Abstract
An improvement in the operation of a thermal oxidizer during regeneration of an adsorber, wherein adsorbates collected in the adsorber are removed from the adsorber and introduced into the thermal oxidizer, by regenerative steam passed through the adsorber, to be oxidized in the thermal oxidizer during a regenerative cycle of prescribed duration, regulates the concentration of adsorbates in the regenerative steam passed to the thermal oxidizer such that the concentration of adsorbates introduced into the thermal oxidizer throughout the duration of the regenerative cycle is regulated to avoid excessive deviations from a selected average concentration of adsorbates, the regulated concentration of adsorbates enabling more efficient operation of the thermal oxidizer throughout the full duration of the regenerative cycle.
