TPC Group replaces aging boilers with RENTECH units

The tubes are connected by ¼" x 1" carbon steel membranes to form a water-cooled enclosure. The furnace was sized at 13.0' W x 44.0' D. The furnace volumetric heat release rate for these units was less than 60,000 btu/hr-ft3, which is conservative for gaseous fuels but is key in achieving ultra-low-NO x conditions. Total furnace heat

Sulphidation corrosion in a claus waste heat boiler

Sulphidation corrosion and thermal cycling in Claus waste heat boilers (WHB) are the two leading causes of unexpected failures that result in unscheduled shutdowns of sulphur recovery units (SRU). Sulphidation corrosion is caused by two main factors: high temperatures, typically exceeding 650°F (343°C), and hydrogen sulphide (H2S).
