An anti-sludge agent effectively disperses Ashphaltene within the oil phase and inhibits the formation of sludge either by acting as a chemical barrier between the asphaltene particles and acid or by reacting with and solubilizing the sludge.
The anti-sludge agent works as a colloid stabilizer to prevent the formation of these deposits during acid treatments. In addition to preventing sludge formation,
it can also perform as a non-emulsifier to prevent some
acid oil emulsions and improve the performance of othernon-emulsifiers.
