7-64 There is a set of horizontal liquid ammonia storage tanks with a diameter of 1500 mm. Considering fire separation requirements, the appropriate distance between these tanks should be ( ). (1) 0.8 m (2) 1 m (3) 1.5 m (4) 2 m. No relevant provisions can be found in GB50160-2008. Please give me some guidance, master
Article 27 of Section 3, Chapter 2 of the \"Code Requirements for Liquid Ammonia Storage Tanks\" states that the fire separation distance between liquid ammonia storage tanks shall meet the following requirements: 1. The fire separation distance between horizontal tanks is generally 1.0 times the diameter of the tank, and should not exceed 1.5 m； 2. The fire separation distance between spherical tanks shall not be less than 0.5 times the diameter of the tanks when accidental emissions are directed to a flare or absorption treatment unit ； When there are no measures for emission to the flare without accidents, it should be not less than 1.0 times the diameter of the spherical tank ； 3. The fire separation distance between spherical tanks and horizontal tanks within the same tank group shall be the larger value ； 4. The distance between the two rows of horizontal tanks should not be less than 3 m ； 5. The distance between storage tanks in adjacent tank groups shall not be less than 16 m. Therefore, the answer to the previous question should be (3) 1.5 meters.
“1. The fire separation distance between horizontal tanks is generally 1.0 times the diameter of the horizontal tank, and should not exceed 1.5 m； ” Change to should not be less than
Liquid ammonia is a flammable liquid; its fire hazard classification is Category B. Table 6.2.8 of GB50160-2008 specifies that the spacing between horizontal tanks should be 0.8 meters
According to Section 6.3.3 of the Petrochemical Regulations, the fire separation distance requirements for liquid ammonia storage tanks should be the same as those for liquefied hydrocarbon tanks; for horizontal tanks, this distance is 1.0D
