Power Plants
Though you might not realise it, dry compressed air affects every unit in the Power Industry.
Use of Compressed Air in the Power Industry
In Power industry manufacturing units, the following compressed air-powered pneumatic machines are used :
- Emissions Control
- Ventilation System for Boiler House
- Pneumatic Controls and actuators
Applications
- Ash Handling System
- Insertion and withdrawal of reactor rods
- Starting gas turbine
- Stamping
- Tool powering
Problems
A major problem in compressed air systems is the presence of water, dust particles, oil (oil particles are introduced by lubricated air compressors), and solid contaminants, which can adversely affect air quality.
If the contaminated compressed air is used through pneumatic tools and machines, then there will be the following problems :
- Malfunctioning of pneumatic tools and machines
- Sluggish and inconsistent operation of valves and cylinder
- Corrosion in pipelines, cylinders and other components
- Increase in downtime
- Increase in maintenance cost of pneumatic machines/tools/controls.
- Freezing in exposed lines during cold weather.
The Delair Solution
Remove water, dust particles, oil (lubricated air compressors introduce oil particles), and solid contaminants from compressed air.
Delair offers a wide range of refrigeration and adsorption dryers that remove water/moisture from compressed air.
Delair refrigeration dryers
This dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.
Delair Adsorption dryer
The dryers are based on the principle of heatless regeneration and the physical properties of their desiccant to adsorb and desorb water vapour. They use the pressure swing principle / purge air to regenerate the desiccant bed.
Filters
Delair also offers Pre Filters and Oil Filters, which remove dust and oil particles and other types of solid contamination present in dry air.
Frequently Asked Questions
1. Where is compressed air used in pharmaceutical manufacturing?
Compressed air is used across pharmaceutical production and packaging operations. Common applications include lid sealing, capping, container feeding, liquid filling, blister packing, labeling, printing, conveying tablets and capsules, bottle cleaning, spray systems, and aseptic packaging.
2. How can moisture and contaminants affect pharmaceutical products?
Moisture and contaminants in compressed air can affect pharmaceutical product quality in several ways. Moisture may change tablet-coating colour, contribute to blisters or tablet breakage, and react with certain chemicals. Dust can also be problematic during powder-coating processes, while hygroscopic pharmaceutical products can be particularly sensitive to moisture.
3. What problems can moisture-laden compressed air cause in pneumatic equipment?
When wet compressed air enters pneumatic equipment, it can contribute to sluggish or inconsistent valve and cylinder operation, corrosion in pipelines and components, and equipment malfunctions. These issues can increase production downtime and maintenance costs, while exposed air lines may also be vulnerable to freezing in cold conditions.
4. What compressed air treatment solutions does Delair offer for pharmaceutical manufacturing?
Delair provides adsorption dryers to remove moisture fully from compressed air, along with pre-filters ,Fine filters and oil filters for dust, oil, and solid contaminants. adsorption dryers use desiccant material and regeneration to achieve drier air for applications with higher air-quality requirements.
