The most efficient method of industrial oil degassing is vacuum processing, which removes air and water solved in the oil. [6] This can be achieved by: spraying of oil in large vacuum chambers; distributing the oil into a thin layer over special surfaces (spiral rings, Raschig rings etc) in vacuum chambers.
A space-filling model of the sulfite anion. Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO 2− 3. The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used.
