Document Type and Number:
Japanese Patent JP5066532
Kind Code:
B2
Abstract:
An improved de-entrainment device for use in distillation towers, especially vacuum distillation towers used for fractionating petroleum atmospheric resids is in the form of 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.
