He kaupapa whakahou tēnei mō te tipu propylene o Shenyang Paraffin Chemical Co., Ltd., e whai ana kia whakahokia mai te hauwai mai i te hau hiku hauwai methane me te whakapai ake i te whakamahinga rauemi. Ko te kaha tukatuka kua hoahoatia mō te waeine he500 Nm³/hKa whakamahia e ia te hangarau pēhanga pupuhi (PSA) hei pure i te hauwai mai i te ranunga hauwai methane i hangaia e te tipu propylene. Ko te nui o te hauwai i roto i te hau mata he tata ki40-50%, ā, ko te nui o te methane he tata ki50-60%I muri i te purenga PSA, ka taea e te hauwai o te hua te eke ki teneke atu i te 99.5%, e whakatutuki ana i te hiahia hauwai o ētahi atu wāhanga i roto i te wheketere.

E ono ngā pourewa o te wāhanga PSA, ā, he tāke ārai hau mata me te tāke ārai hau hua hei whakarite kia maeneene te mahi a te wāhanga. Ko te wā hanga i te papaanga o te kaupapa whakahoutanga he2 maramaKua whakamahia katoatia ngā whare wheketere taketake me ngā hanganga, ā, kua hangaia ngā taputapu hou kia rite ki te āhua e mau ana ki te reti hei whakaiti i te pānga ki te hanga o nāianei.

I muri i te whakatinanatanga o te kaupapa whakahoutanga, ka nui ake te nui o te hauwai i kohia i ia tau4 miriona Nm³, te whakatutuki i te whakamahinga whai hua o ngā rauemi hau hiku me te whakaiti i te whakapaunga pūngao katoa a te wheketere.
