Abstract
A system and process for removing water and heteroatom-containing compounds from hydrocarbons and for regenerating the adsorbent used in the system and process is disclosed and includes contacting the hydrocarbon stream with a water adsorbent and a heteroatom-containing compound adsorbent. The regeneration includes passing an isoparaffin over the water-adsorbent, then passing the isoparaffin over the heteroatom-containing compound adsorbent; and, optionally; cooling the effluent; separating such into a hydrocarbon phase and a water phase in a settler; removing a portion of the hydrocarbon phase for mixing with water; returning the hydrocarbon/water mixture to the settler; removing some of the hydrocarbon phase from the settler to form a recycle isoparaffin stream for use as a portion of the stripping stream; and removal of a portion of the water phase from the settler to form a waste water stream containing water and heteroatom-containing compound.
