Iimveliso zeyunithi yolwahlulo lomoya-olulwelo lonke ingaba yioksijini enye okanye ngaphezulu, initrogen engamanzi kunye ne-argon yolwelo, kwaye umgaqo wayo umi ngolu hlobo lulandelayo:
Emva kokuhlanjululwa, umoya ungena kwibhokisi ebandayo, kwaye kwindawo yokutshintshiselana kobushushu, utshintshiselwano lobushushu kunye nerhasi ye-reflux ukufikelela kubushushu obusondeleyo bokuntywila kwaye ungene kwikholamu esezantsi, apho umoya wahlulwe kwangaphambili ube yinitrogen kunye nomoya wolwelo otyebileyo oksijini. , initrogen ephezulu ijikwa ibe yinitrogen elulwelo kumphunga ojiyayo, ize ioksijini engamanzi kwelinye icala ibe ngumphunga. Inxalenye ye-nitrogen yolwelo isetyenziswa njengolwelo lwe-reflux lwekholamu esezantsi, kwaye inxalenye yayo ipholile kakhulu, kwaye emva kokuphola, ithunyelwa phezulu kwikholamu ephezulu njengolwelo lwe-reflux lwekholamu ephezulu, kunye nenye inxalenye. ifunyanwa njengemveliso.
