Wāhanga Tuarua: Te Hurihanga Wai—Ngā Ester Taiao

Neke atu i te rau tau te roa o te whakamahinga o te hinu kohuke hei whakamatao me te whakamatao i ngā whakawhiti hiko wai. He whai hua, he mārama, he ohanga hoki—engari he ngoikoretanga anō hoki. Ka pōturi te pirau o te hinu kohuke i te nuinga o te wā, ā, he mōrearea ahi me tōna ira mura iti (160-180°C te tikanga), ā, ka taea te whakararu i te taiao mō te wā roa mēnā ka turuturu.

He huarahi kē atu whai hua ngā wai ester tūturu—i ahu mai i ngā hinu huawhenua pērā i te pīni soya, te rapeseed rānei.

Hototahitanga Taiao.He ngāwari te pirau o ngā ester taiao, ā, ka eke ki te 95 ōrau, neke atu rānei, i roto i ngā wiki i raro i ngā tikanga whakamātautau paerewa. Nā tēnei ka tino pai mō ngā wāhi tairongo taiao—e tata ana ki ngā awa, i ngā wāhi taiao tiakina, i roto rānei i ngā tāone nui kei reira he iti noa ngā hanganga aukati. Mēnā ka turuturu, ka tino whakaitihia te pānga ki te taiao ki te whakataurite ki te hinu kohuke.

Te Haumaru Ahi.He rite tonu te hiranga o ngā painga haumaru o ngā ester tūturu. Mēnā he nui ake ngā pūmahana mura i te 300°C—he maha ngā wā ka eke ki te 350°C, neke atu rānei—ka tino whakaitihia e ēnei wai te mōrearea ahi. Ko ētahi o ngā hanganga he āhuatanga tinei-ake, e whakarato ana i tētahi atu paparanga tiaki. Mō ngā whakaurunga o roto, mō ngā wāhi taupori kikī rānei, mā tēnei āhuatanga anake ka taea te whakamana i te kōwhiringa o ngā whakawhiti hiko tūturu kua whakakīia ki te ester.

Te Mahi Hangarau.Haunga ngā painga haumaru me te taiao, he pai ngā painga hangarau o ngā ester taiao. Mā te kaha ake o te wai e ātete ki te makuku ka roa ake te ora o te whakamahana, nā te mea ka puhoi ake te pirau o te pepa cellulose kua whakakiia ki te ester taiao i te hinu kohuke i raro i ngā āhuatanga rite. He tino pai hoki te pumau o te waikura o ngā ester taiao ina tika te hanga, ka taea ai te roa ake o ngā wā mahi.

Whakamanatanga o te Ao Tūturu.Kāore te hangarau e whakamātautauhia ana. E ai ki ngā tuhinga ahumahi, neke atu i te rua miriona ngā whakawhiti hiko ester taiao kei te whakamahia puta noa i te ao. Kua piki haere tonu ngā taumata ngaohiko i te mea e tipu haere ana te whakapono—nō nā tata nei i whiwhi a Hitachi Energy i te tiwhikete hangarau mō te whakawhiti hiko ester taiao 765 kV, 250 MVA, te waeine ngaohiko teitei rawa atu o tōna momo. I Āhia, kua angitu te kaweake a ngā kaihanga i ngā whakawhiti hiko whakarewa kore-āhua kua whakakiia ki te ester taiao ki Hapani, kei reira rātou e mahi ana i roto i te whatunga hiko.

Wāhanga Tuatoru: Te Pakari Matua—Te Metara Kore-āhua

Ahakoa e aro ana ngā ester taiao ki ngā āhuatanga taiao me te haumaru o te mahi whakawhiti hiko, ka aro atu ngā matua konganuku kore-āhua ki te wero matua o te whai huatanga o te pūngao.

Te Pūtaiao Rauemi.Ko ngā matua whakawhiti hiko tuku iho he mea hanga mai i te maitai silicon e anga ana ki te witi, he rauemi tioata he hanganga ngota kua whakaritea. Ka puta te konganuku kore-ahua mā te whakamatao tere i te koranu rewa—i ngā tere e tata ana ki te kotahi miriona nekehanga ia hekona—kia kore ai e puta he tioata. Ka mau tonu te whakaritenga ngota matapōkere o te āhua wai i te totoka ka puta.

