He wāhanga wehewehe hau tēnei kaupapa mō teTe tipu pakaru olefin 100,000-tana/tau, e whai ana kia whakahokia mai ngā rauemi hauwai nui te uara mai i te hau hiku e pakaru ana. Ka whakamahia e te kaupapa te hangarau tango hauwai pēhanga pēhanga (PSA) i hangaia mō ngā pūtake hau hauwai iti. Ko te ihirangi hauwai i roto i te hau mata kua tukatukahia he 17% noa iho, he āhuatanga noa iho tēnei ote whakaora hauwai iti-kukūi roto i te umanga. Ko te kaha tukatuka kua hoahoatia o te taputapu he12,000 Nm³/h, ā, e whakamahi ana i te whirihoranga tukanga PSA tekau-pou. Ka eke te parakore o te hauwai hua ki99.9%, ā, ko te tere whakaora hauwai kua hipa ake i te85%.Ka whakamahia e te pūnaha PSA tētahi rautaki ōwehenga mimiti me te whakahaere wā ahurei hei whakarite i te whakaora hauwai whai hua ahakoa i raro i ngā āhuatanga kukū hauwai iti. Ko te wā hanga i te papaanga he 6 marama, ā, ka whakamahia te hoahoa modular, e āhei ai te hanga i mua i te wheketere me te tāutanga tere i te papaanga.

Mai i tōna tīmatanga i te tau 2020, kua ora ake tēnei taputapu i ngā tau maha80 miriona Nm³ o te hauwai ia tau, ka whakaiti nui i te whakamahinga rauemi o te whare hanga olefin, ā, ka whakarei ake i ngā hua ōhanga whānui.
