1. A process for separating a mixture of two gaseous components having different boiling point temperatures formed during a re-utilization of PUR-foamed plastics, comprising the steps of:

  • compressing said mixture for raising the temperature of said mixture above the boiling point temperature of the gaseous component to be eliminated;

    cooling said mixture of two gaseous components below the boiling point temperature of the gaseous component to be eliminated from said mixture, said gaseous component to be eliminated thereby being liquefied by condensation;

    discharging the liquefied gas component of said cooling step into said tank thereby eliminating from said mixture the gaseous component to be eliminated and leaving a resulting gaseous mixture;

    expanding the resulting gaseous mixture; and

    ,exhausting the resulting gaseous mixture through at least one activated carbon filter for removing any remaining gaseous component to be eliminated.