He pānga nui tō tēnei hanganga koretake ki te whanonga aukume. I roto i ngā rauemi tioata, me hangai ngā rohe aukume ki ngā ahunga tioata motuhake, me whakauru te pūngao ki ia huringa iahiko tauutuutu. I roto i te konganuku kore-āhua, mā te kore o te raupapa tioata ka taea e ngā rohe te urupare noa atu ki ngā āpure aukume e huri haere ana. Ko te mutunga mai he whakahekenga nui o te ngaronga hysteresis—te pūngao e memeha ana i ia wā ka aukumetia te matua, ka tangohia te aukume.

Ngā Hua Ka Taea te Ine.He nui te whakapainga o te mahi. Ka whakaitihia e ngā matua konganuku kore-ahua ngā ngaronga kore-kawenga mā te 70 ki te 80 ōrau ki te whakataurite ki te maitai anga-kiko noa. Mō te 1,000 kVA noa Whakawhiti Tohatoha, ko te tikanga o tēnei he penapena pūngao ā-tau neke atu i te 6,000 kWh. I roto i te 30 tau te roa o te ora ratonga, ka taea e te whakahekenga tāpiri o ngā tukunga CO₂ te eke ki te 4,400 tana mō ia whakawhiti hiko.

Ngā Whakaaro mō te Tono.Kāore e kore he taupatupatu mō ngā whakawhiti hiko konganuku kore-ahua. He nui ake te utu o te rauemi i te maitai tuku iho, ā, me rerekē ngā hoahoa matua o ōna āhuatanga aukume. Tērā pea he nui ake, he taumaha ake hoki ngā whakawhiti hiko mō tētahi whakatauranga kua whakaritea, ka raru pea te tāutanga ki ngā wāhi iti te wāhi. Heoi, mō ngā tono e nui ana ngā mate kore-kawenga—pērā i ngā whakawhiti hiko tohatoha e iti ana te utaina i te nuinga o te wā—he mārama te painga utu huringa ora.

E whakaū ana ngā tātaritanga ōhanga ahakoa te nui ake o te utu tīmatanga, he iti ake te utu katoa o te mana o ngā whakawhiti hiko whakarewa kore-āhua ina tika te aromatawai i ngā mate. He pono rawa tēnei i ngā mākete he nui ngā utu hiko, he kaha rānei ngā paerewa whai hua.

Wāhanga Tuawhā: Te Huarahi Whakakotahi—Te Mahi Tahi i roto i te Hoahoa

Ka whakakotahihia e ngā whakawhiti hiko matomato tino matatau ngā auahatanga e rua: te whakamarumaru ester taiao me ngā matua konganuku kore-āhua. Ka arohia e tēnei huarahi takirua ngā pānga taiao mai i ngā koki katoa.

He Tauira o te Ao Tūturu.I whakaatuhia e te tauira whakawhiti hiko matomato i hangaia me ngā matua whakarewa kore-āhua me te hinu ester taiao te iti o ngā mate, me te tutuki i ngā paerewa hangarau katoa e tika ana. I kitea te whai huatanga hangarau me te ataahua o te ōhanga o te whakakotahitanga i te aromatawai i runga i te utu katoa o te mana.

Kei tua atu i te Matua me te Wai.Ko ētahi atu auahatanga hei tautoko i ēnei hangarau matua. Ko te maitai silicon tino angiangi - tae atu ki te 0.20 mm te matotoru - ka pai ake te mahi me te pupuri tonu i ngā tukanga hanga kua mōhiotia. Mō ngā tono kāore e whai hua te whakamarumaru wai, Whakawhiti Momo-MarokeKo ngā takai hiko epoxy he mea haumaru ki te ahi, kāore hoki e turuturu. Ā, mō ngā taumata ngaohiko teitei rawa atu, kei te haere tonu ngā rangahau ki ngā pūnaha whakamarumaru hototahi ki te ester ki te pana i ngā rohe o ngā mea ka taea.

