Maximizing Heat Transfer Without Shutdown
Online Reboiler Cleaning in SDA Unit Restores Performance by 49% Using Rezyd-HP
When a major U.S. refinery experienced severe shell-side fouling in a reboiler on its solvent deasphalting (SDA) unit, traditional cleaning methods would have required a full shutdown, an expensive and time-consuming option. ZymeFlow’s engineered online cleaning solution using Rezyd-HP restored exchanger duty from 35% to 52% of design capacity, increasing steam flow by 500 lb/hr and extending runtime. This case study highlights how Rezyd-HP’s high-performance chemistry delivers safe, effective fouling removal without interrupting operations.
