Regarding the cooling of propylene spheres
Thread Content
In summer, the temperatures are high; as a result, the temperature inside the propylene storage tanks is also high. The pressure in these tanks is high, so the fire suppression systems cannot remain activated for long periods. Do anyone have any good solutions?
Is there no exhaust pipeline between the spherical tank and the gas holder?
We don’t have gas tanks; we only have fire sprinklers. By the way, are there any other methods besides using gas tanks?
If the problem is severe, considering adding a pump and a heat exchanger, along with pipes for circulation, could be an option.
If the tank is relatively small, it is possible to install a condenser on its top, but since the spherical tank is quite large, this is not feasible.
It seems we can only add a heat exchanger or an ice machine
During the hot summer days, turn on the sprinklers for cooling; a few hours is enough
Spraying is the most cost-effective option; installing an ice maker or a vaporization-based heat-absorption compression condensation cycle is too expensive. Non-condensable gas can also be discharged in front of the refined propylene top cooler, but care must be taken to ensure that the vapor phase at the top of the refined propylene tower is not overloaded.
In summary, installing a spraying system is the simplest and most effective method for cooling down. However, fire suppression sprinklers and cooling sprinklers are two different types of systems. Cooling sprinklers use the latent heat of vaporization of water to lower the ambient temperature; they employ specialized nozzles to turn water into liquid droplets smaller than 20 microns, and these droplets vaporize easily, absorbing heat in the process and thereby reducing the ambient temperature, while also ensuring low water consumption
If the storage pressure of the propylene sphere tank is 1.7 MPA, then the condensation temperature of propylene is around 42 degrees； Under normal circumstances, even in summer, the pressure in propylene spheres does not rise too high. If the pressure is high, first take a sample to analyze the components of the gas phase inside the tank, to check whether the levels of carbon monoxide and carbon dioxide exceed the specified limits. If the components are of good quality and the ambient temperature is too high, appropriate spraying can be used to reduce the temperature.
