COVID-19: Operating Facilities Safely During A Pandemic

Posted by Jeremiah McAfoose on Apr 20, 2020 1:15:33 PM

The COVID-19 Challenge

As the COVID-19 disease became a pandemic in the span of mere weeks in USA (months for the world), most of us who work in the process safety/engineering field has probably asked, or been asked:

  • What kind of precautions have you taken to minimize the COVID-19 spread through:
    • Human contact
    • Computer equipment
    • Shared office spaces
    • Common areas
  • How do you determine “non-essential” personnel that should not have access to your facility?
  • What is your contingency plan if/when travel or access is restricted?
  • How can you keep normal work efficiency for these “non-essential” personnel working offsite?
  • What kind of resources do you need to work offsite?

Did You Know: PSV Isolation on Air Receivers

Posted by Brandon Ring on Jan 14, 2020 11:26:07 AM

 

Did you know, OSHA does not allow block valves on the inlet of relief valves installed on air receivers in compressed air systems?

OSHA CFR 1910.169(b)(3)(ii) states, “No valve of any type shall be placed between the air receiver and its safety valve or valves.”

Did You Know: Set Pressure of PSVs Protecting Process Pipes

Posted by Brandon Ring on Jan 14, 2020 11:15:36 AM

 

Did you know, relief devices that protect process pipe may be set to open above the piping design pressure?

Per ASME B31.3-2016, Sections 322.6.3. (see Figure 1) and 302.2.4 (f) (see Figure 2), a thermal relief valve may be set up to 120% of the design pressure of the protected system with the owner’s approval, as long as, the allowable accumulation criteria in 302.2.4.(f) are met. Set pressures lower than 120% of the design pressure may be required depending on the allowable accumulation pressures in 302.2.4 (f).

New Decade’s Resolutions?

Posted by Brandon Ring on Jan 13, 2020 5:21:56 PM

"Great teamwork is the only way we create the breakthroughs that define our careers."

As we enter 2020, most of us have already taken a moment to reflect on last year's successes and failures. (At least on a personal level.) A somewhat painful and unavoidable exercise to help guide your decisions in the upcoming year.

However, how many have taken stock of our past decade's personal successes and failures? If you haven't, quickly give it a shot right now.

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.

Case Study: Third Party Relief Valve Mitigation Review

Posted by Dustin Smith, P.E. on Nov 1, 2017 6:03:00 PM

The Opportunity:

A major US refinery used a competing engineering contractor to perform a flare and relief systems analysis. Upon completion of the project, the refinery was left with a list of facility upgrades that management deemed excessive. Smith & Burgess was hired to review the relief and flare systems documentation and provide engineering solutions that met corporate and industry requirements.

Case Study: Gas Plant Detailed Relief System Design Review

Posted by Dustin Smith, P.E. on Sep 1, 2017 6:04:00 PM

The Opportunity:

A recent audit of a “rebuild” design package for a major Asian gas plant identified that the EPC may have failed to follow company or industry standards. The owner needed an engineering review of the entire facilities’ relief systems designs prior to their start up in two months. Any deficiencies in company or industry standards needed to be addressed prior to the facilities’ start up.

 Safety Knowledge Should be Share...

“It should not be necessary for each generation to rediscover the principles of process safety which the generation before discovered. We must learn from the experience of others rather than learn the hard way. We must pass on to the next generation a record of what we have learned.” - Jesse C. Ducommun, Safety Pioneer
 
As Process Safety engineers and consultants, we believe our unique position creates a responsibility for Smith & Burgess to share our years of accumulated safety knowledge.
