ukusebenza kwezitshalo somhlangano wokuhluhluza amagase
I-PSA (Pressure Swing Adsorption) yomthetho wokuhluhluza amaxhobo angaphakathi kwezihlaba ezintathu zokuthiwa ngokupheleleyo ukususa amaxhobo amahlu kwesikhatsi esisodwa sikhona ngokusebenzisa umthetho omncane womthetho weziqhopho. Lesi sicelo sihlola ngokusebenzisa izilungiselelo eziphakeme zezinhlanga leziqhopho eziziphumuleka ukulayisha i-nitrogen ngelixa lwe-oxygen liqhubekise. Umthetho wenkqubo uluhlola amaqanda ababili: ukubuyiselwa nokubuyiswa. Ngoku buyiselwa, umoya ombuyiselwe uhlalele kwi-zilungiselelo zeziqhopho, apho amaqanda ka-nitrogen azithatheliswa, lokhu kuxhasa ukuthi amaxhobo amahlu akufuneki. Ngoku buyiswa, i-nitrogen elibuyiselwe edlule kumkhathazana, ukususa izilungiselelo ezifuneki kukhiqiza yesikhwama esilandelayo. Lolu hlobo lokubuyiswa lokungaphambili kuhlinzekelela ukusuka komthetho wamaxhobo amahlu ngenxa yokuba imigomo yezimpawu ziyahlukile kusukela kwe-93% kunye ne-95%. Iphrojekthi ingamashumi amabini amanye amacomponekthi amahlukeneyo phakathi komphendulo womoya, amasisthemu amaphambili, amatowulu amaphumeleleyo weziqhopho, amaphendulo komaxhobo amahlu, kunye namasisthemu amancane okusetyenziswa. Amaphrojekthi amandla apha amanani a-PSA amakhishwe ngamathambo amancane okusetyenziswa okugcina amaparamitha amahlukeneyo kunye nokusihlukanisa ukusuka komthetho wamaxhobo amahlu. Lezi ziphrojekthi zikhuluma kakhulu kuzamaliso, izindlela zokusebenza, uphawu lwamanye amaxesha, kunye nemibhalo yezivathango ezincedisiyo apho umthetho omncane wamaxhobo amahlu kufanele.
