Refinery Antiscalant Method |
| abstract |
Reduction of fouling in hydrocarbon refining processes by adding an additive combination comprising (A) a polyalkenyl substituted carboxylic acid or anhydride, and (B) an overbased to crude hydrocarbons used in the refining process A permanent metal hydrocarbyl substituted hydroxybenzoate detergent, wherein the mass of (A) and (B): the mass ratio is in the range of 10:1-1:10, and the treatment rate of the additive combination is 5 by mass ‑1000ppm range. |
