Ishushu Kwiphephandaba: Iyunithi ye-TEG yeDaqing Oilfield eyi-200 MMSCFD esondela ekugqityweni eSichuan

2025-07-25

I-200 MMSCFD Iyunithi yokuphelelwa ngamanzi emzimbeni ye-TEG Kwisityalo se-Daqing Oilfield's LNG liquefaction eWusheng County, eGuang'an, eSichuan, ngoku sikwinqanaba lokugqibela lokufakelwa. Le projekthi, ecwangciselwe ukuhanjiswa ngoJulayi emva kokuqaliswa kwemveliso ngoMatshi, icwangciselwe ukuhanjiswa ngoJulayi emva kokuqaliswa kwemveliso ngoMatshi, iprojekthi—enye yezona ndawo zinkulu zegesi eTshayina—isebenzisa itekhnoloji yokufunxa i-triethylene glycol (TEG) ukususa umswakama kwigesi yendalo, ukuqinisekisa ukuthembeka kwemibhobho kunye nokuhlangabezana neenkcukacha ze-LNG feedstock. Ixesha lihambelana nokuphumelela kweDaqing kutshanje ekuphelisweni kweoyile eninzi (iindleko zincitshiswe ngama-80% ngeenkqubo ze-thermo-electrochemical)5, igxininisa ukugxila kwayo kabini ekusetyenzisweni kwezixhobo zemveli nezingaqhelekanga.

Kutheni i-TEG Ilawula:

Ukusebenza kakuhle kunye nokukhula: Iiyunithi ze-TEG zifikelela kumaqondo ombethe angaphantsi kwe--40°C, nto leyo ebalulekileyo kwi ukunyibilika kolwelo.
Ukwanda kweMarike: Intengiso ye-TEG yokuphelelwa ngamanzi emzimbeni kwihlabathi liphela ifikelele kwi-$874M ngo-2024, kulindeleke ukuba ifikelele kwi-$1.3B ngo-2031 (6.2% CAGR). I-China ikhokela imfuno ye-APAC, eqhutywa yigesi ye-shale kunye nokwandiswa kwe-LNG.

Imbonakalo yoShishino:

Njengoko i-SLB, i-CECO, kunye ne-Sichuan Goldstar zilawula uthungelwano lokubonelela, iprojekthi kaDaqing iWusheng imisela umzekelo wokusetyenziswa kwezixhobo ezikumgangatho ophezulu. Njengoko abaqhubi bebeka phambili ukunciphisa i-OPEX—belinganisa uyilo lwe-TEG lukaDaqing “*ulondolozo lweminyaka emi-3, ubomi beminyaka engama-20*”—ukuziqhelanisa kobuchwepheshe neendawo ezikude nolwandle kuya kukhawulezisa ukwamkelwa.

Eyona Nto Ibalulekileyo:

Uloyiso lukaDaqing eSichuan aluyonto nje ibalulekileyo kwiprojekthi—luyimbonakaliso yokuzimela kweziseko zophuhliso lwegesi eTshayina. Jonga izinto ezintsha ze-TEG (umz., iinkqubo zokulahleka kwe-glycol ezingaphantsi kwe-25mg/Nm³) eziza kulawula ii-hubs zesizukulwana esilandelayo zokususa i-carbonization.
