Xylene storage tank
Thread Content
Xylene storage tank: 15 cubic meters, vertical design with a dome shape; sealed with nitrogen along with a vent valve. The excess gas is released directly into the atmosphere. The tank is made of stainless steel; no insulation is provided. It is located outdoors and lacks any temperature control mechanism. Temperatures can exceed 40 degrees in summer – is it necessary to use water spraying for cooling? Those with experience in this area please advise
There is no need; water spray systems are commonly used in the LPG industry
Insulation and heating are necessary; the freezing point of xylene is around 13 degrees, so spraying is not required after insulation.
Xylenes refer to mixtures of o-xylene and m-xylene; their freezing point is well below 0 degrees, so no heating is required. As for measures to prevent static electricity: 1. The feed inlet of the storage tank should be located below the liquid level. 2. All pipes and equipment must be equipped with static electricity grounding. Are there any other measures? Is it necessary to control the flow rate? How to control it?
Like the paraxylene storage tanks we use in the south, they generally do not require heating, insulation, or spraying. The freezing point of xylene is -34℃
Xylene storage tanks do not require heating, insulation, or spraying; applying cooling insulating adhesive to the outer wall of the tank is sufficient.
Our company has dozens of xylene storage tanks, and we’ve never seen any with insulation. Carbon steel material will do!
Isn’t there any insulation in the north either? It would be best if everyone could mention the local temperature.
The PX storage tanks in Shandong need insulation coatings. . .
It should refer to mixed xylene! It has a very low melting point, so no insulation or heating is required. Para-xylene, on the other hand, does require such measures, as its melting point is only 13 degrees
No insulation is needed; CS material is sufficient.
