I puta ake te whakaaro o ngā kairangahau o Te Whare Wānanga o Chung-Ang i Kōrea ki te Tonga ki te whakamahi i te hauhā waro ahumahi me te dolomite, he toka parataiao noa, he whānui hoki te horapa, he nui te konupūmā me te konupora, hei whakaputa i ngā hua e rua e whai hua ana ki te hokohoko: te konupūmā formate me te konupora waikura.
I roto i tētahi pepa i whakaputaina ki te Journal of Chemical Engineering, e whakamārama ana ngā kaipūtaiao ko tā rātou hangarau hopu me te whakamahi waro (CCU) e hangai ana ki tētahi tukanga e whakakotahi ana i ngā tauhohenga hauwai waro hauhā me ngā tauhohenga whakawhiti kationa hei pure i ngā waikura whakarewa me te whakaputa i te hanga hōputu uara nui, uara nui.
Ina koa, i whakamahia e rātou he whakakorikori (Ru/bpyTN-30-CTF) hei tāpiri i te hauwai ki te hauhā waro, ka puta ai he hua uara tāpiri e rua. Ka whakamahia hoki e te whakakorikori kiri te konupūmā formate, ngā tāpiringa sima, ngā deicers me ngā tāpiringa kai kararehe. I tētahi atu taha, he whānuitia te whakamahinga o te konupūmā waikura i roto i ngā ahumahi hanga me te rongoā.
E ai ki ngā kairangahau matua a Seongho Yoo rāua ko Chul-Jin Lee, ehara i te mea ka taea anake te mahi, engari he tino tere hoki, ka puta te hua i roto i te rima meneti noa iho i te pāmahana rūma. Hei tāpiri, e whakatau ana tana tīma ka taea e te tukanga te whakaiti i te kaha o te mahana o te ao mā te 20% ki te whakataurite ki ngā tikanga tuku iho o te whakaputa konupūmā formate.
I aromatawaihia hoki e te tīma mēnā ka taea e tā rātou tikanga te whakakapi i ngā tikanga whakaputa o nāianei mā te tirotiro i tōna pānga ki te taiao me te whai huatanga ohaoha.
"I runga i ngā hua, ka taea e mātou te kī he huarahi pai ki te taiao tā mātou tikanga hei whakakapi i te hurihanga o te hauhā waro, ka taea te whakakapi i ngā tikanga tuku iho, me te āwhina ki te whakaiti i ngā tukunga hauhā ahumahi," te kī a Yun.
I kī te kaipūtaiao ahakoa te ahua pai o te hurihanga o te hauhā waro hei hua whai hua, ehara i te mea ngāwari te whakanui ake i ēnei tukanga. Kāore anō kia hokohokohia te nuinga o ngā hangarau CCU nā te mea he iti te whaihua o ō rātou āhuatanga ōhanga ki te whakatauritea ki ngā tukanga arumoni matua.
"Me whakakotahi tātou i te tukanga CCU me te hangarua para kia whai hua ai mō te taiao me te ōhanga. Tērā pea ka āwhina tēnei ki te whakatutuki i ngā whāinga tukunga kore-kore ā muri ake nei," te kī a Lee.
