Storage Tank

Storage tank for liquified nitrogen located in Japan (client confidential)

INFORMATION STORAGE TANK

Shape: Φ1,500 x h, 4,130mm
Maximum storage capacity: 2,483 kg (internal volume: 3,414 L)
Cold insulation material: perlite grain
Cold insulation thickness: 140mm

METHOD
Comparing the surface temperature of the storage tank with liquid nitrogen and the production loss due to the heat of the sunlight before and after the application of Adgreencoat®. The heat from sunlight was measured at 8 points on the storage tank: 4 on the south side and 4 on the north side of the tank. The production loss due to the heat from the sun was measured via the boil-off gas (BOG) quantity.

DECREASE IN SURFACE TEMPERATURE

South side: lateral -3.8 ~ -4.5°C, canopy -10°C
North side: lateral -1.9 ~ -2.8 °C, canopy -7.4°C

REDUCTION OF PRODUCTION LOSS (BOG-AMOUNT)

LN2-BOG quantity per day: 12 kg less loss of production
LN2-BOG quantity per month: 359,4 kg less loss of production
Reduction of production loss: 21%
Savings per month: ¥ 40,253 | € 338.45
