Waqtigan xaadirka ah, hababka loo soo saaro helium-ka gaaska dabiiciga ah gudaha iyo dibaddaba waxaa ugu badan habka cryogenic, habka nuugista, habka kala soocida xuubka, ama isku-darka laba ama saddex hab oo wadajir loo isticmaalo.
1) Habka qaboojinta qoto dheer
Sifeynta qabowga qoto dheer waa hab caadi ah oo loo isticmaalo inta badan warshadda helium-ka soo kabashada gaaska dabiiciga ah ee dhexdhexaadka ah ilaa kuwa waaweyn. Mabda'a ayaa ah in loo isticmaalo nitrogen dareere ah qaboojiyaha (qiyaastii -190 ℃) si tartiib tartiib ah isku qas hydrocarbons iyo qaybaha kale ee gaaska dabiiciga ah, iyo sababtoo ah barta karkarinta ee helium-ka oo aad u hooseysa, ugu dambeyntii waxay ka go'daa qaybaha kale ee gaaska dabiiciga ah.
2) Habka nuugista cadaadiska
The habka nuugista cadaadiska lulid (PSA) Wuxuu adeegsadaa dareereyaal kala duwan si uu u nuugo qaybaha gaaska dabiiciga ah marka laga reebo helium, taasoo kala soocda alaabada helium. Guud ahaan, munaaradaha nuugista PSA waxaa ka buuxa sariiro kala soocid ah oo ka kooban walxo nuugid kala duwan si ay ula qabsadaan qaybaha kala duwan ee gaaska dabiiciga ah, sida jelka silica ama sariiraha alumina si looga saaro biyaha, sariiraha kaarboonka ee firfircoon si looga saaro kaarboon laba ogsaydh, sariiraha zeolite ee methane iyo ka saarista nitrogen, iwm. Ka dib marka nuugista ay buuxiso gaaska wasakhda ah, hababka sida dib u soo celinta cadaadiska ama bamgareynta faakiyuumka ayaa loo isticmaali karaa in lagu xalliyo gaaska wasakhda ah, taasoo dib u soo celinaysa dhaqdhaqaaqa nuugista.
3) Habka kala soocidda xuubka
Xuubka kala-soocidda gaaska waa tiknoolajiyad cusub oo kala-soocid ah. Qaybaha gaaska waxay ku wareejiyaan cufnaanta filimada polymer-ka (sida fiilooyinka acetate, polypropylene, polysulfone, polyimide, iwm.) iyadoo lagu saleynayo mabda'a kala-soocidda kala-soocidda. Kala-soocidda qayb kasta waxaa lagu gaaraa iyadoo la kala beddelayo heerka milmida iyo faafinta qaybaha gaaska ee kala duwan ee ku jira walxaha xuubka. Marka isku-darka laba ama in ka badan oo gaas ah uu dhex maro filim polymer ah, heerka daloolinta qaybaha sida helium iyo hydrogen aad ayuu uga sarreeyaa kan nitrogen, methane, iyo hydrocarbons kale.
