SULPHURIC ACID / CERAMIC TOWER PACKINGS

PROCESS INFORMATION

In a Sulphuric Acid plant contact section there are Drying and Absorption Towers, which are fitted with and acid distribution device, which sprays or flows Sulphuric Acid downwards into a bed of (usually) random packings which allow the upward flowing gas to contact the counter-current flowing acid, thereby achieving drying of air or absorption of SO₃.

Begg Cousland supply high quality ceramic tower packings from China and India, which we distribute, with our guarantees. We offer saddles, rings and cross-partition rings. They have been widely used worldwide, many times by major contractors and end users.
