Antifoulant formulation for inhibiting fouling in heat exchangers
A recently granted patent (Publication Number: US11993753B2) discloses an antifoulant formulation designed to inhibit fouling in liquid hydrocarbon mediums. The formulation comprises a combination of components, including salts of linear alkyl benzene sulphonic acid, aromatic hydrocarbons, diluents, polyisobutylene succinic anhydride, and alkyl amines. The weight ratios of these components are carefully specified in the claims, ensuring optimal effectiveness of the antifoulant formulation.
Furthermore, the patent also details a process for preparing the antifoulant formulation, involving the mixing of components at specific temperatures and durations. The method of inhibiting fouling in a liquid hydrocarbon medium using the formulated antifoulant is also outlined, specifying the weight ratio between the formulation and the medium. This innovative formulation and method provide a structured approach to combat fouling in liquid hydrocarbon mediums, particularly in preheat exchangers of crude and short residue, offering a potential solution to a common industry challenge.
