Sizing methods for bottom relief dumping of gassy reactions

5 SIZING METHODS FOR BOTTOM RELIEF (DUMPING) OF GASSY REACTIONS 

The Boyle method (see A5.13) can be used to estimate the diameter required for a dump system. It will usually be safe to assume liquid-only flow if dumping occurs well before the maximum rate (the original Boyle method). Alternatively, the conservative assumption that a homogeneous two-phase mixture (rather than liquid alone) enters the dump system from the reactor could be made (the modified Boyle method).
