摘要
A crude oil composition wherein fouling has been mitigating and a method for mitigating crude oil fouling. The composition includes crude oil and an improved dispersant material for mitigating fouling which comprises a reaction product of a polyamine and a polyisobutylene succinyl anhydride made with a polyisobutylene having a vinylidene double bond content of at least 50%. The reaction product has an active nitrogen atom content of at least about 2% by weight. The reaction product is prepared by thermally reacting the polyisobutylene with maleic anhydride to produce said polyisobutylene succinyl anhydride and thereafter reacting the polyisobutylene succinyl anhydride with a polyamine having 5 to 7 active nitrogen atoms. The method includes providing the dispersant material and dispersing the same in crude oil.
