API PUBL 2510A
Fire-Protection Considerations for the Design and Operation of Liquefied Petroleum Gas (LPG) Storage Facilities
|Publication Date:||1 December 1996|
This publication addresses the design, operation, and maintenance of LPG storage facilities from the standpoints of prevention and control of releases, Þre protection design, and Þre-control measures. The history of LPG storage facility failure, facility design philosophy, operating and maintenance procedures, and various Þre protection and ÞreÞghting approaches are presented. This publication, since it supplements API Standard 2510 and provides the basis for many of the requirements stated in that standard, must be used in conjunction with API Standard 2510. In case of conßict, API Standard 2510 shall prevail. Alternate designs are acceptable provided equal safety can be demonstrated.
The storage facilities covered by this publication are LPG installations (storage vessels and associated loading/ unloading/transfer systems) at marine and pipeline terminals, natural gas processing plants, reÞneries, petrochemical plants, and tank farms. The following types of LPG installations are not addressed
a. Underground storage, such as buried tanks, storage caverns, salt domes, or wells.
b. Mounded storage tanks.
c. Refrigerated storage at pressures below 15 pounds per square inch gauge.
d. Installations covered by API Standard 2508.
e. Installations covered by NFPA Standards 58 or 59.
f. Department of Transportation (DOT) containers.
g. Those portions of LPG systems covered by NFPA 54 (ASME Z223.1).
h. Small installations with a single LPG tank of less than 2000-gallon capacity.
i. Process equipment for LPG manufacture or treatment preceding LPG storage.
