Kufotokozera Zamalonda
Malo olekanitsa gasi (omwe amadziwikanso kuti fakitale yogawa gasi) ndi zida zonse zomwe zimalekanitsa ndi kuyeretsa-magawo ambiri agasi kukhala ma hydrocarbon.
Mfundo yake yaikulu ndikugwiritsa ntchito kusiyana kwa malo otentha pakati pa methane (-161.5 digiri), ethane (-88.6 digiri), propane (-42.1 digiri), ndi zigawo zina, kupyolera mu njira monga kuzizira kwa cryogenic, kulamulira mphamvu, ndi distillation, kuti akwaniritse kulekanitsa kwapang'onopang'ono kwa gawo lililonse.
Imatha kutulutsa-ma hydrocarboni amtundu umodzi wokwera kwambiri ndipo ndi chida chofunikira kwambiri pakugwiritsa ntchito bwino gasi.
Mfundo yogwira ntchito
Njira yogwirira ntchito yolekanitsa gasi ikhoza kufotokozedwa mwachidule ngati masitepe asanu ndi limodzi: kuponderezedwa kwa gasi yaiwisi → preatment → kuzizira kwa cryogenic → kupatukana kwa distillation → kuyeretsa chigawo → kutulutsa kwazinthu
Kupanikizika kwa gasi:Gasi wachilengedwe (nthawi zambiri pa 1.0-5.0 MPa) amapanikizidwa mpaka 3.0-8.0 MPa kudzera pa kompresa, kupereka mikhalidwe yokakamiza kuti apatukane.
Kuchiza:Mpweya woponderezedwa umalowa m'dongosolo loyeretsera kuti achotse zonyansa monga madzi, carbon dioxide, hydrogen sulfide, ndi mercury (kupewa kuwononga zida, kuzizira, kapena kuyambitsa poizoni panthawi ya cryogenic).
Kuzizira kwa Cryogenic:Mpweya wokonzedweratu umakhazikika mpaka -40 digiri ~ -100 digiri kudzera mu makina osinthira kutentha (pogwiritsa ntchito firiji kapena mphamvu yozizira kuchokera kuzinthu zolekanitsidwa), kutulutsa pang'ono ma hydrocarbon olemera (propane, butane, etc.) ndikusunga methane mu mpweya.
Kupatukana kwa distillation:Gasi woziziritsidwa-osakaniza wamadzimadzi amalowa m'njira zambiri-zosanja distillation tower (deethanizer, depropanizer, debutanizer, etc.). Mu deethanizer, ethane ndi zigawo zopepuka zimasiyanitsidwa ndi propane ndi ma hydrocarbon olemera kwambiri; mu depropanizer, propane imasiyanitsidwa ndi zigawo za butane ndi zolemera kwambiri, kukwaniritsa sitepe-ndi-kulemeretsa gawo lililonse.
Kuyeretsa chigawo:Chigawo chilichonse chopatulidwa (methane, ethane, propane) chimayeretsedwanso (monga kutsatsa kapena kuvula) kuchotsa zonyansa, kuwonetsetsa kuti chinthu chomaliza chikugwirizana ndi miyezo (mwachitsanzo, methane ya gasi wapaipi, ethane/propane monga petrochemical feedstock).
Zotulutsa:Methane yoyeretsedwa imasinthidwa ku mphamvu ya mapaipi ndikuperekedwa kuti iyendetse; ethane, propane, ndi butane mwina zimasungidwa ngati zamadzimadzi pansi pa kupanikizika kapena kusinthidwa kukhala LPG, ethylene feedstock, ndi zina zotero, kutengera zosowa za ogwiritsa ntchito.

Zambiri-zolekanitsa zigawo
Imatha kulekanitsa nthawi imodzi methane, ethane, propane, butane, ndi ma hydrocarbons ena, kukulitsa kugwiritsa ntchito bwino gasi.
01
Kuyera kwakukulu kwazinthu
Kuyeretsedwa kwa zigawo zikuluzikulu zolekanitsa ndizokhazikika, ndi methane Wamkulu kuposa kapena wofanana ndi 95% (miyezo ya gasi yokumana ndi mapaipi), ethane Wamkulu kuposa kapena wofanana ndi 90% (yoyenera kupanga ethylene), ndi propane Wamkulu kuposa kapena wofanana ndi 95% (oyenerera LPG).
02
Chachikulu processing mphamvu
Kuchuluka-pang'onopang'ono kumayambira 50,000 Nm³ mpaka 1,000,000 Nm³, kutengera malo apakati ndi akulu{6}}pamalo opangira gasi kapena malo opangira mafuta.
03
Kugwira ntchito mosalekeza
Ikangoyenda mosasunthika, imatha kugwira ntchito mosalekeza kwa zaka 2-3, ndikuzimitsa komwe kumakonzedwera kukonza nsanja zopangira distillation, zosinthira kutentha, ndi zida zina zofunika.
04
Kugwiritsa ntchito mphamvu zamagetsi
Amaphatikiza machitidwe obwezeretsa kutentha kuti agwiritsenso ntchito mphamvu zoziziritsa kuzinthu za cryogenic, kuchepetsa kugwiritsa ntchito mphamvu zonse ndi 10-15% poyerekeza ndi mapangidwe wamba.
