The present disclosure relates to an antifoulant formulation comprising: (a) at least one ammonium salt of linear alkyl benzene sulphonic acid; (b) at least one aromatic hydrocarbon; (c) at least one diluent; (d) polyisobutylene succinic anhydride; and (e) at least one alkyl amine. It also relates to the process of preparation of the said antifoulant formulation. The instant disclosure further relates to the method of inhibiting fouling tendency in the heat exchangers of crude oil, crude blends, short residue, involving the said antifoulant formulation. La présente invention concerne une formulation antisalissure comprenant : (a) au moins un sel d'ammonium d'acide alkylbenzènesulfonique linéaire ; (b) au moins un hydrocarbure aromatique ; (c) au moins un diluant ; (d) de l'anhydride succinique de polyisobutylène ; et (e) au moins une alkylamine. L'invention concerne également le procédé de préparation de ladite formulation antisalissure. La présente invention concerne en outre le procédé d'inhibition de la tendance à l'encrassement dans les échangeurs de chaleur de pétrole brut, de mélanges de bruts, de résidus courts, impliquant ladite formulation antisalissure.
