Can liquefied hydrocarbon chloromethane and propylene oxide be placed in the same tank farm?
Thread Content
May I ask: Can liquefied hydrocarbons such as chloromethane and propylene oxide (with a boiling point below 45 degrees) be stored in the same tank farm?
Sure, but for propylene oxide tanks, pressure tanks must be used. Someone has asked a similar question before. Propylene oxide is a Class A, Group M liquid with a boiling point below 45 degrees, so pressure or low-pressure storage tanks are suitable. Article 6.2.5, Paragraph 3 of the Petrochemical Regulations stipulates that pressure storage tanks for flammable liquids may be arranged in the same group as full-pressure tanks for liquefied hydrocarbons.
Try to place flammable liquids with similar fire ratings in the same tank group.
Kjar, no need to correct me; I’m not wrong. You didn’t read the specification provisions, did you? Hehe. You misunderstood me; it’s not the case that a liquid with a boiling point of less than 45°C is classified as a Class A or B liquid. The flash point of propylene oxide (open cup) is -37°C, and it is classified as Category A. Its boiling point is 33°C, which meets the requirement of a boiling point below 45°C.
