Clean, dry air is critical to the success and efficiency for power generation systems, but contamination and condensation are unavoidable when generating compressed air. Dirty, wet air is still dirty and wet after compression. Without filtration and drying, the air will contain all the contaminants of the ambient environment.
Clean dry air is the necessary resource for power plants to insert and remove remote control valves in the reactor rod, steam and coolant circuits, and the ventilation system of the boiler room.
Based on the size of the compressor and the humidity in the climate, compressed air contains water as both liquid and vapor. A small 100-cfm compressor and refrigeration-dryer combination, operating for 4000 hours in typical climatic conditions produces approximately 2200 gallons of liquid condensate per year.
Water, in any form, must be removed for the system to run correctly and efficiently. That is why dryers are imperative to generate clean, dry air.
Air Dryers for your Compressor: Drying the air can range from trapping condensed water to preventing additional condensation of water. If too much water remains in the compressed-air supply, the price is paid in downtime, higher maintenance, corrosion, damaged product, and premature equipment failure.
Get to know a range of drying options that help eliminate the harmful moisture in your compressed air.
• Aftercoolers reduce the temperature and water content of compressed air.
• Bulk liquid separators remove liquid condensed in the distribution system.
• Particulate filters remove solid-particle contaminants down and separate bulk liquids from the air stream.
• Coalescing filters remove liquid aerosols and particles (not vapors) down.
• Refrigeration dryers generate dew points of 37° to 50°F.
• Desiccant dryers produce dew points of -40° to -100°F.
• Membrane dryers have variable drying capabilities from -40° to +35°F dew points, depending on flow. In most plants, one compressed air system supplies many applications. But actual point-of-use air quality requirements vary depending on the individual workstation or machine.
Best tip, compressed air should be treated prior to entering the distribution system and at each point-of-use. This approach provides the most economical system purification by removing residual contamination in the distribution system while ensuring that critical areas receive air treated to the highest purity – to protect valuable equipment and prevent expensive downtime.
