Abstract:

During the operation of a 220 kt/a ethylene plant, its quench system encountered some problems including the easy emulsification of quench water, the difficulty in controlling quench oil viscosity, the serious coking in heat exchanger, and the severe corrosion of the heat exchanger and its pipelines. These problems shortened the operation cycle of the quench system and increased the energy consumption of the plant. By taking some optimization operation measures, the long-term operation of the quench system is achieved.

Key words: quench system, long period, optimization measure
