In order to select the right type and size of the filter, it is often recommended to perform filtration tests for new applications. The main goal of these filtration tests is to determine the optimal filter media and filtration process conditions….
Sulphur Flour: The invisible destroyer
How Sulphur Flour slowly destroys your sulphur plant Sublimed sulphur is invisible for the eye and causes serious corrosion. Sulphur is a pH neutral product, but under the right conditions and when the sulphur is in contact with air and water,…
Sulphur 2019 + Sulphuric Acid, Houston
One more year, we will be present at the Sulphur + Sulphuric Acid Conference 2019 in Houston (4-7 November). Our stand is number 28. Our Project Engineer, Mathijs Sijpkes, will make a presentation about Purification of Bio-Sulphur on 7 November 2019…
COBRAS 2019
SULPHURNET is taking part in the COBRAS 2019 conference, which will be held in Foz do Iguaçu, Brasil on 14-17 October. We will talk about “Better Management Of Sulphur Section” on 17th October at 10:50 am. If you have any specific problems…
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…
What is happening inside the filter? (II)
Main filtration cake from ideal pre-coat Now that we understand the 3 main possible outcomes of the pre-coat layer, we must understand these are the worst and best possible scenarios, these possibilities are in a line from low flowrate to high…
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…
