In-line chamber for small gas exit nozzles
If the existing gas exit nozzle on the knockout drum is too small for inserting a MistFix unit, an in-line chamber can sometimes be provided for the device directly above the knockout drum as shown in Figure 8. This expedient comes into play when the exit nozzle diameter is smaller than the minimum 6 inches, or when the MistFix unit must be bigger than the nozzle to provide enough flow area within the available vessel height.
