Abstract
Una columna de transferencia de masa (20) con una camisa externa (22) que define una región interna abierta (24). Bandejas de contacto centrífugas (26) y bandejas de contacto de retorno (28) se disponen alternativa y verticalmente separadas en el interior de la región interna abierta (24). Cada bandeja de contacto (26) y (28) posee una pluralidad de conductos de vapor (34) para permitir que el vapor fluya en dirección ascendente por la plataforma de las bandejas (30) y (31), respectivamente, para interactuar con el líquido en la superficie de la misma. Al menos un tubo descendente central (42) se extiende en dirección descendente sobre un orificio en la plataforma de bandeja de retorno (31) y posee una salida de descarga inferior (54). Al menos un tubo descendente anular (38) se extiende en dirección descendente por la periferia de la plataforma de bandeja centrífuga (30) y posee una salida de descarga inferior (48) separada de la plataforma de bandeja de retorno (31) para alimentar líquido a la plataforma de bandeja de retorno (31). Una pluralidad de tabiques (60) se extiende en dirección ascendente desde la bandeja de contacto de retorno (28) en el tubo descendente central (42) y transfiere una porción de la carga de la bandeja de contacto centrífuga a la bandeja de contacto de retorno. Una placa de soporte central (58) se dispone entre los extremos superiores de los tabiques (60) y la bandeja de contacto centrífuga superpuesta (26) en orden a proveer una mayor área de soporte. Un anillo de soporte (66) se fija a la camisa de la columna (22) y un par de barras de soporte (62) se fijan al anillo de soporte (66) y el tubo descendente central (42) para transferir la carga a la camisa de la columna (22). Trabas de fijación (71) se extienden entre el tubo descendente central (38) y otro anillo de soporte (70) para transferir otra porción de la carga de la bandeja de contacto centrífuga a la camisa de la columna (22). Un método de soporte de por lo menos una bandeja de contacto de retorno y por lo menos una bandeja de contacto centrífuga que poseen plataformas de bandeja con una pluralidad de conductos de vapor, al menos un tubo descendente central y al menos un tubo descendente anular en una columna de transferencia de masa.A mass transfer column (20) with an outer jacket (22) defining an open internal region (24). Centrifugal contact trays (26) and return contact trays (28) are arranged alternately and vertically separated inside the open inner region (24). Each contact tray (26) and (28) has a plurality of steam ducts (34) to allow steam to flow upwards through the platform of the trays (30) and (31), respectively, to interact with the liquid on the surface of it. At least one central descending tube (42) extends downwardly over a hole in the return tray platform (31) and has a lower discharge outlet (54). At least one annular descending tube (38) extends downward along the periphery of the centrifuge tray platform (30) and has a lower discharge outlet (48) separated from the return tray platform (31) to feed liquid to the return tray platform (31). A plurality of partitions (60) extends upwardly from the return contact tray (28) in the central descending tube (42) and transfers a portion of the load from the centrifugal contact tray to the return contact tray . A central support plate (58) is disposed between the upper ends of the partitions (60) and the superimposed centrifugal contact tray (26) in order to provide a larger support area. A support ring (66) is fixed to the column sleeve (22) and a pair of support bars (62) are fixed to the support ring (66) and the central descending tube (42) to transfer the load to the column shirt (22). Fixing locks (71) extend between the central descending tube (38) and another support ring (70) to transfer another portion of the load from the centrifugal contact tray to the column sleeve (22). A support method of at least one return contact tray and at least one centrifugal contact tray having tray platforms with a plurality of steam ducts, at least one central descending tube and at least one annular descending tube in a mass transfer column.
