Steel wire mesh and ceramic balls for catalyst loading in Klaus reactors
Thread Content
What is the mesh size of the wire mesh used for catalyst loading in Klaus reactors? What is the particle size of the ceramic balls? Does anyone know? :handshake
A screen is usually sufficient to ensure that the catalyst does not leak. Ceramic balls are generally placed in two layers: the bottom layer consists of balls with a diameter of φ25 or φ30, followed by another layer of balls with a diameter of φ12 or φ10, and finally the catalyst is added.

I do have some experience in this area: ceramic balls at the bottom should be either size 30 or size 25, and the gap between the grids is also important; the gaps I’ve seen are 24 and 19. I discovered this because, in 2012, a design error was corrected – ceramic balls with a diameter of 20 were used for gap 24. For screens, my personal choice would be 5-mesh and 13-mesh – something like that.
Thank you! ! :):):):)
The screen I’ve seen has a mesh size of 8–10 mesh. There are two types of ceramic balls: the larger ones have a diameter of φ30, while the smaller ones have a diameter of φ10. The larger balls are placed at the bottom, followed by the smaller ceramic balls.
Ceramic balls are available in sizes of 3mm/6mm/8mm/10mm/13mm/15mm/19mm/20mm/25mm/30mm/38mm/50mm/60mm/76mm/100mm. Have you placed an order for them?
The screen must be made of stainless steel, with a mesh size of around 10 mesh; it’s essential to ensure that the catalyst cannot pass through it no matter what angle it is from. For the ceramic balls, use two types: Φ10 and Φ30. The smaller ones should be laid at a thickness of 10 cm on the bottom, while the larger ones should be placed on top
For 10-mesh stainless steel mesh, it is necessary to find a reputable supplier; some products have an incorrect mesh size~
Okay, thank you:):):):):):)::D:D:D:D
Our plant’s Claus catalyst has a diameter of ∮6; the ceramic balls use a diameter of ∮10, and a 10-mesh steel wire mesh is sufficient. However, the wire mesh must be secured around the edges with compression strips to ensure no gaps remain.
Use a screen with a mesh size of 8 to 10. Place ceramic balls at intervals of 5 centimeters each; use ones with a diameter of ∮15 at the bottom and those with a diameter of ∮10 at the top. It is also possible to use a layer of balls with a diameter of ∮13 and a thickness of 10 centimeters. The edges of the screen must be properly handled, ensuring that their length does not exceed 15 centimeters. The fill material must be compressed tightly during installation
