NITROGEN VENTING TO ATMOSPHERE, CT
Existing equipment nitrogen sensors in this manufacturing facility were discharging liquid and gaseous nitrogen into a vent header that was terminated within the occupied space. Client needed to understand how much oxygen was being displaced from the space by Nitrogen gas and if it was below acceptable levels. Client also requested a design (if determined it was required from dilution calculation) for venting Nitrogen to atmosphere (outdoors).
Provided dilution calculation and field measurements and determined amount of oxygen displaced from the occupied space housing the equipment was below client’s acceptable limits.
Recommendations and Benefits
- Provided custom design to vent the nitrogen sensors to a vaporization chamber before venting to atmosphere.
- Eliminated the problem of nitrogen displacing oxygen from the space.
