Tray Column Design: chimney tray
Distillation and absorption tray column design parameters — sieve, valve, bubble cap, dual-flow, baffle, and chimney tray geometry, hydraulics, flood limits, and turndown ratios; plus system derating factors, downcomer hydraulics, downcomer residence times, typical theoretical stages by separation system, and Murphree tray efficiency ranges
