...many operating companies are mobilizing to increase their facility's charge rates. If you are one of these companies looking for improvements, correctly evaluating your flare system's maximum capacity could "make or break" your project's feasibility studies.
Smith & Burgess is excited to announce our recent partnership with the Houston Chapter of "Society of Women Engineers."
The Society of Women Engineers, also known as SWE, is an inclusive organization focused on issues of interest to women specializing in engineering and technical careers. The SWE Houston Area Chapter is the fourth largest chapter in the Nation with almost 700 members.

A major United States refinery, with a significantly high Nelson Complexity Index rating, had nine flare stacks and multiple engineering contractors working within the facility which made managing their flare design and documentation a challenge.
A major United States refinery was in the process of installing a site-wide rate increase and hired a competing engineering firm to perform the feasibility study. The engineering firm sized their crude fractionator and recommended new relief devices that would require modifications to their existing flare header. The refinery’s corporate office called Smith & Burgess and asked us to perform a third-party review on the engineering firm’s recommendations.
Anyone tasked to start up a unit knows the engineers who designed it rarely miss a thing...
Every bleeder valve is in the right place, spectacle blind turned correctly, and bypass line scrutinized. So why would the flare and relief systems design be any different? The truth is that they are not. Engineering Firms today have perfected the art of throwing waves of engineers on design-build projects. Unfortunately for those engineers, relief and flare system designs are governed by a maze of regulations, codes, standards, and guidelines (collectively known as Recognized and Generally Accepted Good Engineering Practice or RAGAGEP). Experienced Project Managers understand that relief and flare specialists are needed to ensure their projects are safely and properly designed before any construction occurs.

Ms. Mueller is a graduate from the University of Missouri with a degree in Chemical Engineering. She has extensive experience with Relief Systems and Flare Design projects. Over the past three years, Amanda has been an invaluable addition to Smith & Burgess' engineering staff and consistently exhibits the firm's dedication to quality process safety management.
Did you know, the allowable total backpressure for a conventional valve can be larger than 10% of the set pressure? According to API 520-1 §22.214.171.124.3:
"In a conventional PRV application, when the allowable overpressure is 10%, the built-up backpressure should not exceed 10% of the set pressure. A higher maximum allowable built-up backpressure may be used for allowable overpressures greater than 10 % provided the built-up backpressure does not exceed the allowable overpressure."
A major United States Refinery hired Smith & Burgess to perform a site-wide revalidation.
Top 5 "Best Implemented" PSM Processes
- A PSM Check-up
Recently, as a follow-up of our webinar series, you might have taken part in the Smith & Burgess' "PSM Check-up" industry survey. This article is a reality check on what areas the survey participants thought they were doing well in compared to OSHA PSM standards as defined in OSHA 1910.119. In addition to looking into historical findings that were defined by our numerous PSM audits, we have also included some statistics from OSHA NEP Citations/Violations along with reviewing the 804 Chemical Safety Board Recommendations. This helps us to ensure that our project PSM audit's results are consistent with regulatory findings.
We see quite often that outside reviews help a facility find the regulatory gaps in their PSM processes that may otherwise go unnoticed by the client's onsite staff. It is our hope that the following items will help you see that a properly executed PSM audit can shine a light in the areas that really could use a little TLC. This independent third-party audit is a proven way to find gaps in processes.

An offshore floating production facility was originally designed with two flares: one on a boom riser and the other remotely located. Due to the design, the remotely located flare required large amounts of gas to operate. The site was interested in reducing operational costs and emissions by consolidating the two flares into the flare on the boom riser, eliminating the remotely located flare. However, there were concerns with the feasibility of such a flare consolidation, the effects of thermal radiation, and the possibility that system changes would increase the backpressures on the relief devices. Smith & Burgess was hired to review this system.
