摘要： A delayed coking process for making substantially free-flowing coke, preferably shot coke. A coker feedstock, such as a vacuum residuum, is heated in a heating zone to coking temperatures then conducted to a coking zone wherein volatiles are collected overhead and coke is formed. A low molecular weight additive is added to the feedstock prior to it being heated in the heating zone, prior to its being conducted to the coking zone, or both.

摘要： A method of demulsifying a water-in-oil emulsion is provided. The method includes treating a volume of fluids comprising oil and water by adding a salt of a polynuclear, aromatic sulfonic acid to the fluids so as to cause the oil and water to be at least partially demulsified. The method may further include separating water and oil in a separator. A method of producing hydrocarbons from a subsurface reservoir is also provided. The hydrocarbons include a water-in-oil emulsion. The method includes producing the hydrocarbons through a wellbore, and subjecting the water-in-oil emulsion to a salt of a polynuclear, aromatic sulfonic acid additive so as to cause the oil and water to be at least partially demulsified.
