Top Ten Things Affecting the Quality of your Relief Validation Study

Posted by Brandon Ring on Feb 24, 2019 1:31:43 PM

Pressure relief systems and devices are used to prevent equipment and pipework from over-pressurization which can lead to mechanical failure and associated release of containment.

In order to function correctly, relief systems need to be properly designed to recognized standards, correctly installed and properly maintained. Changes to associated plant and pipework also need to be appropriately managed; often, seemingly unrelated changes can have an impact on the relief case of the system and render it incapable of protecting the system as designed. This is seen particularly on older plants with poor change management history.

The following list provides some details on the areas you should focus on when improving the quality of your Relief Validation Study.

Top 5 "RAGAGEP Deviations" in New Construction

Posted by Dustin Smith, P.E. on Aug 28, 2018 10:51:00 AM
 

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.

Did You Know: Allowable Backpressure for a Conventional Valve...

Posted by Brandon Ring on Aug 1, 2018 5:51:00 PM

 

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 §5.3.3.1.3:

"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."

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.

Case Study: Elimination of a Remote Flare System

Posted by Dustin Smith, P.E. on Mar 4, 2018 6:09:00 PM

The Opportunity:

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.

Case Study: Wellhead Gathering System Overpressure QRA

Posted by Dustin Smith, P.E. on Jan 1, 2018 5:58:00 PM

The Opportunity:

A review of the “overpressure protection plan” for a wellhead gathering pipeline found that the potential for “multiple simultaneous well shutdown system failures” had been overlooked. The flowing pressure on the inlet to the well choke valve exceeded the allowable pressure in the gathering system. If multiple well safety systems failed, there would be an unacceptable potential for large-scale loss of containment. A Quantitative Risk Assessment of the entire system was needed to determine if the existing overpressure protection system, as a whole, met corporate and regulatory requirements. Initially, the protection plan suggested additional shutdown hardware and increased testing frequency. Smith & Burgess was hired to review this system.

Spring Loaded Relief Valve Details: Valve Internals

Posted by Dustin Smith, P.E. on Dec 22, 2017 11:33:00 AM

 

Spring Loaded Relief Valve Details: Valve Internals 

A spring loaded relief valve is used in many applications to protect the over pressurization of vessels, pipes and containers. Conventional and balanced bellows relief valves are examples of spring loaded relief valves. Codes and standards like ASME, API,and ISO (to name a few) require that these relief valves are sized to have a relieving capacity that is sufficient to maintain the integrity of the system by preventing the internal pressure for exceeding the design limits. In general, the relief valve is designed and selected by the relief systems designer to meet process-engineering requirements.

Case Study: SIL Design

Posted by Dustin Smith, P.E. on Dec 2, 2017 6:05:00 PM

The Opportunity:

As part of a relief valve study, a competing engineering firm recommended a major United States refinery to replace multiple relief valves and modify the associated piping on a column system in order to mitigate for a higher flare load. The proposed changes would have cost the refinery approximately $300,000. Unsure of the recommendations and associated expenses, the refinery reached out to Smith & Burgess to review the EPC’s findings.

Part 1: 3 Steps to Integrate "Flare System Management" into Your Project Life-cycle and Maximize the Benefits

Posted by Dustin Smith, P.E. on Jun 28, 2017 12:23:00 PM

The Evolution of American Refining:

Refineries and petrochemical facilities today are faced with a choice: either increase efficiencies and throughputs or be put out to pasture. While the capacity of the average refinery has almost doubled in the past 30 years, per Energy Information Administration (EIA) data, the capacity of the average flare system generally has not. This is not a mere academic issue. In the US, the number of operating refineries dwindled from ~200 in 1985 to only 137 thirty years later (per the EIA); over the same thirty years, the total US throughput has increased by 25% (or significantly more depending on how you quantify the increase in complexity).

This growth in capacities and efficiencies is instrumental in succeeding amongst the rigors of a "keep up or be left behind" economy. Driven by major projects, these process changes include adding new equipment, changing existing processes, and creating more integrated heating and cooling.

However, during all the major project pushes, one thing is often lost, overlooked, or left for the last minute: integrating changes into the existing flare system and doing so in a manner that provides the maximum benefit to the organization.

Top 7 Mistakes Lurking in your Relief Valve Calculation Database (and How to Avoid Them)

Posted by Dustin Smith, P.E. on Jun 23, 2017 1:26:00 PM

 

 

#7) Relief Valve Database is Outdated Due to Changes in Process

So, you receive your relief valve data base from your Process Safety Consultant and just like a computer bought anytime in history, it is out of date before you open the box. Changes happen at a pretty high pace in most facilities. Dealing with Management of Change must include the effect of the change on the Relief System Database and documentation. Not keeping this documentation up to date makes your relief system documentation almost as valuable as that "new" computer.

TIP: Dedicate resources to keep this relief valve database up to date. These resources could be a team of process engineers, a dedicated relief system expert, or a Process Safety Consultant. Process Safety Consultants can provide this service on a T&M basis, so you only pay for what you use and they bring their experienced knowledge base to perform this function efficiently.
