Nitrogen Plant Flow Sheet |
Nitrogen plant consists of the following equipment
1. Air compressor
2. Refrigeration unit
3. Moisture separator
4. Air purification unit
- Adsorbers
- Post filters
- Regeneration heater
- Air vent silencer
- Nitrogen vent silencer
- Main exchanger
- Medium pressure column
- Condenser vaporizer
- Waste nitrogen & air expansion turbine
- Liquid nitrogen/ gaseous nitrogen separator
7. Nitrogen vaporizer
8. Liquid nitrogen storage tank
9. Pressurizing coil
Nitrogen from the air is separated by compressing air and expanding it at low temperature. By means of cryogenic technology, continuous removal of heat and compression will make nitrogen to change its phase from gas to liquid phase, the liquid phase nitrogen is stored at high pressure and transported in cylinders.
