ABSTRACT:
De-entrainment devices are provided for separating an entrained liquid from a vapor stream exiting a flash zone in a separation column. Methods for utilizing the de-entrainment devices are also provided. In one embodiment, the de-entrainment device of the present invention is embodied in a de-entrainment tray that has a tray deck and a plurality of risers extending vertically up from the tray deck. The risers are provided with devices for imparting rotational movement to the fluid stream, which have the vapor stream and entrained liquid, entering the riser. The rotational movement imparted to the fluid stream causes the liquid to separate from the vapor stream and to flow upward along the riser walls. The de-entrained liquid is then transported from above the separation tray back into the flash zone by way of a liquid downcomer. The vapor stream separates from the liquid within the riser and flows out of the riser upward through the column. A riser hat is used to prevent a wash liquid from entering the riser and preferably also from entering the liquid downcomer.
