Operation Principle
Oil-filled screw compressors are used as a source of compressed air in the unit.
Compressors are designed to supply Class 1 compressed air with a capacity of 27 to 451.8 m3/hour, as well as to supply air for valve actuators instrumentation.
When leaving the compressor, air passes through a cyclone separator, which significantly reduces the overall load on mainline filters and also retains oil particles.
After the cyclone separator, the compressed air with saturated vapor enters a refrigerated dryer to reduce compressed air moisture content.
For units with adsorption dryers, after the cyclone separator, the compressed air enters the adsorption dryer, which is designed to remove moisture contained in compressed air produced by the air compressor until its dew point reaches 20˚C to 40˚C and below.
Further, dry air passes through main filters to remove oil, dust, and other particles up to 0.01 µm in size.
After the main filters, air enters the air receiver, which is designed to smooth compressed air flow irregularities created by the compressor and also acts as a compressed air ‘accumulator’ in a pneumatic network.
Then the air passes through an antibacterial filter designed to clean the air from microorganisms: bacteria, bacterial contaminants, yeasts, fungi, and their products.
The technological process is fully automatic due to the control system and does not require intervention and constant operator control.
The control system continuously monitors pressure value via a pressure sensor and regulates pressure in the network by switching the compressor on and off.
The control system allows compressors to be cycled on a timer to equalize running time.
The controller has a timer delay function to avoid simultaneous compressor start-up.
