Join us at the CRU Sulphur + Sulphuric Acid 2024 Conference and Exhibition in Barcelona, 4-6 November, for a global gathering of the sulphur and sulphuric acid community. Meet leading market and technology experts and producers, network, share knowledge, and learn about market trends and the latest developments in operations, process technology and equipment.
In this case study, CS Combustion Solutions presents a comprehensive strategy for the capacity enhancement and optimisation of a sulphuric acid plant that was facing several operational challenges.
A new burner design for the combustion of natural gas with either combustion air or pure oxygen as the oxidiser has been developed by CS Combustion Solutions. The new Oxijet® -Burner has been designed to perform both start-up and main operation functions with one burner. The key objectives, challenges, and burner design considerations are discussed.
New state-of-the-art equipment has been installed in the thermal stage of one of Europe’s largest Claus SRU units. Substoichiometric firing and a furnace designed with CFD calculations and a modern compact boiler system design based on detailed heat engineering and FEM calculations were key to the success of the retrofit. P. Foith of CS Combustion Solutions reports on the retrofit and how the novel combination of a CS low pressure swirl burner, additional mixing using a VectorWall™ and a new waste heat boiler design achieved the desired results.
