For effective gas / sulphuric acid contact in the ceramic packing bed in a Drying Tower or Absorbing Tower, the acid must be distributed evenly and consistently over the cross sectional area inside the tower....

N 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....
