Abstract :

The filtration of liquid sulfur is a key operation in sulfuric acid production. It is used to remove solids, which might plug the sulfur spray nozzles and shorter operating durations. Upon liquid sulfur filtration, the filter has to be pre-coated with a filter aid mainly diatomaceous earth. The aim of this conference is to share the results of the substitution of silica filter aid based, with cellulose filter aid based. The results show the same performance, for both quality filter aid, in terms of ash content in liquid sulfur. An increase in operating cycle time from 24 h to 72 h with an easy removal of cake without risk and no leaf degradation due to the abrasion was obtained by the use of cellulose filter aid.
