1. A process for treating HAPs in air to ultra-low emission limits, said process to include the steps of:

  • a. Passing the air stream through a bed of synthetic adsorbent, b. Removing the adsorbent to a regeneration column;

    c. Regenerating the adsorbent at elevated temperature and above-atmospheric pressure in a highly turbulent fluidized bed operating as an equilibrium-stage column;

    d. Cooling of the adsorbent;

    e. Placement of the adsorbent back into the adsorption bed;

    f. Destruction of the HAP vapors using a catalytic oxidizer, g. Scrubbing of the vapors with a caustic scrubber or solid basic adsorbent to remove acid gas; and

    h. Exhausting the regeneration air stream to the atmosphere.
