Undergrpund LPG propane gas storage tank advantage

Underground tan have ow solvent evaporation loss feature, According to the total amount of storage in 500 ~ 1000 Cubic meters of stationary underground LPG gas tank farm. Due to the presence of soil, heat capacity is much larger than air, in the peak of summer when the hottest time, the heat on the ground can not be quickly transferred to the deep layer of the soil, but only slowly downward transfer. Take Shanghai as an example, the average temperature in July shadow 378 90 ground 708 India is 24919 1.6 m . At 20.606.53.2m, the F drops to 169 C% when the ground temperature is the highest, the underground is still at a lower temperature, at this temperature, the evaporation loss of solvent in the underground storage tank is very small. Therefore, compared with above-ground storage tanks, underground storage tanks reduce the investment in facilities such as spray cooling of the outside wall of the tank and condensation recovery of volatile solvents.
