POLYETHYLENIMINE AS A NEW EMULSION BREAKER FOR QUENCH WATER SYSTEMS

Abstract: methods to increase the efficiency and throughput of hydrocarbon stream cracking by inhibiting the formation of, or resolving an emulsion, in an ethylene production quench water system. the method includes contacting a non-alkoxylated branched or linear polyethylenimine (pei) with a quench water composition from the quench water system under conditions suitable to prevent the formation of an emulsion or to resolve the quench water composition into two immiscible phases.
