Filter solution for detergent sulphonation / before the sulphonation reactor sector - Chemical & Pharmaceuticals - Fine Chemicals

Process Information: SO3 gas is used in a sulphonation reaction process. Fibre filters which are installed before the sulphonation reactor remove very fine oleum mists. The SO3 gas (6-7%) can contain up to 7,000 mg/m³ of oleum mists, and due to the highly exothermic reaction, it is normal to trace heat and insulate the vessel to prevent oleum freezing.
