Khoom Description
Cov nroj tsuag compressed natural gas (tseem hu ua CNG tsob nroj) yog ib qho khoom siv ua tiav uas ua ke nrog cov roj purification, compression, thiab cia.
Nws lub hauv paus ntsiab lus tseem ceeb yog ua ntej purify raw natural gas kom tshem tawm cov teeb meem impurities, ces siv multi-theem compressors kom lub siab mus rau 20-25 MPa, hloov nws mus rau high-pressure gas uas yuav khaws cia rau hauv lub tog raj kheej los yog tso tsheb hlau luam.
Nws muaj peev xwm ruaj khov ua tau zoo -CNG zoo thiab yog ib qho ntawm cov khoom siv tseem ceeb rau kev siv roj av hauv kev thauj mus los thiab kev faib hluav taws xob.
Txoj cai ua haujlwm
Cov txheej txheem ua haujlwm ntawm cov nroj tsuag CNG tuaj yeem raug suav hais tias yog tsib kauj ruam tseem ceeb: roj av ua ntej → compression → dehydration & desulfurization → cia → cov khoom tso tawm
Raw gas pretreatment:Raw natural gas (feem ntau ntawm 0.1-1.0 MPa) nkag mus rau hauv lub lim cais kom tshem tawm cov khoom siv, cov dej ua kua, thiab cov roj dawb (los tiv thaiv cov cua compressors los ntawm kev hnav thiab corrosion).
Compression:Pretreated gas yog compressed los ntawm multi-theem reciprocating los yog ntsia hlau compressor. Txhua theem compresses cov roj mus rau 4-6 MPa, nrog intercoolers ntawm theem kom txo qhov kub thiab txias (kom tsis txhob overheating thiab txhim kho compression efficiency), thaum kawg ncav cuag lub hom phiaj siab ntawm 20-25 MPa.
Lub cev qhuav dej & desulfurization:Cov roj compressed nkag mus rau hauv lub tshuab ua kom huv. Lub cev qhuav dej (siv molecular sieves lossis adsorption tshuab ziab khaub ncaws) txo cov ntsiab lus dej kom qis dua 10 ppm (kom tiv thaiv kev tsim cov dej hauv siab - cov kav dej siab); desulfurization (siv cov pa roj carbon activated lossis amine scrubbers) tshem tawm hydrogen sulfide kom qis dua 20 mg / Nm³ (kom tsis txhob muaj cov khoom siv khaws cia thiab lub cav puas).
Cia:Purified siab - siab CNG yog khaws cia rau hauv siab - lub tog raj kheej lub tog raj kheej los yog lub tso tsheb hlau luam, uas yog tsim los tiv taus 20-25 MPa thiab nruab nrog kev nyab xeeb li qub thiab ntsuas ntsuas rau kev ntsuas siab.
Cov khoom tsim tawm:CNG los ntawm cov chaw khaws cia yog muab faib rau cov neeg siv los ntawm kev faib khoom. Rau lub tsheb refueling, lub dispenser txo lub siab mus rau 20 MPa thiab meters cov roj; rau kev lag luam siv, lub siab yog kho raws li tus neeg siv yuav tsum tau ntawm cov regulators siab.
Cov yam ntxwv tseem ceeb
Kev kub siab cia
Ua haujlwm ntawm 20-25 MPa, ua kom muaj peev xwm txo qis rau kev thauj mus los yooj yim thiab khaws cia, tsim nyog rau cov xwm txheej ntawm cov roj hluav taws xob.
01
Saj zawg zog muaj peev xwm
Ib qho -unit txhua hnub kev ua haujlwm muaj peev xwm nyob ntawm 5,000 Nm³ txog 500,000 Nm³, hloov mus rau me me - nplai (cov chaw nres tsheb roj) thiab loj - nplai (cov chaw ua si hauv kev lag luam) xav tau.
02
refueling ceev
Nruab nrog siab -flow dispensers uas tuaj yeem refuel lub tsheb CNG hauv 3-5 feeb, ua tau raws li qhov xav tau ntawm cov chaw thauj mus los tsis khoom.
03
Compact layout
Cov cuab yeej tseem ceeb (compressors, lub tog raj kheej cia, cov tshuab xa tawm) tuaj yeem npaj tau raws li kev hloov pauv, nyob hauv thaj chaw me me, tsim nyog rau kev xa tawm hauv nroog lossis suburban.
04
Tsawg emissions
CNG muaj cov pa roj carbon tsawg dua li cov roj av lossis roj av (kwv yees li 20-30% txo), ua rau cov nroj tsuag muaj cov roj carbon tsawg.
05
Qhov zoo ntawm peb lub tuam txhab cov khoom
Niaj hnub no, raws li daim ntawv thov ntawm lub zog huv si tau nce zuj zus, refined engineering tsim yog ib qho tseem ceeb rau kev ua tau zoo thiab kev nyab xeeb ntawm compressed Natural Gas nroj tsuag. Peb tau tsim ib pab kws tshaj lij engineering nrog ntau tshaj 25 xyoo ntawm kev koom tes hauv kev lag luam ntawm cov pa roj carbon monoxide, ua tiav cov qauv tseem ceeb hauv tsev thiab thoob ntiaj teb thiab cov kev qhia tshwj xeeb xws li ISO, API, ASME, thiab EN. Raws li cov yam ntxwv ntawm cov roj av nyoos (xws li methane piv thiab impurity muaj pes tsawg leeg) thiab daim ntawv thov ib puag ncig (xws li, tsheb refueling lossis industrial gas mov) ntawm cov haujlwm sib txawv, peb muab cov kev daws teeb meem ntawm tus kheej. Peb tsom mus rau optimizing compressor theem configuration, intercooler efficiency, thiab purification system kev sib koom tes, uas yuav txo tau lub zog noj los ntawm 5% -8% piv nrog cov pa schemes. Peb ib txwm ua raws li lub tswv yim ntawm kev hloov kho kom ntseeg tau tias txhua cov nroj tsuag raug phim nws cov kev ua haujlwm tshwj xeeb.
