Method for removing solids and water from petroleum crudes
Particulate solids and water are removed from petroleum crude to bring the BS and W content of the crude within pipeline specifications by treating a blended and dewatered crude to destabilize the water-in-oil emulsion of the crude and providing in uniform distribution through the treated crude both produced water and an acid-reacting coagulating agent while maintaining the crude at a pH of at least 8, then maintaining the resulting treated crude at 52/sup 0/-88/sup 0/ C. for at least a few minutes, separating the treated crude into at least an oil phase and a water phase, and recovering the oil phase as a clean blended crude oil having a BS and W content within pipeline specifications and in a yield significantly greater than that which can be recovered without use of produced water and coagulating agent.
