Spent sulphuric acid regeneration (SAR) process

Solubility in weak sulphuric acid is typical for most spent acid from refinery and nitration processes. If the dust and ash solids are not soluble in weak acid, electrostatic mist precipitators are required. The SO2 bearing gas is then dried by contact with 93 to 96% H2SO4 in a packed bed acid tower or drying tower.
