Understanding the provisions of GB50489 \"Code for General Layout and Transportation Design of Chemical Enterprises\"

Thread Content

Dear maritime professionals, Table 5.3.3 of GB50489, the \"Code for General Layout and Transportation Design of Chemical Enterprises\", specifies the minimum horizontal distance between mechanically ventilated cooling towers and adjacent buildings and structures; the distance from such towers to roads outside the site is 35 meters. What I would like to ask is that wet air cooling is currently widely used in chemical processing plants. In terms of its nature, it is similar to mechanical ventilation cooling towers. However, according to GB50160 \"Code for Fire Protection Design of Petrochemical Enterprises\", even if it is classified as a Class A process facility, the required spacing between such facilities is only 20 meters (and even on highways and first-class roads, it is only 30 meters). There is a significant difference here. I wonder how experts handle this situation in actual design work?
