Okushisayo Kwabezindaba: Iyunithi ye-TEG ye-Daqing Oilfield engu-200 MMSCFD isondela ekuqedweni eSichuan

2025-07-25

I-MMSCFD engu-200 Iyunithi yokuphelelwa amanzi emzimbeni ye-TEG Isitshalo se-Daqing Oilfield sokukhipha uketshezi lwe-LNG eWusheng County, eGuang'an, eSichuan, manje sisesigabeni sokugcina sokufakwa. Njengoba kuhlelwe ukuthi kuthunyelwe ngoJulayi ngemuva kokuqala kokukhiqiza ngoMashi, lo msebenzi—omunye wezindawo ezinkulu kakhulu zegesi ezisogwini lwaseShayina—usebenzisa ubuchwepheshe bokumunca i-triethylene glycol (TEG) ukususa umswakama kugesi yemvelo, ukuqinisekisa ubuqotho bombhobho kanye nokuhlangabezana nemininingwane ye-LNG feedstock. Isikhathi sihambisana nentuthuko yakamuva kaDaqing ekuphelelweni kwamanzi kakhulu kwamafutha (izindleko zincishiswe ngo-80% ngezinqubo ze-thermo-electrochemical)5, okubonisa ukugxila kwayo okubili ekwenzeni ngcono izinsiza ezivamile nezingavamile.

Kungani i-TEG Ibusa:

Ukusebenza Kahle Nokukhula: Amayunithi e-TEG afinyelela amaphuzu amazolo ngaphansi kuka--40°C, okubalulekile kakhulu ukuncibilikisa uketshezi.
Ukwanda Kwemakethe: Ukuthengiswa kokuphelelwa amanzi emzimbeni kwe-TEG emhlabeni wonke kufinyelele ku-$874M ngo-2024, okulindelwe ukuthi kufinyelele ku-$1.3B ngo-2031 (6.2% CAGR). I-China ihola isidingo se-APAC, esiqhutshwa ukwanda kwegesi ye-shale kanye ne-LNG.

Umbono Wemboni:

Njengoba i-SLB, i-CECO, kanye ne-Sichuan Goldstar zilawula izintambo zokuphakelwa, iphrojekthi kaDaqing iWusheng ibeka isibonelo sokusetshenziswa kwezinhlelo ezisezingeni eliphezulu. Njengoba opharetha bebeka phambili ukuncishiswa kwe-OPEX—belandela ukwakheka kwe-TEG kaDaqing “*ukulungiswa kweminyaka emi-3, impilo yeminyaka engama-20*”—ukuzivumelanisa kobuchwepheshe nezindawo zasogwini kanye nasezindaweni ezikude kuzosheshisa ukwamukelwa.

Iphuzu Eliyinhloko:

Ukunqoba kukaDaqing eSichuan akuyona nje ingqophamlando yephrojekthi—kuyisibonelo sobukhosi bengqalasizinda yegesi yaseShayina. Qaphela izinto ezintsha ze-TEG (isb., izinhlelo zokulahlekelwa yi-sub-25mg/Nm³ glycol) ezizobusa izindawo zokususa i-carbonization zesizukulwane esilandelayo.
