Cross-linked polymeric resins are widely used in the treatment of aqueous streams to remove contaminants, using the ion-exchange process. Resins have less often been used for treating hydrocarbon streams, especially to remove trace contaminants such as basic nitrogen, due to limited studies targeting commercial applications. It is proposed to study the treatment of light hydrocarbons such as ethylene and propylene using resin beads with focus on their effectiveness and operational issues such as high pressure drop or oligomer formation. An innovative resin material will also be experimentally tested for removing trace quantity of ammonia present in the ethylene stream.
