Stability Analysis of Safety Valve

Mar 22, 2010
The stability for a safety valve was investigated by experiments and analysis. It was found that the dynamic instability was caused by the interaction effect between the pressure wave propagation through the inlet pipe and the valve disc motion. This dynamic instability is mitigated by the...

Results of Root Cause Analyses of Spring Operated Pressure Relief Valve Failures

Mar 22, 2010
Julia V. Bukowski
A subset of 44 failed spring operated pressure relief valves (SORV) from a set of over 5600 Process Equipment Reliability Database (PERD) proof tests was subjected to root cause of failure analysis (RCA). This paper reports on the findings of those 44 analyses and includes specific examples of root...

Process Safety in the Face of Significant Change

Development of an effective process safety culture requires employees to look beyond intended performance, to their own nonconscious assumptions about process safety. When firmly in place, effective process safety culture instills an environment where employees differentiate between events which,...

Strategies & Tactics for Mechanical Integrity Budget Battles

Daniel A. Long
Effective mechanical integrity programs are essential to assure safe operation of plant facilities. The current economic downturn is difficult and most manufacturing companies have experienced headcount reductions, early retirement programs and budget reductions. Companies are concerned with short...

Utilizing Integrated Risk Assessment to Maximize Asset Integrity Management

Mar 22, 2010
Steve Soos
The advent of various safety standards like ANSI /ISA 84, IEC 61511, API 14C, API 580 / 581, SAE JA1011, IEC 60330 and PSM guidelines has been a good impetus in improving the availability and reliability of safety systems and processes with an objective to meet the requirements defined by OSHA, EPA...

High Integrity Protective System Design Using a Risk Based Approach

Mar 22, 2010
Robert J. Stack
With the update of the High Integrity Protective System (HIPS) methodology by API in 2007, Dow Chemical updated its internal work process to apply Dow's risk based work processes to HIPS design, application and evaluation. Rather than just focusing on the vessel related consequences of substituting...

Chronic Pain Resulting from Your Relief Device Management Systems

David A. Moore
With the increasing use of Layer of Protection Analysis as a semi-quantitative method of assessing process risk, LOPA practitioners are asked to assign credit to numerous safeguards including relief devices. Relief devices are only as strong as the initial design of the component and the systems...

A Guide to Developing and Implementing Safety Checklists: Plant Steam Utilities

Mar 21, 2010
Delmar Morrison
Steam generation is an integral part of most chemical process plants; however, the steam plant often is or can be overlooked in the area of hazard analysis. The reasons for this oversight are obvious: steam generation is considered to be an old and well understood process, and steam boiler systems...

Training Management of Change Approvers

Mar 21, 2010
Karen Study
Many companies have made great strides in change management systems since OSHA's Process Safety Management Standard 29 CFR 1910.119 was first promulgated in 1992. This standard required “implementation of written procedures to manage changes… that affect a covered process”i. Although significant...

Managing Management of Change

Mar 21, 2010
Jack Chosnek
The Center for Chemical Process Safety (CCPS) has designated MOC as one of the areas where metrics need to be developed. One of the issues that CCPS is concerned about is the quality of the MOCs as much as the quantity of those that have not been completed. One of the reasons is that people tend to...
