Binary polyethyleneimine emulsion breaker compositions for ethylene plant quench water systems

Abstract

A binary polyethylenimine composition can be used to effectively treat quench water for an ethylene production process across a wide range of pH conditions observed in typical production to inhibit and/or break an emulsion in the quench water. The binary polyethylenimine composition includes a first hyperbranched polyethylenimine having a first molecular weight and a second hyperbranched polyethylenimine having a second molecular weight greater than the first molecular weight.
