Sulfur Dioxide Scrubber: pH Control | Yokogawa France

Scrubber System. The basic principle of a sulfur dioxide scrubber system is the removal of SO 2 by using its chemical characteristics to coine with water. In some cases, parallel rotating rods create a series of short throat Venturi openings. A series of low pressure, large orifice spray nozzles direct the scrubbing solution into the system.

Sulfur trioxide

Sulfur trioxide - SO 3. Sulfur trioxide is an anhydride to sulfur acid and in pure form it is a fluid. Gaseous sulfur trioxide is highly irritating to the eyes, throat and respiratory tract. It reacts with water and water vapour. Without water it’s not particularly reactive to metals. Properties. Molecular weight 80.066 g/mol

Sulfur Emission - an overview | ScienceDirect Topics

Sulfur dioxide SO 2 (g) is very water-soluble (cf. Section 5.3.3). Were it not for enormous amounts of sulfur dioxide in explosive eruptions far more than 25% would washout before reaching the stratosphere. There is no evidence aqueous sulfur dioxide SO 2 (aq) reacts with a water to form the hydrate sulfurous acid H 2 SO 3 (aq).
