    摘要: An improved de-entrainment device for use in distillation towers, especially vacuum distillation towers used for fractionating petroleum atmospheric resids comprises a baffle which is to be located in the portion of the tower below the feed zone and at the top of the flash zone. The baffle is in the form of an apertured plate above the stripping zone and in its preferred form comprises number of radial fins or blades, resembling a static fan with openings between the fins to permit vapors from the lower portions of the tower to pass upwards through the baffle with a minimal pressure drop. The fins of the baffle are preferably oriented at an angle between 30° and 60° away from the incoming feed so that the incoming feed stream skims over the top edges of the fins.

    摘要: This invention is a method for reducing the total acid number of organic acid containing petroleum oil comprising forming a water-in-oil emulsion comprising an aqueous Group IIA metal hydroxide solution or slurry in a hydrocarbon oil, said water-in-oil emulsion having an aqueous droplet particle size diameter of from 1 to 25μ, adding the water-in-oil emulsion to the organic acid containing petroleum oil and permitting the mixture to stand for a time sufficient to permit the neutralization of the organic acids in the petroleum oil.
