liquid sparger design guide
PROCESS MECHANICAL DESIGN FOR DISTILLATION ,
A key design rule is to prevent the hold-up of liquid on the trays at shutdown Drain holes are, therefore, specified in the low points of the tray where liquid could collect While most distillation column internals will contain many holes, this does not guarantee that all the water will be drained...
