[labnetwork] Nitrogen Generation

[Iulian Codreanu]

Hi Joseph,

In my experience the pressure of the gaseous N2 entering the building is 
of the order of 100 psig.

You can estimate the required flow from the utility matrix prepared by 
your design team. If other labs in the building need N2, please add 
their estimated usage to the flow.

LN2 tanks come in various volumes. The one I had at UPenn was 6,000 
gallons and come with two vaporizers that alternate on their roles of 
generating gaseous N2. At UDel I have two 3,000 gallons tanks, each with 
two alternating vaporizers. At both UPenn and UDel, the tank(s) feed 
both the cleanroom and the research labs in the building.

To avoid major issues with ice on the vaporizers, please try to avoid 
having the LN2 tank(s) and vaporizer(s) on the North side of the building.


Cheers,

Iulian
