Guide for Venting Atmospheric and Low-Pressure Storage Tanks - Second Edition
 N RP 2000

Annotation

This guide applies to the normal and emergency venting requirements for aboveground liquid petroleum storage tanks designed for operation from ? oz per sq in. vacuum through 15 psig pressure.

This guide outlines safe and reasonable practices for the normal temperate-zone climate and normal operating conditions. The many abnormal variables which must be considered in connection with tank-venting problems make it impracticable to set forth definite simple rules which are applicable to all locations and all conditions. Larger vents may be required on tanks in which oil is heated, on tanks which receive oil from wells or traps, and on tanks subjected to pipeline surges, Similarly, the use of flame arresters or other restrictions, which may build up pressure under certain conditions, may build up pressure under certain conditions, may require the use of larger vents on tanks.

The requirements of this guide do not apply to floating-root or lifter-roof tanks.
