; ; ;
A sulfur trioxide-containing fluid, e.g., sulfur trioxide gas, is contacted with the surfaces of equipment in contact with crude oil or natural gas to retard the deposition of paraffins from the crude oil or natural gas 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.
