Green oil is an oligomer formed in the hydrogenation reactors. If you use fuel gas to regenerate the dehydrator it strips the green oil from the mol sieves and can foul the burners in the furnace.

Check if you've had a level upset in the green oil separation drum? It may have entered through the fuel gas line to the vapour space.
