Abstract:
1. A method of at least partially removing a nitrogen compound from a hydrocarbon stream comprising: introducing a hydrocarbon stream to a distillation tower, where the hydrocarbon stream contains at least one nitrogen compound selected from the group consisting of ammonia and volatile amines; contacting the nitrogen compound with an amine scavenger in an amount effective to at least partially remove the nitrogen compound from the hydrocarbon stream, where the amine scavenger is selected from the group consisting of:  where the amine scavenger has an absence of a reaction product of a hydrocarbyl succinic anhydride and an amine; and contacting the nitrogen compound with the amine scavenger under reaction conditions sufficient to form an oil-soluble, non-corrosive, non-basic, thermally stable reaction product that remains in tower bottoms during distillation.
