Nhau Dzinopisa: Daqing Oilfield's Landmark 200 MMSCFD TEG Unit Yava Pedyo Nekupera muSichuan
Iyo 200 MMSCFD Chigadzirwa cheTEG chekubvisa mvura mumuviri yeDaqing Oilfield's LNG liquefaction plant muWusheng County, Guang'an, Sichuan, ikozvino yava muchikamu chekupedzisira chekuisa. Chirongwa ichi chakarongerwa kuendeswa muna Chikunguru mushure mekutanga kugadzirwa kwaKurume, chimwe chezviteshi zvikuru zvegasi muChina - chinoshandisa tekinoroji yekunyudza triethylene glycol (TEG) kubvisa hunyoro kubva mugasi rechisikigo, ichivimbisa kusimba kwepaipi uye kusangana nezvinodiwa zveLNG feedstock. Nguva iyi inoenderana nekubudirira kwaDaqing munguva pfupi yapfuura mukushaya mvura yakawanda mumafuta (mitengo yakaderedzwa ne80% kuburikidza nemaitiro e thermo-electrochemical)5, ichiratidza kutarisisa kwayo kaviri pakugadzirisa zviwanikwa zvemazuva ano uye zvisina kujairika.
Nei TEG Ichitonga:
- Kushanda Nesimba Uye Kukwanisa Kukura: Zvikamu zveTEG zvinosvika padanho redova riri pasi pe -40°C, zvakakosha kuti kunyunguduka kwemvura.
- Kuwedzera Kwemusika: Kutengeswa kwepasi rose kweTEG kushaya mvura mumuviri kwakasvika $874M muna 2024, zvichifungidzirwa kuti zvichasvika $1.3B panosvika 2031 (6.2% CAGR). China iri kutungamira kudiwa kweAPAC, zvichikonzerwa nekuwedzera kwegasi reshale neLNG.
Maonero eIndasitiri:
Nekunge SLB, CECO, neSichuan Goldstar zviri kutonga macheni ekutengesa, chirongwa cheDaqing cheWusheng chinopa muenzaniso wekushandiswa kwemodular, ine simba rakawanda. Sezvo vashandi vachikoshesa kuderedzwa kweOPEX—vachitevedzera dhizaini yeTEG yeDaqing yekuti "*makore matatu ekugadzirisa, hupenyu hwemakore makumi maviri*"—kugona kwehunyanzvi hwetekinoroji kunzvimbo dziri kure nedziri kure kuchakurumidzisa kushandiswa.
Pfungwa Yechokwadi:
Kukunda kwaDaqing muSichuan hakusi kungori chiitiko chikuru chepurojekiti chete—ipfungwa yekutonga kweChina muzvivakwa zvegasi. Tarisai kuti zvigadzirwa zvitsva zveTEG (semuenzaniso, sub-25mg/Nm³ glycol loss systems) zvichatonga nzvimbo dzinotevera dzekubvisa carbonization hubs.
