Tray Design and Operation
1010302Tray Design and OperationOnce the process design is completed, the equipment design begins. This phase of the design translates the process requirements (i.e., the vapor and liquid loads in each section of the column) into actual hardware.The hardware design proceeds in two phases: primary (basic) and secondary (detailed layout). The primary phase sets column diameter, type of tray, and split of tray area into bubbling and downcomer areas. This phase also provides a preliminary (and usually close) estimate of tray spacing, number of passes, and other features of tray and downcomer layout such as weir height, fractional hole area, hole diameter, and clearance under the downcomer. These estimates are later firmed up in the secondary…
