He paheke tango hauhā hei tango i te hauhā mai i te hau māori

I tēnei wā, ko ngā tukanga mō te tango i te hau māori ko te tikanga cryogenic, te tikanga adsorption, te tikanga wehenga membrane, te whakakotahitanga rānei o ngā tikanga e rua, e toru rānei. Ka taea e te parakore o te hua o te helium mō te reti tango helium te tutuki i te 99.9999%.

(1) Tikanga cryogenic

Ko te whakatōtōtanga cryogenic tētahi tikanga e whakamahia whānuitia ana i roto i te nuinga o ngā tipu whakaora hau māori reo-rahi ki te rahi. Ko te kaupapa matua ko te whakamahi i te hauota wai hei whakamatao (tata ki te -190 ℃) hei whakakōpikopiko haere i ngā warowaihā me ētahi atu wāhanga i roto i te hau māori. Nā te tino iti o te pāmahana koropupū o te helium, ka wehea i te mutunga mai i ētahi atu wāhanga o te hau māori. He tikanga noa tēnei i roto i te tukanga tango helium.

(2) Tikanga Whakauru Pēhanga

Ko te tukanga mimiti pēhanga (PSA) e whakamahi ana i ngā momo mimiti rerekē hei mimiti i ngā wāhanga ehara i te heriuma i roto i te hau māori, ā, mā reira ka wehea ngā hua heriuma. I te nuinga o te wā, ko ngā pourewa mimiti PSA he moenga wehewehe o ngā rauemi mimiti rerekē hei whakahaere i ngā wāhanga rerekē o te hau māori, pērā i te silica gel, i ngā moenga alumina rānei hei tango i te wai, ngā moenga waro whakahohe hei tango i te hauhā, ngā moenga zeolite hei tango i te methane me te hauota, me ētahi atu. I muri i te whakakīkītanga o te mimiti i te hau poke, ka taea te whakamahi i ngā tikanga pērā i te whakaheke pēhanga, te papu korehau rānei hei tango i te hau poke me te whakahoki mai i te mahi a te mimiti.

(3) Tikanga Wehenga Kiriuhi

He hangarau wehewehe hou te kiriuhi wehenga hau. Ka whakawhitihia ngā wāhanga hau ki runga i ngā kiriata polymer (pērā i ngā muka acetate, polypropylene, poly-sulfone, polyimide, me ētahi atu) i runga i te kaupapa o te horapa whakarewa. Ka tutuki te wehenga o ia wāhanga i runga i ngā rerekētanga o te wairewa me te tere horapa o ngā wāhanga hau rerekē i roto i te rauemi kiriuhi. Ina haere ngā ranunga hau e rua, neke atu rānei, i roto i te kiriata polymer, he nui ake te tere uruhanga o ngā wāhanga pērā i te herium me te hauwai i tērā o te hauota, te methane, me ētahi atu warowaihā.

Kāore e taea te whakaputa i te hīriama i roto i te ahumahi, ka taea anake te pure. I roto i ngā whakamātautau ahupūngao, ka taea te whiwhi mā te pirau ngota, engari he iti noa iho ngā rahinga. I roto i te ariā, ka taea te tango mai i te rangi, engari nā te iti o te ihirangi hīriama i roto i te rangi, ka taea te tiki i te hīriama mai i te hau maori kei roto tata ki te 0.5% te hīriama i roto i te ahumahi mā te wehenga, te whakamahine, me te purenga o ngā taputapu tango hīriama.
