I roto i te tukanga tiaki taiao o te whakaputanga ahumahi, ko te tango-pūngoi he taahiraa matua ki te tiaki i te ma o te hau, ā, ko te pūngoi, hei "kaiwhakahaere matua" o te pūnaha tango-pūngoi, ka whakatau tika i te whai huatanga o te tango-pūngoi me te roa o te ora o ngā taputapu i runga i tana mahi. I roto i ngā rauemi pūngoi maha,kāpira silicon (SiC)Kua āta noho hei rauemi pai rawa atu i roto i te mara o te desulfurization ahumahi nā ōna painga mahi ahurei, ā, kua riro hei kaiawhina kaha mō ngā umanga ki te whakatutuki i te tino pai me te tiaki taiao.
He tokomaha pea kāore i te mōhio ki te silicon carbide. He māmā noa iho, he rauemi kore-whakarewa kore-waro i hangaia i roto i te ao tūroa, e whakakotahi ana i te ātete pāmahana teitei o ngā uku me ngā āhuatanga kaha teitei o ngā konganuku, pērā i te "toa pakari" i hangaia mō ngā taiao ahumahi uaua. Ka whakamahia katoatia e te pūwero whakakore-whana i hangaia ki te silicon carbide ngā painga o tēnei rauemi.
Tuatahi, ko te ātete kaha ki te waikura te tino kaupapa o ngā pūwero whakakorenga whanariki silicon carbide. I roto i te tukanga whakakorenga whanariki ahumahi, ko ngā whakakorenga whanariki he mea tino waikura, he kaha te waikawa me te kawakore. Ka ngawari te rumakina o ngā pūwero whakarewa noa ki roto mō te wā roa, ka arahi pea ki te waikura me te turuturu. Ehara i te mea ka pā noa tēnei ki te pānga whakakorenga whanariki, engari me whakakapi pinepine hoki, ka piki ake te utu o te umanga. He tino pai te pumau matū o te rauemi silicon carbide, ā, ka taea te ātete ki te waikura o ngā waikawa kaha me ngā kawakore. Ahakoa i roto i ngā taiao waikura pāmahana teitei mō te wā roa, ka taea e ia te pupuri i te hanganga tika, ka roa ake te ora o ngā pūwero me te whakaiti i te auau tiaki taputapu.
Tuarua, nā tōna ātete tino pai ki te pāmahana teitei, he pai mō ngā āhuatanga mahi uaua. Ko te pāmahana o te hau para i tukuna mai i ngā kohua ahumahi, ngā oumu me ētahi atu taputapu he teitei te nuinga o te wā, ā, ko ngā pūwero i hangaia mai i ngā rauemi noa ka ngāwari ki te huri me te tawhito i raro i te taiao pāmahana teitei, ka hua ake he pānga rehu ngoikore me te whakaiti i te pai o te tango whanariki. He tino pai te ātete pāmahana teitei o te silicone carbide. Ka taea te mahi pumau i roto i te hau para pāmahana teitei o ngā rau nekehanga Celsius, ā, kāore e pā ki te hanganga me te mahi nā ngā huringa pāmahana, kia whakarite kia ōrite, kia ngawari hoki te rehu, kia taea ai e te desulfurizer te pa atu ki te hau para me te whakapai ake i te pai o te tango whanariki.
Hei tāpiritanga, kaua e whakaititia te ātete kakahu o te rauemi silicon carbide. Ina whakahaerehia te pūnaha desulfurization, tera pea he iti noa ngā matūriki totoka kei roto i te desulfurizer, ka puta he kakahu tonu ki te pakitara o roto o te nozzle. I muri i te whakamahinga roa o te nozzle noa, ka nui ake te whakatuwheratanga, ā, ka koretake te rehu. He tino teitei te pakeke o te silicon carbide, ā, he nui ake tōna ātete kakahu i ērā o ngā konganuku me ngā uku noa. Ka taea e ia te ātete pai ki te horo me te kakahu o ngā matūriki totoka, te pupuri i te pumau o te whakatuwheratanga o te nozzle, te whakarite i te pumau roa o te pānga rehu, me te karo i te whakahekenga o te pai o te desulfurization i puta mai i te kakahu o te nozzle.
I roto i ngā whakaritenga taiao e tino kaha haere ana, ehara i te mea me whakatutuki noa ngā umanga i ngā tukunga paerewa, engari me whai hoki i te whakahaere pai, pumau, me te iti o te utu mō ngā taputapu tiaki taiao. Ko te pūwero whakakorenga hauota silicon carbide, me ōna painga matua e toru o te ātete ki te waikura, te ātete ki te pāmahana teitei, me te ātete ki te kakahu, ka urutau pai ki ngā whakaritenga uaua o te whakakorenga hauota ahumahi. Ka taea e ia te whakapai ake i te pumau o te pūnaha whakakorenga hauota me te whakaiti i ngā utu tiaki taputapu, ka noho hei whiringa kounga teitei mō ngā whakapainga taiao umanga.
I ngā rā kei te heke mai, me te whanaketanga tonu o te hangarau whakarite rauemi silicon carbide, ka whānui ake tōna whakamahinga i roto i te mara o te tiaki taiao ahumahi. Ā, ka āwhina tonu te pūwero whakakorenga hauota silicon carbide i ngā umanga ki te whakatutuki i te whakaputa matomato me tōna mahi pakari, ka nui ake te whai wāhi ki te tiaki i te rangi kikorangi me ngā kapua mā.