Ngā Huarahi Kōwhiri e Puta Ake Ana.Mō ngā tono motuhake, ko ngā whakawhiti hiko hau-whakamarumaru e whakamahi ana i ngā ranunga C₄F₇N/CO₂ ka tuku i tētahi atu ara ki te whakaiti i te pānga ki te taiao, me te whakakotahi i te kore-mura me te iti ake o te pūmanawa whakamahana ā-ao i ngā waeine SF₆ tuku iho.

Wāhanga Tuarima: Tirohanga Mākete me ngā Ārahi Whakamahinga

Kei te tere haere te whakawhiti ki ngā whakawhiti matomato, e peia ana e ngā kaha maha.

Te Pēhanga Whakahaere.Kei te kaha haere ngā paerewa whai hua puta noa i te ao. Ko te paerewa o Haina, arā, ko te GB 20052-2020, ko ngā ture hoahoa taiao a te EU, me ngā anga rite i roto i ētahi atu mākete e whakahau ana i ngā taumata whai hua teitei ake e pai ake ai te konganuku kore-āhua me ētahi atu rauemi matua matatau. Kei te piki haere te here o ngā ture haumaru ahi i ngā whakaurunga hinu kohuke i ngā wāhi taupori, e whakanui ana i te hiahia mō ngā momo ester taiao.

Ngā Whāinga Whakapūmautanga o te Kamupene.Kei te piki haere te pēhanga ki ngā kamupene hiko me ngā kaihoko ahumahi nui kia whakaitihia ō rātou tapuwae waro. He huarahi tūturu ngā whakawhiti hiko matomato hei whakaatu i te whakapau kaha ki te taiao, me te whakaiti hoki i ngā utu whakahaere. Inaianei, me whai Whakapuakitanga Hua Taiao, tiwhikete tapuwae waro rānei ētahi kaihoko hei wāhanga o ngā whakaritenga hoko.

Te Whakataetae Utu.I te pikinga ake o ngā rahinga whakaputa me te nui haere o ngā wheako hanga, kei te heke te utu mō ngā whakawhiti hiko matomato. Mō ngā tono maha, ko te painga utu o te huringa ora inaianei e pai ake ana ki ngā kōwhiringa matomato ahakoa kāore e whakaarohia ngā painga taiao.

Whakamutunga: He Ara Mārama ki Mua

He mārama te whakautu ki te pātai "Ka taea e ngā taputapu whakawhiti hiko te huri hei matomato tūturu?": kua pērā kē rātou, ā, kei te whakapai tonu te hangarau.

Ka whakakorea e ngā wai ester taiao ngā āwangawanga mō te haumaru taiao me te ahi e pā ana ki te hinu kohuke, me te tuku i te mahi hangarau rite, pai ake rānei. Ka whakaitihia e ngā matua konganuku kore-kawenga ngā mate kore-kawenga mā te 70 ki te 80 ōrau, ka tukuna he penapena pūngao nui i roto i ngā tekau tau o te mahi. Mā te whakakotahitanga, ka tautuhia e ēnei hangarau he whakatupuranga hou o ngā whakawhiti hiko he haumaru ake, he ma ake, he pai ake hoki i ngā mea katoa i mua.

Mō ngā tohunga hokohoko me ngā kaiwhakawhanake kaupapa, he māmā noa iho ngā pānga. Kāore ngā whakawhiti hiko matomato i te waiho hei hua motuhake, hei tauira whakamātautau rānei. Kei te wātea mai i te taha hokohoko, kua whakamātauhia i runga i te hangarau, ā, kei te piki haere te utu whakataetae. Ko te tohu i ēnei i tēnei rā ko te tikanga he iti ake ngā utu whakahaere, he iti ake te mōrearea taiao, me te hangai ki te pana o te ao ki tētahi heke mai pūngao pumau ake.

Kua kiia te whakawhiti hiko ko te hoiho mahi o te whatunga hiko. Nā ēnei auahatanga, kua huri hei mea nui ake: he kaiāwhina matua ki te whakawhiti pūngao ma.
