Summary

Viscose-producing industries are present in many different countries. They emit waste gases containing sulphur compounds, i.e. H2S and CS2, which can efficiently be removed in optimized biotrickling filters, with total elimination capacities largely exceeding 100 g.m-3.h-1, and removal efficiencies above 90%, at EBRT around 16s. The reactors can be operated under stable conditions for several years, provided some of the guidelines described in this chapter are followed. The selection of adequate materials for the reactor and its internal parts, as well as the packed bed are some of the key issues. Potential pressure drop problems related to excess biomass and sulphur accumulation at high loads, can easily be solved. This chapter offers valuable information and guidelines for anyone dealing with the removal of sulphur compounds from industrial waste gases.
