ABSTRACT

It is a known fact that that sulfur oxide emissions can have a negative impact on man and the environment. Although they have been decreasing steadily, these particles are still emitted by combustion plants powered by fuels containing sulfur as well as by other industrial processes. European directives have limited the level of these emissions in European countries, which has allowed for the development of desulfurization techniques over the last few decades. This article deals with these particles. It starts by presenting the sources of emission and impacts on the environment. It then proceeds to detailing manual or automatic measurement methods and concludes on existing treatment processes and on the effect of operation parameters on desulfurization techniques.

 INTRODUCTION

Sulfur oxides are emitted into the atmosphere from industrial sources by combustion plants powered by sulfur-containing fuels, and by many other activities in the manufacturing sector. Their harmful effects on man and the environment are well known: respiratory disorders, acidification of surface waters and soils, damage to architectural heritage.

Firstly, this article takes stock of the situation since the last publication on the subject in this treatise [J 3924] and the ADEME dossier. , on SO x emissions and the relevant regulations, limiting himself here to European directives. It also succinctly describes the many existing abatement processes, referring the reader, for further information, to these two previous contributions.

The second aim of this article is to analyse and explain in detail, in the light of studies published in the literature and the principles of physical chemistry and process engineering, the effect of operating parameters on desulphurization techniques, focusing on wet processes and, in particular, the lime-lime-gypsum process, the most widely used in the world.
