HERMANS, J.. Protect your catalyst by improving your sulphur filtration process. J. S. Afr. Inst. Min. Metall. [online]. 2017, vol.117, n.11, pp.1009-1010. ISSN 2411-9717.  https://doi.org/10.17159/2411-9717/2017/v117n11a3.

Downtime of a sulphuric acid plant is costly. Poor catalyst screening due to loss of high pressure on the catalyst bed is one of the major reasons for downtime. Sulphurnet has developed a technology that improves the efficiency of the liquid sulphur filtration process. Less ash is transferred to the catalyst. This enables acid plants to run for 28 to 30 months without catalyst screening. Other advantages of the process are reduced losses of liquid sulphur in the filter cake, and lower maintenance costs due to the longer lifetime of filter leafs. Finally, we address some environmental issues to reduce emissions and the losses of the sulphur in various areas.
