Fluid distribution device and method for multibed reactors

摘要

A fluid distribution device and method is presented for the collection and distribution of fluid between reactor beds. According to various aspects, the method includes a collection tray, a mixing chamber in fluid communication with the collection tray, a rough distribution tray in fluid communication with the mixing chamber, and a fine distribution tray in fluid communication with the rough distribution tray. The rough distribution tray includes a vapor chimney.

主权项

1. A method for the distribution of fluid over the top of a reactor bed, comprising:
collecting fluid including vapor and liquid from a superior reactor bed; passing the fluid into a mixing chamber and swirling the fluid to contact the vapor and liquid; passing the fluid through a generally central mixing chamber outlet to a rough distribution tray; collecting the liquid on the rough distribution tray; passing the vapor radially toward an annular opening between the rough distribution tray and the reactor wall; passing one portion of the vapor through an opening of at least one vapor chimney having inwardly tapering cross section extending above the rough liquid distribution tray; passing another vapor portion through the annular opening to the fine distribution tray; distributing the fluid below the fine distribution tray to another reactor bed.
