Kei waho o te Pāpāho: Kua tata te otinga o te waeine TEG 200 MMSCFD rongonui o te mara hinu o Daqing i Sichuan

Te 200 MMSCFD Wāhanga whakamaroke TEG mō te tipu wairewa LNG o Daqing Oilfield i Wusheng County, Guang'an, Sichuan, kei roto i ngā wāhanga tāutanga whakamutunga. Kua whakaritea kia tukuna i te marama o Hūrae i muri i te tīmatanga o te whakaputanga o Poutū-te-rangi, ka whakamahia e tēnei kaupapa—tētahi o ngā pokapū hau nui rawa atu o Haina—te hangarau mimiti triethylene glycol (TEG) hei tango i te makuku mai i te hau māori, hei whakarite i te pono o ngā paipa me te tutuki i ngā whakaritenga rauemi LNG. E hangai ana te wā ki te putanga hou a Daqing i roto i te whakamaroke hinu taumaha (kua whakahekehia ngā utu mā te 80% mā roto i ngā tukanga thermo-electrochemical)5, e whakaatu ana i tana arotahi rua ki te arotau rauemi tikanga me te kore tikanga.

He aha i kaha ai a TEG:

• Te Whai Hua me te Tauine: Ka eke ngā waeine TEG ki ngā tohu tomairangi i raro i te -40°C, he mea nui mō te waimeha.
• Te Pikinga o te Mākete: I eke te hokonga waikura TEG o te ao ki te $874M i te tau 2024, e matapaetia ana ka eke ki te $1.3B i te tau 2031 (6.2% CAGR). Ko Haina te kaiārahi o te tono o te APAC, nā te whakawhānui o te hau shale me te LNG.

Tirohanga Ahumahi:

I te mea ko SLB, CECO, me Sichuan Goldstar te rangatira o ngā mekameka tuku, ka whakatakoto te kaupapa Wusheng a Daqing i tētahi tauira mō ngā whakatinanatanga modular, teitei-kaha. I te mea e whakatairanga ana ngā kaiwhakahaere i te whakaiti OPEX—e whai ana i te hoahoa TEG "*3-tau tiaki, 20-tau te roa*" a Daqing—ka tere ake te whakamahi i te urutau o te hangarau ki ngā wāhi taiwhenua me ngā wāhi tawhiti.

Ko te Whakamutunga:

Ehara i te mea he kaupapa nui noa iho te wikitoria o Daqing i Sichuan—he mahere mō te mana motuhake o ngā hanganga hau o Haina. Kia mataara ki ngā mahi auaha a TEG (hei tauira, ngā pūnaha ngaronga glycol iti iho i te 25mg/Nm³) hei whakahaere i ngā pokapū whakakore waro o te whakatupuranga e whai ake nei.
