The Claus waste heat boiler (WHB) is a critical piece of equipment in the sulphur recovery unit (SRU). As processors move towards higher sulphur feedstocks, more load is placed on the SRU, and WHB failures are becoming more common.
As documented by the authors, it is well known in industry that sulfur recovery unit waste heat boilers (WHBs) can fail due to a wide variety of reasons. The primary modes of reported failure include departure from nucleate boiling (DNB) and sulfidation corrosion. From A Robust SRU Waste Heat Boiler Design
The Claus Waste Heat Boiler (WHB) is a critical piece of equipment in a Sulphur Recovery Unit (SRU); its fundamental purpose is as a heat transfer device used in energy recovery. Sulphur plant operators have recently been experiencing higher than normal WHB failure rates, perhaps from oxygen enrichment and pushing rates.
cleaning system on their waste heat boilers. SRU Function and Performance In refinery operations, the emission limits are very restrictive and often utilize the improved Claus SRU recovery system. The efficiency of the Claus sulfur recovery unit can deteriorate with time if the boilers, converters, and condensers have deposit buildup.
Waste Heat Recovery. With the high cost and environmental impact of fossil fuels, heat energy is a precious commodity that cannot be wasted. Any exhaust gas stream with temperatures above 250°F has the potential for significant waste heat recovery.
