摘要： Carbonyl species contamination of liquid hydrocarbon media and corrosion of metal surfaces in contact with such media are inhibited. A high boiling point primary or secondary amine is added to the desired liquid hydrocarbon medium, and in one exemplary embodiment, the medium is then brought into contact with a separatory membrane such as a nanofiltration membrane. The permeate from the membrane is a highly purified hydrocarbon stream.
