Maganin MDEA wanda ya sha CO2 ana kiransa ruwa mai wadata, kuma yana zuwa tankin walƙiya. Iskar acid da ke fitowa ta hanyar rage matsin lamba tana haɗuwa da iskar acid da ke saman hasumiyar sabuntawa. Bayan ruwan mai wadata bayan walƙiya ya canza zafi da ruwan (ruwa mai laushi) da ke fitowa daga ƙasan hasumiyar sabuntawa, ana dumama shi zuwa ~95 ℃ kuma yana zuwa saman hasumiyar sabuntawa, inda ake cire shi kuma ana sake farfaɗo da shi har sai matakin ruwa mai laushi na ruwan mai laushi ya kai ga abin da ake so.
Ruwan da ke fitowa daga hasumiyar sake farfaɗowa yana ratsa ta cikin na'urar musayar zafi mai laushi ta ruwa mai laushi sannan ya shiga tankin ajiyar ruwa na MDEA.
