ONLINE ZETA-POTENTIAL MEASUREMENTS FOR OPTIMIZATION OF EMULSION BREAKER DOSAGE IN ETHYLENE PLANTS

摘要

A method for treating an emulsion emanating from a quenching process in production of ethylene that includes online monitoring of zeta potential of the hydrocarbon/water emulsion in a quench water tower and/or a quench water loop. In response to the online monitoring of zeta potential, the method changes the amount of demulsifier being added to the hydrocarbon/water emulsion such that the amount of demulsifier is effective in breaking the emulsion.
