Me pēhea te whiriwhiri i tētahi kaihanga hauota e tika ana

I mua i te whakatau i ngā whakatakotoranga tauira motuhake (arā, Te Whakaputa Hauota ia hāora, te parakore o te hauota, te pēhanga putanga, te ira tomairangi), me arotahi tātou ki tētahi tātaritanga whakatairite whānui o te mahi me ngā āhuatanga o tekaihanga hauota, ā, ka whakatau i te kōwhiringa tika i runga i ngā āhuatanga o tō tātou taiao o nāianei.

Ngā whakaritenga mō te hauota i roto i ngā ahumahi rerekē

A, Ngā ahumahi whakarewa me te tukatuka whakarewa

Ko ētahi o ēnei ahumahi e hiahia ana ki te hauota he nui ake i te 99.5% te parakore, ko ētahi ia e hiahia ana ki te hauota kounga teitei he nui ake i te 99.9995% te parakore me te ira tomairangi i raro iho i te -65°C. Me whakatau tēnei i runga i ngā tikanga whakaputa a te kiritaki.

B, Ngā ahumahi matū me ngā rauemi hou

Ko te tikanga, kāore i te teitei ngā whakaritenga mō te parakore o te hauota, ā, he maha ngā parakore neke atu i te 98% ka taea te whakamahi. Heoi, ko ngā whakaritenga tuturu e whakawhirinaki ana ki te tukanga whakaputa a te kiritaki.

C, Ngā ahumahi kai me te rongoā

Kāore i te nui ngā whakaritenga mō te hauota i te nuinga o ngā ahumahi kai, ā, ka taea e te parakore 99.5%~99.9% te whakatutuki i ngā whakaritenga. He iti noa ngā ahumahi kai me whiriwhiri i te parakore 99.99% nā runga i ngā whakaritenga tukatuka. Ko te tikanga, me whiwhi te ahumahi rongoā i te parakore hauota o te 99.99%, ā, me hanga ki te kowiri tira.

ahumahi hikohiko d

Ko te tikanga, he teitei rawa ngā whakaritenga mō te hauota, ā, ko te tikanga me eke te parakore o te hauota ki te 99.99%, neke atu rānei.

Te whakataurite i waenga i ngā momo Pūkaha Hauotangā

A, Kaihanga hauota wehenga hau Cryogenic

Ko te whakaputa hauota wehenga hau kōkō he tikanga whakaputa hauota tuku iho, kua tata ki te tekau tau te roa o te hītori. Ka whakamahia te hau hei rauemi mata, ka pēhi, ka purea, kātahi ka whakamahi i te whakawhiti wera hei whakawai i te hau hei hau wai. Ko te hau wai he ranunga o te hāora wai me te hauota wai. Ko ngā pāmahana kohua rerekē o te hāora wai me te hauota wai (i te 1 hau, ko te pāmahana kohua o te mea tuatahi ko -183℃ me te mea tuarua ko -196℃) ka whakamahia hei wehewehe i a rātou mā te whakatōtō i te hau wai hei whiwhi hauota. He uaua ngā taputapu whakaputa hauota wehenga hau kōkō, he nui te wāhi e nohoia ana, he nui ngā utu hanganga, me nui ake te haumi kotahi ki ngā taputapu, he nui ngā utu whakahaere, he puhoi te whakaputa hau (12 ki te 24 hāora), he nui ngā whakaritenga tāutanga, me te huringa roa. I runga i ngā āhuatanga o ngā taputapu, te tāutanga me te hanganga, ko te tauine haumi o ngā taputapu PSA me ngā whakatakotoranga rite i raro i te 3500Nm3/h he 20% ki te 50% te iti iho i te tauine haumi o ngā taputapu PSA me ngā whakatakotoranga rite i raro i te 3500Nm3/h. He pai ngā taputapu whakaputa hauota wehenga hau cryogenic mō te whakaputa hauota ahumahi tauine nui, ko te whakaputa hauota waenga me te tauine iti kāore i te ohanga.

B, PSA pēhanga piu whakaputa hauota adsorption

Ko te tikanga o te whakamahi i te hau hei rauemi mata, te tātari waro hei adsorbent, te whakamahi i te kaupapa o te adsorption swing pressure, me te whakamahi i te adsorption whiriwhiri o te hāora me te hauota mā te tātari waro hei wehe i te hauota me te hāora e kiia ana ko te tikanga. Te whakaputanga hauota PSAHe hangarau whakaputa hauota hou tēnei i tere te whanaketanga i ngā tau 1970. Ki te whakatauritea ki ngā tikanga whakaputa hauota tuku iho, he ngāwari te rere o te tukanga, he aunoatanga teitei, he tere te whakaputa hau (15-30 meneti), he iti te whakapaunga pūngao, ka taea te whakarerekē i te parakore o te hua i roto i te whānuitanga nui kia rite ki ngā hiahia o te kaiwhakamahi, he watea te whakahaere me te tiaki, he iti te utu whakahaere, he kaha te urutau ki ngā taputapu, me ētahi atu. Nō reira, he tino whakataetae i roto i ngā taputapu whakaputa hauota i raro i te 1000Nm3/h, ā, e tino manakohia ana e ngā kaiwhakamahi hauota reo me te iti. Psa Hauota kua waiho te whakaputa hei tikanga mā ngā kaiwhakamahi hauota waenga me te iti.

C, Kaihanga hauota wehenga kiriuhi

Mā te whakamahi i te hau hei rauemi mata, i raro i ētahi āhuatanga pēhanga, ka wehea te hāora me te hauota mā te whakamahi i ngā tere urunga rerekē o ngā hau me ngā āhuatanga rerekē pērā i te hāora me te hauota i roto i te kiriuhi. Ki te whakatauritea ki ētahi atu taputapu whakaputa hauota, he pai ake te hanganga, he iti ake te rahi, kāore he takirere whakawhiti, he iti ake te tiaki, he tere ake te whakaputa hau (≤3 meneti), me te whakawhānui i te kaha. He tino pai mō ngā kaiwhakamahi hauota reo-rahi me te iti me te parakore hauota ≤98%, ā, ko ia te ōwehenga mahi-utu pai rawa atu. Ina neke ake te parakore hauota i te 98%, he nui ake te utu i te 15% i te utu o ngā kaihanga hauota PSA o ngā whakaritenga ōrite.

Ngā āhuatanga e pā ana ki te utu o ngā kaihanga hauota

1. Te utu hoko kotahi mō te pūnaha katoa. I tēnei wā, he maha ngā waitohu kei te mākete, ā, he rite te kounga ki te utu.

2. Te pumau o te mahi a ngā taputapu me te roanga o te ora ratonga e whakatauhia ana.

3. Ngā utu whakahaere me te tiaki ā-tau.

4. Ngā utu wai me te hiko o ia rā.
