Small Capacity Low Pressure Cylinder Filling Plants

Features of Small Capacity Low Pressure Cylinder Filling Plants:
* Range: 40 tO 800 M3/hr.
* Purity oxygen: 99.6%. Nitrogen: 99.99% or 3PPM
* Operating Air Pressure: 0.6 TO 0.7Mpa

Basic Principle:
The air separation plant is a plant recovering oxygen and nitrogen from air simultaneously. It advance low pressure technology process using rotary screw compressor (or low oil free piston compressor)and turbo expander. The feed air entering the Molecular Sieve purification system employed to remove the moisture and Co2 from the process air. The air is liquefied by cryogenic cooling using latest plate and fin high efficiency heat exchangers and turbo expander. The liquid air separates into oxygen nitrogen and inert gases in the air separation column.

Main Components

1.Air Compressor:
Rotary air compressors screw type can be used for smaller size plants upto 500m3/hr & 1000m3/hr. Centrifugal compressor can be used for higher size plants.

2.Air pre cooling system:
Air separation plants adopts chilling system in all air pre-cooling systems.

3.Air purification system:
This system beds of molecular sieve are used in the air purification system, it remove the Co2 & moisture for the process air at low-pressure
