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. BACKGROUND Low-finned (LF) and DE tubes are widely accepted as standard solutions in shell-and-tube HEXs in many industries such as air conditioning and refrigeration, power, the HPI and machinery and equipment indus
