Discussion on the safety distance between heating furnaces and reactors
Thread Content
Hello everyone! Standard GB 50160 specifies that there is no requirement for a fire separation distance between the heating furnaces for reactions such as hydrocracking and hydrorefining and the reactors. So, if a unit has both hydrorefining (F-101 and R-101) and hydrocracking (F-102 and R-102), with no specified safety distance required between F-101 and R-101 nor between F-102 and R-102, is there then any restriction on the safety distance between F-101 and R-102, or between F-102 and R-101? Standard SH 3011 specifies that the distance between the reactor and the heating furnace should be no less than 4.5 meters, which is generally sufficient. The requirement is that there should be a 15-meter distance between the heating furnace and Class A flammable gas equipment; since hydrogen is present in hydrogenation processes, is it necessary to maintain a 15-meter distance between F-101 and R-102 as well? If the land to be acquired is large enough, there will be no problems; everything can be based on a width of 15 meters, and that will definitely work fine.
Interesting~~~ If it’s a workshop, then it should be set up according to the attached diagram； If it are two workshops, then according to Table 4.2.12 of GB50016, the distance between Class A workshops should be ~30 meters~~
What we do now is generally arrange them with a spacing of 15 meters between the F-101 and R-102
