How to understand the storage tanks mentioned in GB50160, and how to determine the fire separation distances for these equipment during layout?

The last edit to this post was made by GHJDSM on 2011-4-10 at 07:54. GB50160 provides the following definition for storage tanks within a process plant: 2.0.18 Storage tanks (groups) within process plant – These are tanks (groups) that, during the normal operation of the plant, do not directly participate in the chemical processes; however, they are installed within the plant due to process requirements, such as the need to balance production, ensure product quality control, or facilitate initial investments. If the design of a fine chemical plant includes two 65-cubic-meter storage tanks for flammable liquids (containing different substances, both classified as Class A/B; they are neither raw materials nor products, but rather intermediate substances that can be reused), is it necessary to enclose these two tanks separately with fire dikes and keep them 9 meters away from the main plant building (which has an open reinforced concrete structure)? What does it mean not to be directly involved in the manufacturing process?
I’ll take over. If anyone knows, please help explain it. :time:
Participation in process engineering generally refers to components that are integrated into the process flow; for example, intermediate buffer tanks installed to ensure the continuous operation of pumps serve as buffers between different stages of the process and can be directly placed within the production facility. A notable feature of such components is their short storage time, which usually ranges from 8–10 minutes to a few hours. And some storage tanks, such as those used for batch production of products, are kept for a relatively long time ； And there are buffer tanks added to balance the two processes before and after; they are characterized by a longer storage time, ranging from a few hours to several days. However, these differ from the storage tanks for raw materials and products, and can be considered as storage tanks for the facility.
The buffer tanks added before and after the semi-finished product tank balancing process are characterized by a longer storage time, ranging from a few hours to several days. However, they differ from the tanks used for storing raw materials and products, and can be considered as storage tanks for the facility.
The layout of the intermediate storage tank shall be carried out in accordance with the provisions of Chapter 5 of GB50160. If the 65 m3 storage tank mentioned by the poster is located in the same area as the equipment, there are no restrictions on the distance between it and other devices’ firewalls (per GB50160 Table 5.2.1); it can be arranged according to the requirements of the operating space, while the distances between tanks should follow the provisions in Chapter 6, Table 6.2.8. If they are not in the same area, they must be arranged in accordance with the fire protection requirements for Class A storage tanks and buildings (as specified in Table 4.2.12 of GB50160).
