2015 Spring Meeting and 11th Global Congress on Process Safety

October 28 - November 2, 2012

ASME and API have established maintaining the inlet pressure drop for a relief valve below 3% of the set pressure as the criteria for ensuring stable valve function. Recent investigations have indicated that relief valve stability is a more complex phenomenon than previously thought. This session invites original papers that present the results of research and investigations of relief valve stability as well as those that offer practical approaches of evaluating this important criterion of relief system design. Another critical area of relief design that can be overlooked but can have significant impact on the safety of a relief system is the stress placed on relief piping due to reaction forces. Papers which address this consideration will also be entertained.
