Dual-enhanced (DE) tubes are widely used in shell-and-tube
heat exchangers (HEXs) in a range of industries. They have
become a standard in multiple clean services for the hydrocarbon processing industry (HPI)
over the last 15 years. Yet, operators as well as manufacturers
struggle with the lack of operating data for DE tubes,
especially in fouling type services. This article reports a
successful field test of DE tubes in a quench-water service for
a naphtha-based olefin plant.
