Abstract
Oppfinnelsen vedrører en. fremgangsmåte for fjerning av acetylen ved lavtemperaturluftseparasjon. Derved blir luften først komprimert, avkjølt i minst én omskiftbar varmeveksler, og til slutt separert i minst én destillasjonskolonne. Ifølge oppfinnelsen blir acetylen fjernet fra luften ved katalytisk oksidasjon før luften ledes inn i varmeveksleren ved en temperatur mellom 70 og 130 °C, fortrinnsvis mellom 80 og 110 °C. Vann og karbondioksid blir derimot i hovedsak fjernet fra luften i varmeveksleren.
