(13a) Design Guidelines for Propylene Splitters Efficiencies

Actual field tray efficiencies are affected by many factors. These include; 1) geometry and design of contacting trays, 2) flow rates and flow paths of the liquid and vapor streams, 3) composition and properties of the vapor and liquid streams, and 4) tower pressure. All these items can inversely affect tray efficiencies and there are field examples were some have greatly impacted tray efficiencies. This paper will review some case studies and develop some design best practices.
