Ammonia is removed from synthesis gas, or other gaseous solvents by utilizing a sorbent to remove the ammonia followed by an in situ regeneration of the sorbent and recovery of the ammonia. The ammonia is sorbed onto the bed of sorbent, thereby producing a purified gaseous solvent. Regeneration is achieved by using at least a portion of the gaseous solvent which is then acted upon to increase its solvent capacity for the ammonia and passed through the sorbent in the opposite direction to desorb the ammonia from the sorbent to provide an increased solvent capacity gaseous solvent. The ammonia is then recovered from the increased solvent capacity gaseous solvent.
