PROCESS FOR ISOLATING N2O

43 Abstract PROCESS FOR ISOLATING N20The present invention relates to a process for purifying a gas mixture comprising5 dinifrogen monoxide, at least comprising the treatmont of a gas mixture G-0 comprising dinitrogen monoxide to obtain a gas mixture G-A, at Least comprising the absorption of the gas mixture G-0 In a solvent mixture S-I to obtain an offs stream and a composition C-A, and the desorption of a gas mixture G-1 from the composition G-A to obtain a solvent mixture $-1', subsequent condensation of the gas mixture G-A to10 oblein a liquid composition C-1 comprising dinitrogen monoxide and a gaseous mixture C--K, wherein the gaseous mixture G-K is recycled into the process.No suitable figure
