The worldwide increase in the production and use of sulphur has led to a timely update by Sandvik Process Systems of its technical brochure on sulphur soldification and handling systems. There is a growing level of sulphur arriving in international markets. The key reasons for this are increases in world energy consumption demanding greater use of fossil fuels, natural gas, crude oil and coal with higher sulphur contents, and more intensive desulphurisation programmes being prompted by the environmental lobby and legislations on sulphur dioxide emissions.
The brochure describes the latest Sandvik developments in the processing of sulphur pastilles. There is also a major focus on environmental efficiency. Product cooling is effected by indirect heat transfer – water is sprayed on the lower surface of a steel belt – so that there is no danger of cross contamination between product and coolant, and the water can be re-used. Little air extraction is required and that which does pass through the exhaust, fulfils all usual emission standards without any treatment. Furthermore the low friability of Rotorformed pastilles means dust levels are so low that the solified sulphur can even be transported on open railway trucks. As well as giving a detailed presentation of the solidification system and its benefits, the brochure also illustrates high profile installations like the Caltex plant in Cape Town, South Africa, Shell’s Shantz plant in Caroline, Canada, the Econova plant in Sicily, Italy, and the Suez-Oil plant in Egypt.
