Sulfur Recovery Unit | Reaction Furnaces

A firetube waste heat boiler is typically located directly downstream of the reaction furnace. This waste heat boiler generates waste heat steam while cooling the reaction furnace effluent. The inlet tube sheet of the reaction furnace waste heat boiler is typically refractory lined with ceramic ferrules located on the inlet of each tube to prevent damage to the tube sheet and the tube sheet welds.

SPE-188706-MS Corrosion Control in Sulphur Recovery Units …

Sulfidation corrosion in Claus Waste Heat Boilers (WHB) is one of the leading causes of unexpected fail-ures that result in unscheduled shutdowns of Sulphur Re-covery Units (SRUs). Sulfidation corrosion is caused by two main factors: high temperatures, typically exceeding 650°F or 343°C, and hydrogen sulphide (H2S). Both fac-tors are prevalent in an SRU, especially in the front-end where the Reaction Furnace and WHB operate. Refrac-tory lining is used as protection wherever metal surfaces may see high temperatures and H2S. Other special pro-tection measures are put in place in the front end of the WHB in the form of ceramic ferrules to protect the tube-to-tubesheet transition joint as well as the first several inches of tubing. It's in this region of the WHB …

Case study: Extend tube life in a waste heat boiler

30/7/2020 · The sulfur recovery unit (SRU) separates sulfur from sulfur compounds. Within the SRU, a waste heat boiler (WHB) produces high-pressure steam, using the heat generated in this process. Since it operates in a high-temperature, high-hydrogen sulfide (H2S) environment, the WHB tube is often corroded by high-temperature sulfidation (HTS), and damage to the tube and tube joint frequently occurs.
