A volatile liquid vapor recovery system is used to recover vapors produced in the loading of shipping vehicles with volatile liquid product from a storage tank. The recovery system uses a primary vessel with an adsorption bed for adsorbing the volatile liquid vapors and venting clean air including oxygen to the atmosphere. The recovery system regenerates the adsorption bed by recovering the volatile liquid vapors from the adsorption bed and directly delivering said vapors to the storage tank. The system may be adapted to remove oxygen from the primary vessel prior to regeneration, such as by purging and venting the primary vessel with a purge gas or by providing a secondary vessel to receive oxygen and vapors from the primary vessel prior to regeneration of the first adsorption bed. Adsorbed volatile liquid vapor from the secondary vessel can be recycled to the primary vessel for conservation.
