Tracing the accuracy of calibration gases
Calibrating your instruments using specialty gas will only yield results as accurate as your gas mixture. This three-page white paper discusses analytic traceability and how it relates to gas mixture accuracy.
Continuous PHA Revalidation
A process hazard analysis must be revalidated every five years. This paper discusses the merits of a new approach aimed at increasing the effectiveness of PHAs, called Continuous PHA revalidation.
Facility Major Risk Survey
This 8-page primer describes a method for identification of major acute risks in existing process facilities that can potentially affect on-site and off-site populations and for prioritization of mitigation methods.
Relief Design for Reactive Systems Get the Facts
This 15-page paper focuses on the additional degrees of complexity that reactive systems pose for emergency relief systems. It covers topics such as how to screen for reactivity and what practices, standards and regulations should be followed, as well as a host of other issues.
Ziegler-Nichols Tuning Rules And Limitations
The standard reference for PID tuning seems to be the Ziegler-Nichols tuning rules developed in 1942 on a pneumatic controller. Here is how to tune a controller using these rules.
Why Process Safety Management Audits Fail
Most companies have completed at least three process safety management(PSM) compliance audits of their covered facilities since the promulgation of the OSHA PSM standard. These companies, however, are not seeing noticeable improvements in their PSM programs. In fact, many companies feel that their PSM programs have become less effective. What has happened and why? Are there any lessons learned from the Enron collapse and its auditing program? What needs to be done?
