How should clause 5.2.22 of the petrochemical regulations be understood – namely that if the total volume of flammable liquids in the storage tanks of a facility is less than 1,000 cubic meters, such tanks can be located within the facility? 1. Several small tanks for flammable liquids (1 tank of 30 cubic meters each), with a total volume of around 300 cubic meters and less than 1000 cubic meters – can they be installed within the facility? Is it possible to arrange these storage tanks without following the spacing requirements specified in Table 5.2.1? 2. If the total volume of several storage tanks exceeds 1,000 cubic meters, they must be arranged in groups at the edge of the facility according to the regulations. Is it only when the total volume exceeds 1,000 cubic meters that they are considered a group of storage tanks for the facility, and are the distance requirements between these tanks specified in Chapter 6?
First, use the total volume to determine whether it can be placed inside the unit. If the total volume exceeds 1,000, it cannot be placed in the unit; instead, it must become a tank farm, which then falls under the category of utility storage and transportation tank farms. The fire separation distances between the tank groups within the facility are all in accordance with Chapter 6.
Should a total volume of no more than 1,000 cubic meters also be considered as a plant tank assembly? Should the fire separation distance between storage tanks also refer to Chapter 6?
Can several storage tanks be considered as individual tank units with a capacity of no more than 1,000 cubic meters each? It’s not necessary to consider it as a set of storage tanks, right? If the storage tanks of a unit are 1000 cubic meters or less, they can be placed within that unit; it isn’t specified how many there should be, so I can have multiple storage tanks for the same unit. However, when the volume exceeds 1000 cubic meters, the regulations require that the tanks be arranged in groups, and in that case they must be considered as a tank group. Is my understanding correct?
I have 10 methanol tanks, each with a capacity of 30 cubic meters; the total volume is less than 300 cubic meters, and it does not exceed 1000 cubic meters. Can I consider all 10 tanks as storage tanks for the facility? It can be placed inside the device, right, and there’s no need to follow Chapter 6? My understanding is that only tanks with a capacity of over 1,000 cubic meters are classified as plant tank groups and are subject to Chapter 6, right?
Yes, the jar is very small; just consider it as a container for the device.
According to the regulations: when the total volume of the storage tanks in the facility is such that the volume of liquefied hydrocarbon tanks is less than or equal to 100 m3, and the volume of tanks for flammable gases or liquids is less than or equal to 1000 m3, these tanks can be located within the facility. The fire separation distance between the storage tanks and other equipment and buildings must be no less than the values specified in Table 5.2.1. 1. Methanol is a flammable liquid; for tanks with a capacity of less than 1000 m3, the methanol tanks can be located within the facility, and the fire separation distances shall be in accordance with Table 5.2.1. 2. If there is sufficient space at the plant site, it is recommended to design it as a group of storage tanks, located at the edge of the plant.
The key point is that there are 10 methanol tanks, each with a capacity of 30 cubic meters; the total volume thus does not exceed 1000 cubic meters. All of these 10 tanks can be considered as storage tanks for the facility. According to Table 5.2.1, isn’t there any requirement for spacing between storage tanks? Only when the area exceeds 1,000 square meters can it be considered a tank group; only then must the spacing requirements between tanks as specified in Chapter 6 be followed, right?
1. The regulations are clear: when the volume of a single tank containing flammable liquids is 1000 m3 or less, it can be located within the facility. For systems with a total volume greater than 1000 m3 and less than 5000 m3, it is necessary to have a group of storage tanks for the facility, which should be arranged at the edge of the facility. In other words, these methanol tanks (V
The large number of storage tanks is required by the process; they cannot be combined
The 9th floor is the correct answer. What you wrote in 5.2.22 isn’t in line with the standards, and its meaning is also incorrect. It is recommended to treat this as a separate tank farm; safety assessment experts are very likely to consider all these tanks as part of a tank farm, requiring a dedicated area for them
