lub peev xwm siab tshaj plaws.

Engineering Services

Peb xa engineering, tsis yog khoom siv xwb:

• Tsim theem: P&ID, lub thawv txias lub hauv paus teeb duab, thiab daim ntawv tshuav nyiaj li cas tag nrho.
• Kev Ua Haujlwm: argon-shielded vuam hauv lub thawv txias, ua raws li 24-teev kua nitrogen txias kuaj.
• Kev lees paub txog kev ua haujlwm: kev siv hluav taws xob tshwj xeeb thiab lub sijhawm ua haujlwm txhua xyoo (Ntau dua lossis sib npaug li 98%) suav nrog hauv cov ntawv txuas ntxiv, raug rau thib peb- pov thawj ntawm tog.

Shenger Gas - Engineering Logic

Ntawm Shenger Gas, txhua qhov cryogenic ASU rau kev lag luam chemical yog qhov loj me raws li tus neeg siv khoom lub siab downstream -purity-load nkhaus - tsis yog tus qauv qauv. Peb muab cov ntawv txheeb xyuas hydraulic rau sab hauv thiab tuav ntawm - qhov chaw kho lub thawv txias. Txhua lub hom phiaj siv hluav taws xob tau rov ua dua- sim thaum lub sijhawm 72-teev kev lees paub, kom ntseeg tau tias daim ntawv cog lus ua haujlwm sib tw cov ntaub ntawv ua haujlwm tiag tiag.
