Though they look very different

UOP SimulFlowTM

Koch-Glitsch Ultra-FracTM

Jaeger CoFloTM and Shell ConSepTM trays fall into the same category of trays using inertial separation technology. However

flooding mechanisms and the trends of entrainment and efficiency are different due to their different working principles. This paper provides a detailed analysis of these trays using available information from literature and U.S. Patents. Efforts are also made to interpret the observations reported. In terms of tray efficiency

it is found that SimulFlow

UltraFrac and CoFlo trays are typical point efficiency devices due to a completely mixed liquid pool on the tray deck

while ConSep trays can take advantage of liquid concentration gradient on the tray deck

which makes this tray attractive among all ultra high capacity trays.
