Process Equipment and Plant Design Weep holes provided in the plates of a distillation column Facilitate draining out liquid from a tray when the unit is not in operation Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation All of these Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid Facilitate draining out liquid from a tray when the unit is not in operation Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation All of these Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid ANSWER DOWNLOAD EXAMIANS APP
