Abstract (en)

[origin: WO2021074267A1] The invention relates to a method and an arrangement wherein gases are removed via semipermeable membranes from aqueous, optionally complex biological substance mixtures by dialysis in an aqueous medium. Special carrier molecules for gases are used in the dialysate and these carrier molecules are regenerated in the dialysate circuit so that they can be used for further gas exchange cycles on the membrane.