Thoob plaws hauv lub voj voog ua tiav los ntawm kev npaj mus rau commissioning, peb lub tuam txhab ua tiav cov qauv ntawm ISO9001 Kev Tswj Xyuas Zoo thiab ISO14001 Environmental Management System. Nyob rau hauv cov txheej txheem tsim theem, peb siv cov kev tshaj lij software xws li Aspen HYSYS rau compressor system simulation los xyuas kom meej qhov ruaj khov ntawm nws cov kev khiav hauj lwm siab. Tag nrho cov cuab yeej tseem ceeb, suav nrog compressors, siab - siab li qub, thiab cov roj cia qhov dej, raug tshuaj xyuas los ntawm cov neeg sab nraud thib peb- cov koom haum kom ntseeg tau tias ua raws li cov khoom siv siab xws li ASME BPVC Tshooj VIII. High- kev kub siab cov kav dej vuam ua haujlwm nruj me ntsis ua raws li cov txheej txheem kev lees paub, ua ke nrog tsis yog- kev kuaj kev puas tsuaj xws li Ultrasonic Testing (UT) thiab Penetrant Testing (PT), ua kom muaj kev ruaj ntseg sealing ntawm cov pob qij txha. Kev ntsuas kev ruaj ntseg 72-teev yog ua ua ntej ua tiav qhov project kom paub tseeb tias cov cuab yeej ua tau zoo raws li kev ua haujlwm ntws, qhov system siab, thiab roj purity. Cov txheej txheem ua tiav no muab cov kev lav phib xaub rau kev ntseeg siab ntawm qhov project zoo thiab lub sijhawm xa khoom.
Cov khoom lag luam zoo yog lub hauv paus tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ruaj khov ntawm CNG. Txhua tsob nroj ua raws li cov qauv kev tswj hwm nruj: lub tshuab compressor yog nruab nrog ntau yam kev tiv thaiv overload thiab tiag -lub sijhawm ntsuas kub kom ntseeg tau tias kev ua haujlwm tsis tu ncua thiab txhim khu kev qha; siab -cov roj cia cov roj siab yog tsim nyob rau hauv nruj raws li GB 150 los yog ASME specifications nrog lub neej kev pab ntawm tsis pub tsawg tshaj 20 xyoo; cov khoom siv roj lim kom paub tseeb tias cov khoom tsim CNG ua tau raws li cov kev cai ntawm lub teb chaws cov qauv xws li GB 18047, thiab cov khoom tsim nyog tus nqi ib txwm tswj 100%. Qhov teeb meem nruab nrab- lub sijhawm ua haujlwm pub dawb ntawm tag nrho cov khoom siv ntau tshaj 8000 teev, muab kev txhawb zog rau kev ua haujlwm ntev - lub sijhawm ua haujlwm tau zoo.
Txhawm rau kom ntseeg tau tias cov khoom siv txuas ntxiv thiab ruaj khov ntawm CNG, siab - zoo tom qab - kev muag khoom yog qhov tseem ceeb heev. Tom qab tau txais qhov kev thov kev pabcuam los ntawm tus neeg siv, peb pab pawg pabcuam kev pabcuam yuav ua haujlwm tam sim 24/7 cov lus teb thiab cog lus tias yuav muab cov lus teb thawj zaug hauv 8 teev los ntawm kev hu xovtooj, emails, lossis ntawm - qhov chaw tshawb fawb. Rau cov teeb meem daws teeb meem xws li kev hloov siab thiab ntsuas lub tswb, peb lav tias yuav pab ua kom tiav cov haujlwm hauv 24 teev; nyob rau hauv cov ntaub ntawv ntawm kev ua tsis tau tejyam uas yuav tsum tau nyob rau ntawm - qhov chaw daws teeb meem, engineers tuaj yeem xa mus rau cov chaw hauv tsev tsis pub dhau 48 teev thiab cov chaw thoob ntiaj teb hauv 72 teev. Tsis tas li ntawd, peb muab cov kev pabcuam tu vaj tse nrog rau kev hloov roj compressor thiab lim tu kom zoo rau kev siv lub neej ntawm cov khoom siv.
Peb cov Compressed Natural Gas Plants tau ua kom pom kev ntseeg tau zoo thiab kev ua haujlwm zoo hauv cov ntawv loj - cov ntawv thov kev lag luam, thiab tau lees paub los ntawm ntau lub tuam txhab ua lag luam hauv kev lag luam hluav taws xob thiab kev thauj mus los, suav nrog cov tuam txhab nto moo thoob ntiaj teb xws li PetroChina, Sinopec, Gazprom, thiab cov tuam txhab roj huv huv.
Hais txog txoj kev koom tes, peb tsis tsuas yog muab tag nrho - txheej txheem xa khoom xa tuaj nrog rau kev tsim, kev teeb tsa, thiab kev ua haujlwm tab sis kuj muaj cov qauv hloov pauv xws li cov khoom siv xauj lossis cov ntawv cog lus roj (peb yog lub luag haujlwm rau kev cog qoob loo thiab muab CNG rau cov neeg siv khoom) raws li cov neeg siv khoom xav tau, pab cov neeg siv khoom xaiv cov peev txheej tsim nyog rau lawv tus kheej cov xwm txheej.
