Abstract

The Shell DeVOx Process is a new catalytic incineration process, developed to provide a cost-effective solution to VOC emission problems. Key features of the process are a low cost non-precious metal catalyst, possessing high activity even in the presence of catalyst inhibitors such as H2S, and a proprietary low pressure drop reactor (the Lateral Flow Reactor or LFR, also used in the Shell DeNOx System). The first commercial-scale DeVOx unit was installed in 1995 at a styrene-butadiene rubber plant in the Netherlands, and replaced a precious metal honeycomb combustion catalyst. Specific advantages of the DeVOx Process in comparison with honeycomb catalysts, as perceived by the customer, include the considerably lower catalyst cost, reduced down-time required for catalyst fills, and the thermal and mechanical robustness of the granular DeVOx catalyst. Extensive monitoring has shown that styrene and butadiene in the plant's off-gas are effectively combusted in the DeVOx unit, such that it can fully meet the most stringent of environmental targets. Additional DeVOx units are under currently under construction for applications in the paint spraying industry.
