Khoom Description

Cov nroj tsuag liquefied natural gas (tseem hu ua LNG tsob nroj) yog ib qho loj - teev ua tiav cov khoom siv uas ua ke nrog cov roj purification thiab cryogenic liquefaction.

Nws lub hauv paus ntsiab lus tseem ceeb yog thawj zaug tshem tawm cov impurities (dej, carbon dioxide, sulfur compounds, hnyav hydrocarbons) los ntawm cov pa roj carbon monoxide, tom qab ntawd txias cov roj purified mus rau ib ncig ntawm -162℃los ntawm ntau theem tub yees kom hloov mus rau hauv cov kua, txo nws qhov ntim los ntawm kwv yees li 600 zaug rau kev khaws cia thiab kev thauj mus los.

Nws tuaj yeem ruaj khov ua tau siab -purity LNG thiab yog cov cuab yeej tseem ceeb rau kev lag luam hluav taws xob thoob ntiaj teb.

Txoj cai ua haujlwm

Cov txheej txheem ua haujlwm ntawm Natural Gas Liquefaction Plant tuaj yeem sau tau raws li xya kauj ruam tseem ceeb: cov pa roj compression → pretreatment (lub cev qhuav dej, desulfurization) → hnyav hydrocarbon tshem tawm → mercury tshem tawm → cryogenic liquefaction → LNG cia → cov khoom tso tawm

Raw gas compression:Raw natural gas (feem ntau ntawm 0.5-5.0 MPa) yog compressed rau 4.0-7.0 MPa los ntawm compressor, muab cov kev mob siab rau kev ua kom huv thiab liquefaction.

Pretreatment (lub cev qhuav dej, desulfurization):Compressed raw gas nkag mus rau hauv pretreatment system. Lub cev qhuav dej (siv molecular sieves) txo cov ntsiab lus dej kom qis dua 1 ppm (kom tsis txhob muaj dej khov thaum lub sij hawm liquefaction); desulfurization (siv amine absorption los yog adsorption) tshem tawm hydrogen sulfide thiab organic sulfur, txo tag nrho cov sulfur kom qis dua 50 ppm (kom tiv thaiv cov khoom siv corrosion thiab catalyst lom).

Hnyav hydrocarbon tshem tawm:Pretreated gas nkag mus rau hauv ib tug fractionation ntauwd los cais hnyav hydrocarbons (ethane, propane, butane, thiab lwm yam) los ntawm boiling point sib txawv, kom ntseeg tau tias hnyav hydrocarbon cov ntsiab lus nyob rau hauv lub pub roj yog qis dua 0.1% (kom tsis txhob solidification thaum liquefaction).

Kev tshem tawm mercury:Gas ntws los ntawm mercury adsorption ntauwd (suav nrog sulfur-impregnated activated carbon) kom txo tau cov ntsiab lus mercury kom qis dua 0.01 ug / Nm³ (kom tiv thaiv corrosion ntawm aluminium alloy tshav kub exchangers).

Cryogenic liquefaction:Purified natural gas nkag mus rau hauv lub liquefaction system (cov thev naus laus zis feem ntau suav nrog C3 / MRC, AP-X, lossis lub voj voog sib xyaw ua ke). Nws tau txais kev sib pauv cua sov nrog ntau- cov khoom siv tub yees (muaj cov nitrogen, methane, ethane, propane, thiab lwm yam) hauv cov khoom siv hluav taws xob sib txawv, maj mam txias los ntawm qhov kub thiab txias mus rau -162 degree, hloov los ntawm cov roj mus rau cov kua LNG.

LNG cia:Liquefied natural gas yog khaws cia rau hauv insulated cryogenic cia tso tsheb hlau luam (ntawm -162℃thiab nyob ze atmospheric siab) kom txo tau evaporation poob.

Cov khoom tsim tawm:LNG yog siv los ntawm cov tso tsheb hlau luam mus rau cov chaw nres tsheb thauj khoom, tom qab ntawd thauj mus rau LNG cov tsheb thauj khoom lossis cov tsheb thauj khoom thauj mus los. evaporated gas (BOG, boil{1}}tawm roj) nyob rau hauv cov txheej txheem cia yog zoo tu qab tso thiab recompressed rau reuse nyob rau hauv lub liquefaction system los yog roj.

Tsawg evaporation poob

Advanced rwb thaiv tsev thev naus laus zis thiab BOG cov txheej txheem rov qab ua kom cov evaporation poob qis dua lossis sib npaug li 0.15% ib hnub, txo cov khoom siv hluav taws xob.

Comprehensive impurity tshem tawm

Ntau -theem purification txheej txheem tshem tawm tag nrho cov teeb meem impurities, kom ntseeg tau tias LNG tsis yog -corrosive thiab haum rau ntev - khaws cia thiab kev thauj mus los.

Lub voj voog ua haujlwm ntev

Thaum ruaj khov, cov nroj tsuag tuaj yeem ua haujlwm tsis tu ncua rau 2-3 xyoos, nrog rau kev teem sijhawm kaw rau kev saib xyuas cov cuab yeej tseem ceeb xws li compressors thiab cov khoom siv hluav taws xob.

Qhov zoo ntawm peb lub tuam txhab cov khoom

1. Refined tsim
