Monitoring the ash level in liquid sulphur prevents plant shut-down
The development in the sulphuric acid industry is going towards less maintenance stops, preferably running for 28-36 months. One of the criteria plants should asses continuously is the ash level in the liquid sulphur. Screening of the expensive catalyst is one…
Less waste and better working solution
Process optimization with self-cleaning candle filters. A producer of herbicides was investigating a plant optimization in which filtration played an important role. The process included a continuous reactor and the products were filters on a belt filter to recover the product,…
Above Ground Sulphur Melter: Advantages
Ashes entering the converter interferes with the formation of SO3. In a sulphur burning plant, sulphur filters usually catch the blame. A “polishing filter” can solve this problem. However, in numerous inspections of sulphur melting plants, Sulphurnet has discovered that it…
Filtration flow rate: What’s going on inside the filter? (I)
How the filtration flow rate affects the filter internals and what happens to the particles in the different scenarios? Believe it or not, the flow rate, especially in the pressure leaf filter, is a very critical point. Flow rate control must be…
Simple Solutions for High Ash Content Levels in Sulphur Plants
Many sulphur-burning plants are plagued by high ash content levels, which contaminates both the waste heat boiler and the catalyst bed in the acid plant’s converter. The answer to this problem is installing a liquid sulphur polishing filter after the pressure leaf filter. The…
