This document specifies the sizing of safety valves and rupture discs for two-phase gas/liquid flow in pressure systems such as reactors, storage tanks, columns, heat exchangers, piping systems or tanks/transport containers, see Figure 2. Possible fluid states at the safety device inlet which may result in two-phase flow are given in Table 1. NOTE In this document, pressures are expressed as absolute pressure , and not in gauge pressure.
