ABSTRACT:
A sulfur trioxide-containing fluid, e.g., sulfur trioxide gas, is contacted with the surfaces of equipment in contact with crude oil to retard the deposition of paraffins from the crude oil and/or to react with the paraffins already deposited on the equipment surfaces to produce a water-dispersible material which is removed with an aqueous liquid.
