【Abstract】 The liquid residence time distributions (RTD) and flow pattern are studied by tracer technique for a water/air system in an experimental semicircular sieve tray of 2 meters in diameter.Complicated mean RTD profiles on a large sieve tray are observed.A mathematical model based on residence time profiles for a large tray is developed to compute the concentration profiles as well as the Murphree tray efficiency from point efficiency.The calculated plate efficiencies are in good agreement with the value found in literature.更多还原