05
Ubwino wazinthu zamakampani athu
M'nthawi yogwiritsira ntchito bwino zinthu, mapangidwe oyengedwa ndiye maziko owonetsetsa kuti kulekanitsa bwino komanso kukhazikika kwa magwiridwe antchito. Kampani yathu ili ndi gulu la akatswiri odziwa zaukadaulo omwe ali ndi zaka zopitilira 25 pakugwiritsa ntchito gasi wachilengedwe, odziwa bwino miyezo yapakhomo ndi yapadziko lonse lapansi monga GB, API, ASME, ndi ISO. Timapereka mapangidwe makonda zochokera yaiwisi mpweya zikuchokera (mwachitsanzo, hydrocarbon okhutira chiŵerengero) ndi kulekana zofunika (mwachitsanzo, chandamale zigawo zikuluzikulu), optimizing distillation nsanja dongosolo, kusankha refrigerant, ndi maukonde kutentha kuwombola kusintha chigawo kuchira mitengo (ethane kuchira Wamkulu kuposa kapena wofanana 90%, propane kuchira Wamkulu kuposa kapena wofanana 95%). Timasiya ma tempuleti okhazikika ndikupanga mapangidwe atsatanetsatane a projekiti iliyonse kuti agwirizane ndi mawonekedwe apadera a gasi.
Kampani yathu imagwiritsa ntchito mosamalitsa kasamalidwe kabwino ka ISO9001 munthawi yonse ya moyo wa polojekiti, kupanga mapangidwe, kugula, kumanga, ndi kutumiza. Pa gawo la mapangidwe, kuyerekezera kwadongosolo kumatsimikizira kulekanitsa bwino komanso kugwiritsa ntchito mphamvu; zida zofunika kwambiri (nsanja zopangira distillation, kompresa, zotenthetsera) zimawunikiridwa ndi gulu lachitatu kuti zitsimikizire kuti zikutsatira zotengera zotengera mphamvu; kumanga kumatsatira njira zowotcherera (ndi satifiketi ya WPS/PQR) komanso -kuyesa kosawononga (UT, RT) kwa mapaipi a cryogenic; Kutumiza kumaphatikizapo kuyezetsa ntchito mosalekeza kwa maola 72-kutsimikizira kuyera kwazinthu, kuchuluka kwa kuchira, ndi zizindikiro zogwiritsa ntchito mphamvu. Kuwongolera mwadongosolo kumeneku kumatsimikizira kuti projekiti ikhale yabwino komanso yopereka nthawi yake.
Timawona kuti zinthu zili bwino ngati gwero la bizinesi, kudzipereka kumapereka -mafakitale odalirika olekanitsa. Chomera chilichonse chimayang'aniridwa mosamalitsa: zida za cryogenic (mwachitsanzo, 304L zitsulo zosapanga dzimbiri) zimakwaniritsa zofunikira zotsika-zolimba kutentha (kuyesa kwamphamvu Kuposa kapena kofanana ndi 27 J pa -196 digiri); distillation tower internals (mathireyi, kulongedza) amasankhidwa kuti azisiyanitsa bwino kwambiri ndi moyo wautumiki wa Kuposa kapena wofanana ndi zaka 10; moyo wonse wa mapangidwe a zomera ndi Waukulu kuposa kapena wofanana ndi zaka 20, ndi ntchito yokhazikika ya Kuposa kapena yofanana ndi 95% (kupatula kukonza). Timapereka zikalata zotsimikizira zamtundu wathunthu, kuphatikiza ziphaso zakuthupi, malipoti oyesa ntchito, ndi zolemba zogwirira ntchito.
Kuchita bwino pambuyo pa-ntchito zogulitsa ndikofunikira kuti kampaniyo igwire ntchito mosalekeza. Tikalandira pempho lautumiki, gulu lathu laukadaulo limapereka mayankho oyambira mkati mwa maola 12 (24/7) kudzera pa foni, imelo, kapena msonkhano wamakanema, kuphatikiza kuzindikira kwamavuto ndi mayankho oyambira. Pazifukwa zakutali-zomwe zingathetsedwe (monga kusintha magawo), timawongolera kutha pasanathe maola 24; pa{10}}zofuna kukonza malo, mainjiniya amatumizidwa mkati mwa maola 48 (zanyumba) kapena maola 72 (zadziko lonse) atatsimikizira zomwe akufuna. Timaperekanso ntchito zodzitetezera nthawi zonse (mwachitsanzo, kuyang'anira anthu a pansanja, kusintha kothandizira) kuti muchepetse nthawi yopuma.
Kampani yathu imatha kupereka zida zamafakitale olekanitsa gasi monga makonda a EPC (Engineering, Procurement, Construction) turnkey mapulojekiti, komanso ntchito zaukadaulo monga kukhathamiritsa kwazinthu komanso maphunziro oyendetsa. Izi zimathandiza makasitomala kusankha njira yabwino kwambiri yothandizirana potengera zosowa zawo.
