Less waste and better working solution
The application of a very fine filter cloth in the self-cleaning candle filter (0.5 micron) stopped the bypass of the particles so no conglomeration could take place. The result was less production stops, reduction of maintenance and an improvement of working conditions for operators. Furthermore, the filters contributed to the product recovery since the solids could be recycled to the belt filter and recovered as valuable end 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 is not the filtration that is causing the problem. Process design and operation procedures are more likely to be the cause of the poor quality of sulphur entering the sulphur burner.
What is happening inside the filter? (II)
Now that we understand the 3 main possible outcomes of the pre-coat layer (see the article here), we must understand these are the worst and best possible scenarios, these possibilities are in a line from low flowrate to high flowrate. This means that you can find any deviation in along this line, knowing how the particles behave and how the shape the cake is formed will give you a good understanding of there you are and how close you are to the ideal filtration cake.
Now let analyse what will happen in each scenario of pre-coat layer, when you have another 3 scenarios with the main filtration.
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. Flowrate control must be continuously improved along the rest of the filtration system.
The filter cake, the pump curve and the pressure differential express about the flowrate. Understanding what is going on inside the filter can give us a good idea of what may be causing a problem and how to solve it.
Simple Solutions for High Ash Content Levels
Many sulfur burning plants are plagued by high ash content levels , and then contamination of the waste heat boiler and catalyst bed in the converter of the acid plant. The answer to this problem is ...
