API STD 2510 For Petroleum Refining Standards
This standard covers the design, construction, and location of liquefied petroleum gas (LPG) installations at marine and pipeline terminals, natural gas processing plants, refineries, petrochemical plants, or tank farms. This standard covers storage vessels, loading and unloading systems, piping, or and related equipment.
1.1 The size and type of the installation; the related facilities on the site; the commercial, industrial, and residential population density in the surrounding area; the terrain and climate conditions; and the type of LPG handled shall be considered. Generally speaking, the larger the installation and the greater the population density of the surrounding area, the more stringent are the design requirements.
1.2 Design and construction considerations peculiar to refrigerated storage, including autorefrigerated storage, are covered in Section 9 of this standard.
1.3 In this standard, numerical values are presented with U.S. customary units only. These U.S. customary values are to be regarded as the standard values.
1.4 This standard shall not apply to the design, construction, or relocation of frozen earth pits, underground storage caverns or wells, underground or mounded storage tanks, and aboveground concrete storage tanks.
1.5 This standard does not apply to the following installations:
- Those covered by NFPA 58 and NFPA 59.
- U.S. Department of Transportation (DOT) containers.
- Gas utility company facilities; refinery process equipment; refinery and gas plant processing equipment; and transfer systems from process equipment upstream LPG storage.
- Those tanks with less than 2000 gallons of storage capacity.
The provisions of this standard are intended for application to new installations. This standard can be used to review and evaluate existing storage facilities. However, the feasibility of applying this standard to facilities, equipment, structures, or installations that were already in place or that were in the process of construction or installation before the date of this publication, must be evaluated on a case-by-case basis considering individual circumstances and sites.
1.7 Characteristics of LPG
LPG is customarily handled in a liquid state achieved by its liquefaction under moderate pressure. Upon release of the pressure, LPG is readily converted into the gaseous phase at normal ambient temperature.
The safety of LPG storage installations is enhanced by the employment of good engineering practices, such as those recommended by this standard, during design and construction.
