I kēia manawa, ʻo nā kaʻina hana no ka unuhi ʻana i ka helium mai ke kinoea kūlohelohe ma ka home a ma waho e komo pū ana me ke ʻano cryogenic, ke ʻano adsorption, ke ʻano hoʻokaʻawale membrane, a i ʻole ka hui pū ʻana o ʻelua a ʻekolu mau kaʻina hana i hoʻohana pū ʻia.
1) Ke ʻano hoʻoluʻu hohonu
ʻO ka hoʻoheheʻe anuanu hohonu kahi ʻano hana i hoʻohana pinepine ʻia ma ka hapa nui o nā mea kanu helium hoʻōla kinoea kūlohelohe waena a nui. ʻO ke kumumanaʻo ka hoʻohana ʻana i ka naikokene wai ma ke ʻano he refrigerant (ma kahi o -190 ℃) e hoʻomaʻamaʻa mālie. hoʻohuihui i nā hydrocarbons a me nā ʻāpana ʻē aʻe i loko o ke kinoea kūlohelohe, a ma muli o ke kiko paila haʻahaʻa loa o ka helium, hoʻokaʻawale hope loa ia mai nā ʻāpana ʻē aʻe i loko o ke kinoea kūlohelohe.
2) Ke ʻano hana adsorption swing pressure
ʻO ka ke kaʻina hana adsorption swing pressure (PSA) Hoʻohana nā adsorbents like ʻole e adsorb i nā ʻāpana o ke kinoea kūlohelohe ʻē aʻe ma mua o ka helium, a laila e hoʻokaʻawale ana i nā huahana helium. Ma keʻano laulā, ua piha nā hale kiaʻi adsorption PSA me nā moena hoʻokaʻawale o nā mea adsorption like ʻole e hoʻoponopono i nā ʻāpana like ʻole i loko o ke kinoea kūlohelohe, e like me ka silica gel a i ʻole nā moena alumina no ka wehe ʻana i ka wai, nā moena kalapona i hoʻāla ʻia no ka wehe ʻana i ke kalapona dioxide, nā moena zeolite no ka wehe ʻana i ka methane a me ka nitrogen, a pēlā aku. Ma hope o ka hoʻopiha ʻana o ka adsorbent i ke kinoea haumia, hiki ke hoʻohana ʻia nā ʻano hana e like me ka depressurization backflushing a i ʻole ka vacuum pumping e hoʻonā i ke kinoea haumia, a laila e hoʻihoʻi i ka hana o ka adsorbent.
3) Ke ʻano hoʻokaʻawale membrane
He ʻenehana hoʻokaʻawale hou ka membrane hoʻokaʻawale kinoea. Hoʻoili nā ʻāpana kinoea i ka nui ma nā kiʻiʻoniʻoni polymer (e like me nā olonā acetate, polypropylene, polysulfone, polyimide, a pēlā aku) ma muli o ke kumumanaʻo o ka hoʻolaha hoʻoheheʻe ʻana. Hoʻokō ʻia ka hoʻokaʻawale ʻana o kēlā me kēia ʻāpana ma ka hoʻololi ʻana i ka solubility a me ka diffusion rate o nā ʻāpana kinoea like ʻole i loko o ka mea membrane. Ke hele kahi hui ʻana o ʻelua a ʻoi aku paha nā kinoea ma o kahi kiʻiʻoniʻoni polymer, ʻoi aku ka kiʻekiʻe o ka permeation rate o nā ʻāpana e like me ka helium a me ka hydrogen ma mua o ka nitrogen, methane, a me nā hydrocarbons ʻē aʻe.
