Filter Aids

Until some years ago, the filteraid market was almost entirely controlled by mineral filter aids like diatomaceous earth and perlite. In the mean time, filter aids, based on organic raw materials (cellulose, wood fibred and plant fibres) are becoming more and more popular. Cellulose products are fibrous where inorganic products are particle shaped.
 

The major advantages of using cellulose filter aids in the filtration of liquid sulphur are:

• Cellulose is converted to CO2 and H2O. This means no silica particles in the downstream towers. You will expierence an increase of catalyst life time and a reduction of shut downs and maintenance costs.
• Cake removal. Due to the structure of the cellulose the cake can be removed very easily, even thin filter cakes. The lifetime of the filter leafs is increased!
• Less consumption per m².
• Higher flow rates per m². 

We offer 2 gades sulphuraids:

• Sulphur aid fine: for common Canadian sulphur, medium to high impurities level.
• Sulphur aid extra fine: for refinery sulphur. Low level of impurities.
