Patent
·
OSTI ID:6727012
This patent describes a method of treating a highly paraffinic hydrocarbon liquid containing not more than 5 wt% aromatics and from 10 to 10,000 ppm high molecular weight asphaltenes to prevent asphaltene fouling of equipment at temperatures below 400{degrees} F. It comprises: adding to the hydrocarbon liquid not less than 10 ppm and not more than 200 ppm of an oil soluble overbased magnesium alkyl aromatic sulfonate to inhibit asphaltene fouling.
