Paper Title:
Research of Equipment Applied for Distillation of Viscous and Self-Polymerized Materials
  Abstract

Distillation column of special materials having high viscosity or containing solid particles, etc in chemical and petrochemical process is studied in this paper. Packed-column does not fit into this situation and even in a plate column, because of high flow resistance on the plate; it will cause some problems, such as blocking, flooding and shutting down. Here the hydrodynamic performance of flow-guided fixed valve trays (FFVT) is introduced and its hydrodynamic performance has been experimentally studied. With flow-guided holes and trapezoid fixed valves to transfer momentum of the gas bursting forth in a horizontal way to the liquid, the flow on the FFVT is well-proportioned and stable. The hydrodynamic data have been correlated and equations have been obtained for the pressure drop, the entrainment and the gas velocity at weeping point, which can be used for the design of FFVT.
