ABSTRACT:
Process and apparatus for the generation of sulphur trioxide from oleum using microwave energy for use in the sulphonation and nitration of organic compounds and the fortification of oleum. The process provides improved control of production and concentration of the sulphur trioxide produced and comprises subjecting sulphur trioxide-rich oleum feed to microwave energy for a sufficient period of time to produce sulphur trioxide vapour and spent oleum; isolating said sulphur trioxide vapour and collecting said spent oleum.
