The vapor and mist enter the bottom of the cyclone (inlet) and flow through an activator element that imparts a very high centrifugal force. The droplets are flung outward and are coalesced into a liquid film on the cyclone inner wall. The liquid film and a small portion of the vapor flow are purged out of the cyclone through openings in the wall into an outer chamber where the gas and liquid separate. The bulk vapor is discharged from the top of the element (outlet). The collected liquid is drained from the cyclone deck via downcomer pipe.
