Overbased Magnesium Deposit Control Additive for Residual Fuel Oils

摘要

Residual fuel oil and over-based magnesium composition for turbine fuel deposition inhibiting additive comprises 14 wt% to about 18% by weight of magnesium, and succinic anhydride and lower carboxylic acid an over-based magnesium that contains the second promoter reaction product sulfonate, carboxylate or phenate, or mixtures thereof. The addition of an additive to fuel oils such as residual fuel oils that contain a large number of asphaltene plugging of magnesium / asphaltene deposits or sediment, and the resulting filter is removed or reduced. The additive also is removed or reduced to vanadium corrosion by the turbine. The invention also has as an over-base reaction is a secondary accelerator lower carboxylic acid, preferably acetic acid and an acid anhydride, preferably in the production of which, over the base compositions or deposition inhibiting additive comprises a combination of dodecenyl succinic anhydride (DDSA) It relates to a method. ; The magnesium base over the deposition inhibiting additive, fuel oil, the carbon dioxide
