Dabere na nyocha miri emi nke China's Ethylene Glycol Industry Development na Future Investment Research Report (2022-2029) nke Guanyan Report Network wepụtara, n'afọ ndị na-adịbeghị anya, ụlọ ọrụ ethylene glycol zuru ụwa ọnụ etolitela ngwa ngwa, yana ikike nrụpụta ethylene glycol na mmepụta na-abawanye afọ. site n'afọ.Na 2021, ikike mmepụta ethylene glycol zuru ụwa ọnụ ga-abawanye site na 19.4% kwa afọ, na mmepụta ga-abawanye site na 7.5% kwa afọ.N'okpuru ndabere a, ikike mmepụta na mmepụta nke ụlọ ọrụ ethylene glycol nke China na-abawanye kwa afọ.
N'ihe banyere ikike mmepụta, ka mba ahụ na-etinyekwu uche na ụlọ ọrụ ethylene glycol, nduzi dị mkpa na nkwado nkwado dị ka Formula maka Ịkwalite nkwalite na Ngwa nke Teknụzụ na Ngwaahịa na Petrochemical na Chemical Industry na 2021, Atụmatụ Nduzi na Ịkwalite The High Quality Development of Petrochemical and Chemical Industry n'oge "Atụmatụ nke iri na anọ nke ise" na echiche nduzi na High Quality Development nke Chemical Fiber Industry na 2022 na-aga n'ihu na-enye, na ụlọ ọrụ amụma gburugburu ebe obibi na-anọgide na-adị mma, China ethylene glycol. ikike mmepụta na-abawanye kwa afọ.Dị ka data ahụ si kwuo, ikike mmepụta ethylene glycol nke China ga-abawanye site na nde tọn 8.32 ruo nde tọn 21.45 site na 2017 ruo 2021, yana nkezi uto ngwakọta kwa afọ nke ihe dịka 31%.
N'ihe banyere ike itinye ego n'ọrụ, mkpokọta ojiji nke ethylene glycol ikike na China dị ala ugbu a, nke bụ ihe dịka 68.63% na 2017;Ọ ga-abawanye ruo 73.42% site na 2019. Otú ọ dị, site na 2020 ruo 2021, n'ihi mmetụta nke mwepu ọrịa n'ụlọ, ethylene glycol ngwaọrụ mmezi, ike rationing na elu coal ọnụ ahịa, ụlọ ethylene glycol amalite ibu dị ala, na n'ozuzu ya. Ụlọ ọrụ na-amalite ibelata nke ukwuu, na-eme ka ọnụego ojiji ethylene glycol na China na-agbada ruo 60.06% na 55.01% n'otu n'otu n'ime afọ abụọ gara aga.
N'ihe banyere mmepụta, na mgbasawanye nke ethylene glycol ike ahịa na mmụba n'ozuzu nke ọchịchọ ala ala, mmepụta ahụ na-egosikwa usoro nke uto kwa afọ.Site na 2017 ruo 2021, mmepụta ethylene glycol nke China mụbara site na nde tọn 5.71 ruo nde tọn 11.8, ọnụego uto ya gosikwara nrịgo elu n'ime afọ abụọ gara aga, nke nnukwu uto nke ikike nrụpụta ya na-akwalite.Na 2021, ọnụego mmepụta ethylene glycol nke China bụ ihe dịka 21.65% kwa afọ, pasent 2.63 dị elu karịa nke ahụ na 2020.
Site na ngbanwe nke ikike mmepụta nke ethylene glycol nke China, enwere ike ịhụ na ikike mmepụta ethylene glycol nke China emeela ka ọ dịkwuo mma n'ime afọ ise na-adịbeghị anya, ụlọ ọrụ ahụ nọkwa na-eto eto na mmepe.
N'ihe gbasara usoro ụlọ ọrụ, e nwere usoro mmepụta atọ nke ethylene glycol na China: ntinye (usoro naphtha / ethylene), MTO (methanol ka olefin) na coal na ethylene glycol.Ka ọ dị ugbu a, n'ihi nkà na ụzụ nwere nkà nke petroleum na ethylene glycol na China, nke bụ ụzọ a na-ejikarị eme ihe, ikike imepụta mmanụ na ethylene glycol bụ nke kachasị elu.Na 2021, ikike mmepụta mmanụ na ethylene glycol na China ga-aza ihe karịrị 60%, na mmepụta ga-agafe 7 nde tọn;Nke abụọ bụ coal ka ethylene glycol technology (ụzọ coal bụ iji coal synthesis gas na mbụ, na mgbe ahụ na-eji mmiri na carbon monoxide na synthesis gas dị ka akụrụngwa iji kwadebe ethylene glycol), na mmepụta ikike na-aza ihe karịrị 30% na mmepụta ihe karịrị nde tọn atọ.Ọnụ ego mmanụ ebiliwo n'ime afọ abụọ na-adịbeghị anya, na mmepụta nke coal na ethylene glycol na China amụbawo ngwa ngwa.Na 2021, mmepụta nke coal na ethylene glycol na China ga-eto ihe dịka 50% kwa afọ.Dị ka China nwere usoro ume nke "coal ọzọ, obere gas na obere mmanụ", coal na ethylene glycol bụ njirimara China n'ihe gbasara mkpokọta ethylene glycol na China.N'ọdịnihu, coal China na ethylene glycol nwere nnukwu ikike mmepe.
