  • Recycling process for adsorber regeneration
    Patent number: 10137400
    Abstract: The invention relates to a process for the regeneration of an adsorber. For the regeneration a liquid stream (S2) comprising at least one alkane is converted from liquid phase into gaseous phase. Then the adsorber is regenerated and heated by contact with gaseous stream (S2) up to 230 to 270° C. Subsequently, the adsorber is cooled first by contact with gaseous stream (S2) to a temperature of 90 to 150° C. followed by cooling with liquid stream (S2) to a temperature below 80° C. The outflow of the adsorber (S2*) during the cooling with gaseous stream (S2) and optionally the outflow of the adsorber (S2*) during cooling with liquid stream (S2) is recycled in at least one of these steps.
