Abstract
A de-entrainment device separates entrained liquid from vapor in a fluid stream that flows through a chimney tray in a distillation tower. The separated liquid is collected and shielded from the fluid stream to prevent re-entrainment of the liquid in the vapor flowing upward into the tower. The chimney tray includes risers with hats that have gutters to guide liquid toward the tray deck, channels to collect and drain liquid from the top of the hats to the tray deck, and baffles extending from the risers to shield the liquid collected on the tray deck from the vapor flow.
