INTRODUCTION
Metal dusting is a carburisation phenomenon that can cause rapid and often unpredicted failure in chemical
and petrochemical plants. Processing high temperature gases such as in the synthesis of hydrocarbon
feedstocks, methanol and ammonia, as well as in direct iron ore reduction often involves creation of gas
streams having high carbon activity with high ratios of carbon monoxide-to-carbon dioxide and low ratios
of steam-to-hydrogen. When such gas mixtures are present in the process stream within the critical
temperature range of roughly 400-750°C, metal dusting can be a severe corrosion problem. Chemical
reactors, furnaces, steam generators and down-stream reformer components can all suffer from this rapid
form of material wastage, resulting in costly downtime. In the case of syngas generation, processing
conditions and the use of advanced nickel oxide-based catalyst systems have heightened the tendency of
synthetic gas streams to promote metal dusting. The technique of injecting sulphur containing species into
the gas stream is no longer viable given the likelihood that the catalyst will be poisoned. Higher reforming
gas pressures and temperatures in conjunction with lower steam-to-carbon ratios, all combine to make
metal dusting conditions more aggressive, and are becoming more common in
