Drain & Seal Pots
A condensate seal pot/auto-drain seal pot is used in gas pipelines to accumulate and drain condensate, dust and other contaminants. As condensate levels rises in the pot, a float lifts and the condensate, along with dust and other contaminants, is discharged. Once purged of the condensate, the float falls immediately and seals the outlet nozzle. Auto-drain seal pots are mission critical.
The operating pressure and temperature of the gas are used to design the various parameters of the auto-drain seal pot. The float and bottom seal arrangement has to achieve the conflicting requirements of negative buoyancy and effective sealing but appropriate design and selection will help drive process performance.
