Saw a thread about what everyone does for a job and i thought i would post this, i don't think it's that interesting anymore as i do it quite often but my brother thought it was cool so i thought i'd post a few pics.

Liquid nitrogen tank



Cryogenic hoses (stainless steel)


Nitrogen pumping unit


Control panel


Boost pump and stainless pipwork


"pot" or heat exchanger, converts liquid nitrogen to gas


High pressure side, nitrogen gas comes out this pipework, job done.

It is quite interesting though mate

Still with Schlum then Rog?

It's Czech Mate

Yeah i worked with it at Nestle when I made Icecream, got burns on my face and eyelid when some of the cooling tunnels broke!!!!!!!

whats it used for?

St3V3_C

If I understand, this kit above is used to turn the liquid into gas.

The gas is used for:

Nitrogen gas, N2, is produced by allowing liquid nitrogen, N2(l) (see below) to warm and evaporate. It has a wide variety of applications, including serving as a more inert replacement for air where oxidation is undesirable;

to preserve the freshness of packaged or bulk foods (by delaying rancidity and other forms of oxidative damage)
on top of liquid explosives for safety
in the production of electronic parts such as transistors, diodes, and integrated circuits
dried and pressurized, as a dielectric gas for high voltage equipment
in the manufacture of stainless steel
for filling automotive and aircraft tires[1] due to its inertness and lack of moisture or oxidative qualities, as opposed to air (though this is not necessary for consumer automobiles [2])

We use Liquid nitrogen at work. Like Rogers it converted into Gas using heat/steam...

It's is pumped into our massive vessels and is known as a 'Purge'...

The nitrogen is forced into the vessels to remove any Oxygen... This prevents any ignition in the vessel when loading flammable liquids/resins. Reason why it's done is that nitrogen in a gas form is not flammable

Nice thread Roger, interesting pictures What pressure does it run at?

Dare you to stick your tounge on that!!! and take photo lol

Nah i think i'll give it a miss Lol........

Toughy, yeah decided to stay after all, got a really good deal money wise out of it, but still thinking of moving on in the next few months, just got home yesterday.
In this case it's mainly used for what is called "gas lifting" of wells offshore, i.e displacing fliud in the well to nitrogen, basically flushing all the fluid out to encourage the well to flow, due to the Nitrogen gas being lighter than a column of fluid.
Smit, the liquid N2 tanks use are normally operated to about 2bar and can go upto about 5, but you never have them up that high, you do get higher pressure ones though. The output line in red and white can be anything upto 15,000 psi.

The what???? you missed a word out

i know a funny story about that we use it at work for many things,, we store it in big vessels which need to be topped up! so when the top of wagon comes, we gotta go up there and knock the ice from the topup valve, and my friend stuck his hand on it

Gareth did he lose the skin on his hand?

Smit

I wouldn't be surprised if he actually burnt his skin off on his hand

Roger - We don't deal with massive pressures, usually between 3-10 BAR

GARETH T

he just pulled it off,,, and it was fine,, he did shit for a min though
