DETERGENT SULPHONATION / BEFORE THE SULPHONATION REACTOR

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...

DETERGENT SULPHONATION / AFTER THE SULPHONATION REACTOR

SO3 gas is used in a sulphonation reaction process. Fibre filters which are installed after the sulphonation reactor remove up to 4,000 mg/m³ sulphonated hydrocarbon mist.
Due to the high viscosity liquid produced with over sulphonisation, it is recommended (a) to...
