Experts, I would like to ask whether benzene and styrene storage tanks can be placed within a fire dike
Thread Content
Dear experts, I would like to ask whether 2 benzene storage tanks with a capacity of 5,000 m3 each can be placed in the same tank area as 2 styrene storage tanks with a capacity of 5,000 cubic meters each. According to Article 3.2.1, Clause 7 of standard GB50351-2014, “Storage tanks for liquids of Class I and Class II toxicity should not be located in the same fire protection zone as other storage tanks for flammable and combustible liquids.” However, the petrochemical standard GB50160-2008 (2018 edition) does not address this issue. Since there are also many existing storage tanks involved, implementing GB50351 requirements would involve significant work. Could any expert determine whether benzene and styrene can be placed in the same fire protection zone? Any relevant standards would be greatly appreciated. I’m also very grateful for the other comments; thank you
Neither benzene nor styrene belongs to the category of toxic substances of Grades I and II, right?
Just put it in a tank group, separate it with dikes so that it’s no longer within a single fire dike, that’s all~~
Separate fire dikes for Class I and Class II toxic liquids
A separate fire dike can be installed within the same tank group
Benzene is extremely hazardous, while styrene is moderately hazardous; according to the specifications for fire dike design, separate and independent fire dikes are required. This is also specified in the new standards for fine chemicals
According to Clause 5.1.6 of the Oil Storage Tank Code, storage tank areas should be designated separately for tanks holding liquids with toxicity levels 1 and 2.
