Regulator for Liquid Nitrogen
Regulator for Liquid Nitrogen
(OP)
I need advice how to supply Liquid Nitrogen from Storage Tank (press 5 barg) to dose machine with pressure max 2barg, through pipeline Vacuum Jacket Line 1", length 31m.
I can't make tank pressure lower to 2 barg, because Liquid Nitrogen will be change phase to vapour. should i use Regulator Liquid Nitrogen ? Does any one have information about Regulator for Liquid Nitrogen ?

Look into LN freezer temperature regulation.

"I can't make tank pressure lower to 2 barg, because Liquid Nitrogen will be change phase to vapour" implies that you're keeping the main tank under pressure in order to allow the temperature to rise to above -196??
If you're going down to 2 barg with liquid N2 which is at a higher temperature than it should be to remain liquid at 2 barg then you won't have liquid N2 anymore and a lot more problems than simply moving a very cold liquid about.
Please explain.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I have installed Nitrogen Liquid Regulator near the dose machine, with tank setting pressure until 3-4 Bar. Without Regulator with the pressure tank 3-4 Bar then liquid nitrogen still can reach until the end of VJ Line, but output the regulator is vapour/not liquid if setting pressure regulator is 2 bar.

EdStainless, thanks for your advice, do you have sample P&ID or drawing installation ? installation sequences after the tank is Control Valve and then Regulator ? Control Valve and Regulator shoul be near the dose machine ?
