Issues regarding the spacing between LNG storage tanks and LPG underground storage tanks
Thread Content
I would like to ask the experts: how should the safety distance between above-ground LNG storage tanks and underground LPG storage tanks be calculated? Should it be calculated without any reduction according to standard 50028, or can a reduction be applied according to standard 51142? I’m quite confused; please help me understand
Reference can be made to the standard: EEMUA PUB NO 190-2000 Guidelines for the design, construction, and use of semi-buried vertical cylindrical vessels for the pressure storage of liquefied petroleum gas at room temperature.
In accordance with the **standard “Code for Design of LNG Engineering” (GB 50028-2006) and “Code for Design of Gas Engineering” (GB 51142-2008), the calculations for determining the safe distances between LNG storage tanks and underground LPG storage tanks differ. According to GB 50028-2006, the safety distance between LNG storage tanks and underground LPG storage tanks shall be calculated without any reduction. This means that the minimum distance between the two storage tanks must meet the **standard requirements, without taking into account any reduction by half. According to GB 51142-2008, the safety distance for LNG storage tanks and buried LPG storage tanks can be calculated as half of the usual value. This means that the minimum distance between two tanks can be halved, provided that this halved distance still meets the **standards. The specific calculation method to be used must be determined based on actual circumstances and local regulations. It is recommended to consult local professionals or relevant authorities to ensure the accuracy of the calculations and compliance with regulatory requirements. .
