Understanding process units in petroleum refining regulations
Thread Content
Dear sea friends, according to GB50160, the fire protection distance between process units (Class A) is 30 meters. So what exactly does \"process unit\" refer to in this context? Is it a work section? Is it still a set of devices? For example, there is currently a set of ammonia synthesis production facilities, which include tank areas, synthesis sections, compression sections, and decarburization sections. Are these sections considered process units? Still, the ammonia synthesis plant is a process unit
Terms 2.0.10–2.0.13 of GB50160 contain definitions of nouns； Areas with devices that are interconnected upstream and downstream and are not far apart are generally referred to as integrated facilities ； The spacing requirements shall be determined with reference to Table 5.2.1 ； Table 4.2.12 is the overall layout diagram of the facilities within the plant, showing the spacing requirements for the various areas based on their functional purposes. Thank you!
Your tank area is definitely independent； Synthesis, compression, and decarburization – these need to be carefully examined in light of the actual process relationships and relevant standards to determine how to distinguish between them
