For 10-class flammable liquid storage tanks, it is necessary to keep the storage temperature below 20 degrees. What measures can be taken in summer to ensure this? Is it okay to use water for spraying? Should the water be pumped out or used for internal spraying circulation? What’s the price to seal it with colored steel plates and install air conditioning? Use a fan to cool it down? Wrap it in thermal insulation material?
Insulation is necessary; to reduce temperature, an external chilled water jacket can be used, or the liquid inside the storage tank can be circulated and cooled with chilled water
I don’t know what the temperature of your incoming material is, nor what the specific physical properties of the flammable liquid are. All the methods you mentioned are good; it’s just a matter of whether they are suitable or not. For ordinary Class A tanks, we just apply some cooling adhesive to our toluene storage tanks.
““Ensuring that the storage temperature remains below 20 degrees” – is this the only solution? For example, improving the pressure resistance of the containers so that they can withstand normal room temperatures. In the case of the toxic liquefied gas MIC storage tanks involved in the Bhopal accident in India, a cooling system was installed to keep the temperature below 12 degrees. In fact, even if this temperature is not maintained and the pressure becomes slightly higher, it is still sufficient to meet safety requirements; therefore, the refrigeration system was shut down and no longer maintained. As a result, when the temperature rose abnormally, it became impossible to activate the refrigerant, and dozens of tons of it were released into the atmosphere, causing tens of thousands of people in the city to die
A liquid ammonia pipe has an inlet and an outlet; a U-shaped component is inserted at the bottom of the tank. The inlet control valve regulates the amount of evaporation, while the outlet leads to the ammonia refrigeration compressor (of course, an ammonia refrigeration system is required). The storage tank is insulated to prevent heat loss.
Polyurethane insulation should be fine; the equipment needs external protection!
