PCT No. PCT/SE90/00629 Sec. 371 Date May 7, 1992 Sec. 102(e) Date May 7, 1992 PCT Filed Oct. 1, 1990 PCT Pub. No. WO91/05597 PCT Pub. Date May 2, 1991.Method and apparatus for separating one or more agents, specially solvents, from gases. The agent or the agents are adsorbed by an adsorbent and thereafter desorbed and separated in a condenser (18). The regeneration of the adsorbent includes two steps. In the first step the agent or the agents are separated from a part of the adsorbent by heating. In this way the concentration of the agent or the agents is increased in those parts of the adsorbent which are closest to the condenser. In a second step the remaining parts of the adsorbent are regenerated. |
