/ - OIL ANTI-FOULANT AND/OR ASPHALTENE AGGLOMERATION PROCESS

摘要

Pollution and/or asphaltene agglomeration (or agglomeration) in the midstream process and transport and upstream transport of hydrocarbon oils includes (A) polyalkenyl-substituted carboxylic acids or anhydrides, and (B) hydrocarbyl-substituted hydroxybenzos. Eight metal salts, hydrocarbyl-substituted sulfonate metal salts or mixtures of these two salts or additives comprising a metal detergent system comprising a complex thereof are reduced by providing the hydrocarbon oil with (A) versus ( The mass:mass ratio of B) is 20:1 to 1:20, and the treatment rate of the additive combination ranges from 5 to 10000 ppm by mass.
