A process is provided for the removal of solvents and other contaminants from an inlet solvent laden air (SLA) path. The process comprises the step of passing the SLA through an adsorbent in an adsorber. The adsorbent is regenerated when it becomes saturated with solvents. The regeneration step is performed by passing a regenerating fluid, preferably steam, through the adsorber. The steam removes solvents from the adsorbent and transports the solvents out of the adsorber. The steam and solvents are condensed in a condensation step. Water is separated from the condensaton produced in a separation step such as decantation and distillation. The condensed water is passed to a steam generation step. The recovered water is used as boiler feed water to generate low pressure steam. The steam generated in the steam generation step is recycled to the adsorbent regeneration step. The recycling of the water used for regenerating the adsorbent eliminates a waste water stream, thereby eliminating or reducing waste water treatments.
