1. A method for the mixing and distribution of fluid over the top of a reactor bed, comprising:
collecting fluid on a collection tray having a top and a bottom, and having outlet ports therethrough; passing the liquid and vapor above the collection tray through the outlet ports into a mixing chamber below the collection tray and contacting and mixing the liquid and vapor in the mixing chamber; passing at least a portion of the liquid through a generally central outlet of the mixing chamber to a distribution tray therebelow; passing at least a portion of the vapor through a vapor chimney having an upper opening within the mixing chamber and positioned radially outward of the mixing chamber outlet to introduce the vapor portion into the distribution tray radially outward of the liquid portion; distributing the vapor and liquid below the distribution tray.
