He kaupapa whakaora hau hiku styrene tēnei, nā AIR LIQUIDE (Shanghai Industrial Gas Co., Ltd.). E whakamahi ana i te hangarau mimiti pēhanga Skid-mounted hei whakaora i te hauwai mai i te hau hiku whakaputa styrene. Ko te kaha tukatuka kua hoahoatia mō te waeine he 2,500 Nm³/h, e whakahaere ana i te hau hiku mai i te tipu styrene. Ko ngā wāhanga matua o tēnei hau ko te hauwai, te benzene, te toluene, te ethylbenzene, me ētahi atu matū waro. Ka whakamahia e te pūnaha he tukanga whakakotahi "maimoatanga-mua + PSA". Kei roto i te waeine maimoatanga-mua ngā mahi pēnei i te whakapūpū me te mimiti, e tango pai ana i ngā matū benzene mai i te hau hiku me te tiaki i te kaimomo PSA. Ka whakamahia e te waeine PSA he whirihoranga ono-pou, me te parakore o te hauwai hua e eke ana ki te 99.5%, ā, ko te tere whakaora hauwai neke atu i te 80%. Ko te rahinga whakaora hauwai o ia rā he 60,000 Nm³. Kua hangaia te waeine i roto i te whirihoranga pou-mau, me te pūnaha katoa e hangaia ana, e whakamatautauria ana i roto i te wheketere, ā, me hono noa ngā paipa tomo me te putanga me ngā ratonga ratonga ki te papaanga. E rua wiki noa iho te wā tāutanga. Mā te tono angitu o tēnei waeine pou-mau ka whakaratohia he otinga ngāwari me te whai hua mō te whakamahinga rauemi o te hau hiku i roto i ngā umanga hinu-matū, he mea tino pai mō ngā āhuatanga he iti te whenua, he hiahia rānei kia tere te whakatinanatanga.
