PRESSURE RELIEF AND TWO-PHASE FLOW
By S. Selmer-Olsen
Pressure relief systems have traditionally been sized assuming that
vapour only will be vented. However* there is a growing awareness that
this assumption leads to inadequate pressure relief in the likely event of
gas/liquid mixture venting. Frequently used design recommendations
like API 520 and 521 are not updated on these aspects* and the
recommendations are by many regarded as obsolete and potentially
leading to undersizing. The paper discusses available recommendations*
also in light of own recent findings.
