Resumen
Las columnas de bandejas son esencialmente cilindros verticales en los cuales el líquido y el gas son puestos en contacto en operación por etapas en platos, y son útiles para procesos de absorción destilación. En el presente artículo se llevó a cabo el diseño de una columna de bandejas perforadas para la absorción física de amoníaco usando agua como solvente. Los valores calculados del diámetro de la columna, caída de presión del gas por bandeja, caudal másico de arrastre y la eficiencia de la bandeja de Murphree corregida para arrastre fueron de 0,962 m; 0,683 kPa/bandeja; 0,102 kg/s y 0,796 respectivamente. Los valores calculados de tanto la caída de presión del gas por bandeja y el caudal másico de arrastre son menores que los límites establecidos por el proceso; por tanto, la columna de bandejas perforadas diseñada puede ser empleada satisfactoriamente para el servicio de transferencia de masa requerido.
