Abstract:

To solve the problems of pipeline corrosion and quench water emulsification in the quenching system of ethylene plant during industrial application, technical modifications were carried out including adding new injection points for corrosion inhibitor, replacing the type of corrosion inhibitor and introducing automatic pH control system. The problems were effectively solved, and the safe, stable, long-term, full-load and optimum operation of the ethylene plant was ensured.
