Kua tīmata te kaupapa ethylene a ExxonMobil Huizhou i te hanganga o te LDPE 500,000 tana ia tau.

I te Whiringa-ā-rangi 2021, i whakahaerehia e ExxonMobil Huizhouetirenei tū tētahi mahi hanga whānui, hei tohu i te whakaurunga o te wāhanga whakaputa o te kaupapa ki te wāhanga hanga ōkawa whānui.

Ko te Kaupapa Ethylene ExxonMobil Huizhou tētahi o ngā kaupapa nui e whitu i utua e tāwāhi i te motu, ā, koinei hoki te kaupapa matū hinu nui tuatahi e puritia katoatia ana e tētahi kamupene o Amerika i Haina. E whakamaheretia ana kia oti te wāhanga tuatahi, ā, kia whakamahia i te tau 2024.

Kei te Rohe Matū Matū o Daya Bay, Huizhou te kaupapa. Ko te haumitanga katoa o te kaupapa he tata ki te 10 piriona tāra US, ā, e rua ngā wāhanga o te hanganga katoa. Kei roto i te wāhanga tuatahi o te kaupapa he waeine pakaru mamaoa whāngai ngāwari me te putanga ā-tau o te 1.6 miriona tāne o te ethylene, e rua ngā huinga waeine polyethylene iti-kiato raina teitei me te putanga ā-tau katoa o te 1.2 miriona tāne, me te waeine polyethylene iti-kiato me te putanga ā-tau o te 500,000 tāne o te monomer nui rawa atu o te ao. He tipu polyethylene kiato me ngā huinga e rua o ngā tipu polypropylene teitei-mahi rerekē me te putanga ā-tau o te 950,000 tāne, me te maha o ngā kaupapa tautoko pēnei i ngā teihana mahi-taumaha. I muri i te whakaurunga o te wāhanga tuatahi o te kaupapa ki te mahi, e matapaetia ana ka eke ki te moni whiwhi whakahaere o te 39 piriona yuan ia tau. Kua whakaritea kia tīmata te wāhanga tuarua o te kaupapa i te wā e oti ana te wāhanga tuatahi o te kaupapa me te whakaurunga ki te mahi.

I te marama o Poutū-te-rangi 2022, i whakapiki ake te haumitanga a te Kaupapa Ethylene ExxonMobil Huizhou (Wāhanga I) mā te US$2.397 piriona, ā, i piki ake te haumitanga katoa i te wāhanga tuatahi o te kaupapa ki te US$6.34 piriona.

E whitu ngā mahi kirimana whānui hanga matua kua mahia e te Kamupene Hangarau o Nanjing, tae atu ki tētahi wae tango butadiene 270,000-tana/tau, tētahi wae polyethylene iti-mātotoru pēhanga teitei 500,000-tana/tau, me tētahi wae pūwero. Ko te 500,000-tana/tauLDPEKo te wheketere polyethylene iti-kiato kotahi te nui rawa atu o te ao. Me tino tika te hanga o te tāhuna tauhohenga, he teitei ngā paerewa tāutanga o ngā compressors kawemai, ā, ka eke te pēhanga o ngā paipa pēhanga teitei me te pēhanga tino-teitei ki te 360 ​​MPa. Koinei te mahi tahi tuatahi i waenga i te Nanjing Engineering Company. He wheketere polyethylene iti-kiato kirimana tēnei.
