Issues regarding the safety spacing in light hydrocarbon storage areas
Thread Content
I encountered a project that features two 49 m3 light hydrocarbon oil storage tanks; the liquid in these tanks is vaporized and used as fuel for boilers. Its main component is n-pentane, and its fire classification is Class A. Is it appropriate to use petrochemical regulations as the basis for design? If designed in accordance with petrochemical standards, are there any distance requirements between the unloading point and the gasification unit? What is the required distance between the gasification unit and the existing Class A buildings in the plant area? Is the distance between the gasification unit and the enclosure set in accordance with the requirement of 25 meters for Class A units? I haven’t worked on projects of this kind before, nor am I very familiar with petrochemical regulations; could someone help answer these questions? Thank you
According to the petrochemical regulations, process units must be located 25 meters away from the perimeter walls. Do units such as gasifiers and separation tanks (10 m3 capacity, handling gas-liquid mixtures) fall under the category of Class A units?
For n-pentane, it should be a Class A facility
Is a unloading point considered to be part of a vehicle loading and unloading station? In this layout, the distance between Class A equipment and the unloading point is also 25 meters. Are the requirements for such small tank areas really that strict?
What kind of factory is this? It’s hard to tell without a floor plan. Is the C5 tank the one with such a small volume; it’s one of the tanks in the facility, right? Is the vaporizer placed inside the device? In a process unit, the spacing can be calculated according to Table 5.2.1 of the petrochemical regulations. If they are separated into independent process units, the spacing shall be calculated according to Table 4.2.12. With such a small scale of operation, it’s not cost-effective to use formula 4.2.12.
It is a company that produces non-ferrous metals; it now needs to send the material to the storage tank area for use as fuel in boilers
