Technology for Improving Water-Fuel Oil Emulsions Properties Using Polycarboxylic Acids

The technology of improving water-fuel emulsions (WFEs) properties through modification of IFO-380 marine fuel oil with aqueous solution of polycarboxylic acids surfactant was researched. Aqueous solution of the surfactant was used as water phase at WFEs production as well as emulsifier and corrosion inhibitor. It was established that viscosity, fluidity and corrosive activity of the obtained WFEs matched those of the unmodified IFO-380 marine fuel oil, while sulphur content, vanadium and coking parameters of the WFEs were lower, than those of the bunker fuel oil. An average size of water particles in the WFEs was 1–3 µm.
