Ko te 'kaiarahi' o te ahumahi polyethylene

I panuitia e te Tari Tiaki Pungao me te Whakamahi Matawhānui o te Manatu Ahumahi me te Hangarau Paarongo te rarangi o nga hinonga kaha 'kaiarahi' matua, a ko te Kamupene Petrochemical Dushanzi i tohua hei hinonga 'kaiarahi' ahumahi ethylene.

I te mutunga o Akuhata 2021, ko te kaupapa Tarim ethane-to-ethylene a Dushanzi Petrochemical Company, e whakaputa ana i te 600000 tone o te ethylene ia tau, i tukuna i mua i te waarangi. Koinei tetahi atu waahanga nui mo PetroChina ki te tango i te painga o te whakauru o te taha whakarunga me te heke ki te whakapai ake i te uara o te mekameka ahumahi hau maori me te whakatutuki i te huringa me te whakahou me te whanaketanga matomato me te iti-waohanga. Ko te kaupapa e whakamahi ana i te hangarau ethane steam cracking motuhake i hangaia e PetroChina, e mahi ana i te mahi whakaatu rua ki te arahi i te nui o te uara-nui te whakamahi matawhānui o nga rawa hau maori o te kainga me te whakaiti i te whakawhirinakitanga o te hangarau tukanga ethylene ke. kua whakarārangihia hei kaupapa whakaaturanga ā-motu e Te Komihana Whakawhanake me te Whakahoutanga o te Motu me te Manatu Ahumahi me te Hangarau Paarongo. Ka whakatauritea ki te hanga o te ethylene mai i nga rauemi mata wai tuku iho penei i te naphtha tuku iho, ka taea te whakanui ake i te hua ethylene o tenei kaupapa mai i te 30% ki te 80%, ka taea te whakaheke i te utu neke atu i te 30%, me nga tohu ohaoha me nga hangarau matua penei i te ethylene yield me te kohi hiko matawhānui ka eke ki te taumata teitei o te ao.

E ai ki te korero ko te kaha o te kaha o nga ahumahi whiriwhiri 'mua-kaiwhakahaere' ko te tukatuka hinu hinu, te ethylene, te haukini waihanga, te methanol, te houra, te houra pungarehu, te p-xylene, te konupūmā carbide, te coking, te rino me te rino, te whakarewa parahi, te whakarewa konutea, te whakarewa mata, te ciment me etahi atu ahumahi 1452, he maha nga umanga kua tohua.
