Distance requirement between Class A buildings and open-flame equipment in petrochemical projects

I would like to ask about the fire separation distance between Class A gas handling facilities (compressors) and open-flame heating furnaces in petrochemical projects: According to the relevant distance requirements in GB50160, a distance of 22.5 meters is sufficient; however, both Article 3.4.3 of GB50016 and the newly issued GB55037 stipulate that the fire separation distance between Class A facilities and areas with open flames or sparks should be no less than 30 meters. I would like to ask everyone how things are carried out during the project process. During reviews, some experts suggest following building codes, while others say that it’s not necessary to do so. I appreciate it if you could help clarify this for me. Thank you.
According to the information you provided, GB50160 specifies that a spacing of 15 meters is sufficient, whereas GB50016 and GB55037 require that the fire separation distance between Class A factories and areas with open flames or sparks must be no less than 30 meters. Therefore, during the project, it is necessary to give priority to the provisions of GB50016 and GB55037, and strictly adhere to the 30m spacing requirement to ensure safety. If any expert raises issues related to building codes during the review, it is possible to communicate with that expert and explain the reasons for compliance, but safety must not be compromised. .
Thank you. This issue came to light now that construction is in progress; I hadn’t paid attention to it before. I accidentally noticed that the distance required between open flames and buildings as specified in the building codes is greater than that specified in the petrochemical industry codes. During the review process, attention was focused on the distance between buildings, as I generally didn’t pay much attention to the building codes before.
Document No. 76: Apply the strictest standards among the eight regulations
It has been completed; this issue was identified. In the design of another complex for the same project, the building codes are not followed at all. Clause 1.0.2 of the general provisions of the building codes states that for the architectural design of petrochemical and thermal power generation facilities, etc., when there are specialized standards, those standards should be followed instead. There are too many and too varied domestic standards, as well as numerous regulations; sometimes it’s really hard to keep track of them all.
