Sulphuric acid plant equipment

Ceramic Packings


Features and Benefits

AWS packing is made through a slip casting process which produces saddles of uniform shape within a narrow range of size tolerances. We ensure high strength and uniform shape.

Our packings are made of a high-quality clay, with specially formulated chemical composition and controlled grain size distribution is used resulting in a saddle with very high crush strength and very low porosity.

Acid absorption is less than 1 percent.
Breakage during shipping and installation has typically been less than 0.1 percent.

Excellent mass transfer rates at low pressure drop
Proven semi-torroidal saddle shape which provides random interlocking and uni-form void space. This conventional shape has been modified to reduce pressure drop and promote mass transfer efficiency.

Large apertures are provided at the hub of the saddle to break up the gas and acid streams, thereby reducing gas flow resistance and improving acid surface renewal frequency for enhanced mass transfer.

Notches at the edges of the saddle wings provide additional acid drip points and promote surface renewal.
