Vent Size Package described

When a runaway reaction occurs within a reactor vessel, two-phase flow should be expected during the relief process. The vent sizing package (VSP) laboratory apparatus described in chapter 8 provides the much needed temperature and pressure rise data for relief area sizing. 

The Reactive System Screening Tool (RSST) was described in Section 33.2.7. This apparatus is a relatively recent development. Therefore, only limited literature data are available regarding the application of results from this equipment for direct scale-up of reactor systems. The Vent Size Package (VSP) is discussed further in Section 3.3.2.6. 

The Vent Size Package (VSP) apparatus was described in Section 3.3.2.6. The relatively small 100-cm3 test cell size implies that the samples tested may not be fully representative of commercial scale systems in some cases. The contents of the test vessel may be stirred, although the stirring facilities are not...
