ABSTRACT:
Disclosed are a method for inhibiting corrosion in crude oil distillation towers, an improvement in crude oil fractionation, a method for dispersing iron sulfide in a hydrocarbon stream and a hydrocarbon dispersion using the reaction product of hydrocarbyl succinic anhydride and an amine. The reaction product has a molecular weight of from 500-800, the hydrocarbyl substituent has 6-20 carbon atoms, and the amine is selected from EDA, DETA, TETA, TEPA, PEHA, AEP, piperazine, 1,2-PDA, 1,3-PDA, IBPA, MDA or HMDA. The imide product is a filming inhibitor used to treat metal surfaces subject to mineral acid corrosion and disperse iron sulfide particles by adding 3 to 24 ppm to sweet or sour crude contacting the metal surfaces.
