Shabaq soo saarista helium si looga soo saaro helium gaaska dabiiciga ah

Waqtigan xaadirka ah, hababka loo soo saaro helium-ka gaaska dabiiciga ah waxaa ugu horreyn ka mid ah habka cryogenic, habka nuugista, habka kala soocidda xuubka, ama isku-darka laba ama saddex ka mid ah saddexda hab. Nadiifnimada helium-ka ee badeecadaha loogu talagalay xoqidda Helium-ka waxay la kulmi kartaa 99.9999%

(1) Habka Cryogenic

Kala-soocidda Cryogenic waa hab caadi ah oo loo isticmaalo inta badan dhirta helium-ka dabiiciga ah ee dhexdhexaadka ah ilaa kuwa waaweyn. Mabda'a ayaa ah in la isticmaalo nitrogen dareere ah sida qaboojiyaha (qiyaastii -190 ℃) si tartiib tartiib ah loogu ururiyo hydrocarbons-ka iyo qaybaha kale ee gaaska dabiiciga ah. Sababtoo ah barta karkarinta ee helium-ka oo aad u hooseysa, ugu dambeyntii waxaa laga soocaa qaybaha kale ee gaaska dabiiciga ah. Tani waa hab caadi ah oo lagu sameeyo habka soo saarista helium-ka.

(2) Habka nuugista cadaadiska ee cadaadiska

Habka nuugista cadaadiska (PSA) wuxuu adeegsadaa nuugayaal kala duwan si uu u nuugo qaybaha aan ahayn helium ee gaaska dabiiciga ah, taasoo kala soocda alaabada helium. Guud ahaan, munaaradaha nuugista PSA waxay ku qalabaysan yihiin sariiro kala soocid ah oo ka kooban walxo nuugid kala duwan si ay ula macaamilaan 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 si looga saaro methane iyo nitrogen, iwm. Ka dib marka nuugista ay buuxiso gaaska wasakhda ah, hababka sida buufinta cadaadiska ama bamgareynta faakiyuumka ayaa loo isticmaali karaa in laga saaro gaaska wasakhda ah loona soo celiyo dhaqdhaqaaqa nuugista.

(3) Habka Kala Soocida Xuubka

Xuubka kala-soocidda gaaska waa tiknoolajiyad cusub oo kala-soocid ah. Qaybaha gaaska waxaa lagu wareejiyaa tiro badan filimada polymer-ka (sida fiilooyinka acetate, polypropylene, poly-sulfone, polyimide, iwm.) iyadoo lagu saleynayo mabda'a kala-soocidda kala-soocidda. Kala-soocidda qayb kasta waxaa lagu gaaraa iyadoo loo eegayo heerarka kala duwan ee milmida iyo kala-soocidda ee qaybaha gaaska ee kala duwan ee ku jira walxaha xuubka. Marka laba ama in ka badan oo isku-darka gaaska ay dhex maraan filim polymer ah, heerka kala-soocidda ee qaybaha sida helium iyo hydrogen aad ayuu uga sarreeyaa kan nitrogen, methane, iyo hydrocarbons kale.

Helium laguma soo saari karo warshadaha, waxaa la nadiifin karaa oo keliya. Tijaabooyinka fiisikiska, waxaa laga heli karaa iyada oo loo marayo qudhun atomi ah, laakiin tiro aad u yar. Aragti ahaan, waxaa laga soo saari karaa hawada, laakiin sababtoo ah heerka helium ee hawada ku yar, helium waxaa laga heli karaa gaaska dabiiciga ah oo ka kooban qiyaastii 0.5% helium warshadaha iyada oo loo marayo kala soocidda, sifeynta, iyo nadiifinta aaladaha soo saarista helium.
