What are the storage requirements for o-xylene?
Thread Content
What are the physical and chemical properties of o-xylene? What are the requirements for the tank in which it is stored? What should be noted in terms of operation?
The flash point of o-xylene is 30, and it is a flammable liquid with a high flash point; it should be stored in a cool, well-ventilated warehouse. Keep away from flames and heat sources. The storage temperature should not exceed 30°C. Keep the container sealed. It should be stored separately from oxidizers; mixed storage is strictly prohibited. Use explosion-proof lighting and ventilation facilities. The use of mechanical equipment and tools that may generate sparks is prohibited. The storage area should be equipped with emergency response equipment for leaks and appropriate containment materials.
Can atmospheric pressure vertical cylindrical steel storage tanks (interior floating roof tanks) be used for storage? Is it corrosive to pipelines?
Density (20°C), neutral test, appearance, pickling colorimetry in g/l, non-aromatic content % ≤ 1.0; ethylbenzene % (m/m), p-xylene % (m/m); m-xylene % ≤ 1.5; isopropylbenzene; o-xylene % ≥ 97. Product specifications – no insulation required for the tank
I now know the physical and chemical properties; what are the requirements for storage tanks (in terms of processes and equipment)? Is it corrosive to pipelines? We use vertical cylindrical internal floating roof tanks here – can it be stored in them?
Carbon steel pipeline valves will do; our facility also has floating roof tanks.
So, what this sea friend is suggesting is that vertical floating roof tanks can be used for storage? The storage of o-xylene requires high levels of containment for the storage tanks; what considerations should be taken if floating roof tanks are used for storage?
Why isn’t anyone answering? Please, that expert, give me some clear guidance.
Our facility uses vertical dome tanks equipped with breather valves.
O-xylene can be stored in internal floating roof tanks (whose fire hazard classification is Class A B). Additionally, o-xylene is of low toxicity, and the exhaust gases must be recovered. Furthermore, according to the Code for Design of Industrial Metal Piping, the flange class for o-xylene must not be lower than 20 kilograms
