n2 BLANKET
n2 BLANKET
(OP)
We are planning to load Hopper Railcars with Bisphenol A and adding n2 nitrogen as a blanket. Any ideas on how? Our laoding method is from super sacks to a agriculture type conveyor tube to top of railcar manhole. Suggestion on applying this idea? This is all new to us.





RE: n2 BLANKET
Not sure how you load this stuff, but if you can't seal the inlet point then it won't work or you will loose large quantities of N2.
Usually you add a gas supply to some very low pressures ( inches water guage) with suitable venting arrangement as the tank fills up. This requires a secondary nozzle on top of the vessel.
Adding the blanket after loading really requires inlet and vent nozzles either end of the railcar to sweep the gas space free of oxygen.

Nitrogen can kill in confined spaces so the venting needs to be controlled properly. How you get a controlled supply and vent system onto a railcar is beyond me...
Or why.

A chemical car (used for vaporous or flammable liquids) would have a sealing hatch.

Just curious to know the use of Bisphenol A ?
I thought this chemical was recognized by many countries risk for public safety. This includes concerns raised by World Health Organization.
