Abstract

A multipurpose chemical additives (MPC) is disclosed to mitigate fouling in hydrocarbon refinery processes, such as in a heat exchanger. A method for reducing fouling of a hydrocarbon is also disclosed that includes (i) providing a crude hydrocarbon for a refining process; and (ii) adding an additive to the crude hydrocarbon.
