Are spherical tanks filled with high-pressure nitrogen for displacement?
Thread Content
Dear sea friends, has anyone tried to replace the ball tank directly with high-pressure nitrogen?
How can it be purged using high-pressure nitrogen? Can it be purged completely? Replace it with water? No
Spherical tanks are used for hydraulic testing, but water is not used to displace air; nitrogen is generally used for such displacement. The key is that the nitrogen pressure is a bit high
It should be possible, but our ball tanks are purged with high-pressure nitrogen; however, pressure testing with water has not been done.
How much high-pressure nitrogen do you have? Is it injected directly into the spherical tank at high pressure, or is it fed in after the pressure is reduced?
Replacing with nitrogen works well.
Ethylene tank, propylene tank. Reduce the pressure to 4.0 using 8.0 MPa; after entering the tank, maintain a pressure of 2.0 MPa
I have seen ball tanks be purged with nitrogen at a maximum pressure of 4.0 Mpa, with gas being introduced while also being removed, in order to control the pressure of the nitrogen used for purification.
Charge while discharging? Isn’t that quite a waste?
