Sulphur Tail Gas Thermal Oxidizer
Sulphur Control Without Compromise

Overview
CRA’s Sulphur Tail Gas Thermal Oxidizers are engineered to provide reliable, high-efficiency destruction of reduced Sulphur compounds, such as H₂S, COS, and CS₂, commonly found in Claus unit tail gas and Sulphur recovery processes. Operating at high temperatures with optimized residence times, our systems ensure complete oxidation and stable performance under variable process loads. Built with corrosion-resistant materials, high-integrity refractory linings, and optional heat recovery or pre and post scrubber integration, these oxidizers meet strict environmental standards for SO₂, NOₓ, CO, and unburnt hydrocarbons.
Key Benefits
Total oxidation of sulphur-bearing compounds, including H₂S, COS, and mercaptans
Operates at 1200–2700 °F (650–1480 °C) depending on sulphur load and process design
Detailed CFD, process simulations, and strict QC guarantee adequate residence times and high DRE
Engineered to absorb load swings from SRU upsets, start-ups, or shutdowns with stable combustion
Advanced pre- and post-combustion scrubbing technologies engineered to meet the specific needs of each application
The CRA Edge
