Technical Toolkit

Cognascents is dedicated to providing our clients with experts that are up-to-date with the latest working knowledge across the Process Safety and Process Engineering spectrums. In striving to achieve this goal, our experts are often a part of technical discussions and debates. The Technical Toolkit will serve as our avenue to share information learned from these experiences within the dynamic Process Engineering and Process Safety Worlds.

Be sure to keep coming back to this web page as the toolkit begins to fill up. Additionally, click here to subscribe to our newsletter where you can read the latest Technical Toolkit posts as soon as they come out!

What Computer Algorithms Tell Us About Prioritizing Relief System Deficiencies

When the dust settles after completion of a facility’s relief system design revalidation, the difficult task of mitigating any identified deficiencies begins. The question inevitably arises as to which deficiencies to address first, and if your facility has recently undergone a unit wide or facility wide relief system revalidation, you may be wondering how to…

What’s In Your Pipes?

Some time ago, a client had a heat and material balance that they wanted recreated and scaled, but the only documentation the client had in regards to process chemistry was a set of PFDs with stream tables. Based on the flow rates and compositions on the page (what was appearing and disappearing), I had to…

Texas….Pipes, Pipes, Freeze Baby

Alright; stop, grab a seat, and listen… It was COLD in Texas.  REALLY cold. However, with simple planning for reliability, Texans could have possibly prevented multiple pipe-freezing failures that are continuing to plague many as we thaw out from Winter Storm Uri.  Hopefully, my story and observations of our collective pipe-freezing situation will remind us…

Keyed-Valve Interlocks

  Several years ago, while working in a refinery, I noticed a relief valve with its inlet block valve completely closed. I radioed an operator for assistance. Within minutes, two operators arrived and confirmed that the valve should not be closed. They opened the valve and thanked me for notifying them. In following up a…

Considerations when Establishing a Mechanical Integrity Program for a Process Safety Management Regulated Facility

Energy organizations such as chemical manufacturers, oil and gas production, and even pharmaceutical manufacturers strive to maintain a Process Safety Management (PSM) program to ensure the safety of their employees and those around their facilities. Many of these organizations are familiar with the requirements of PSM including the process of conducting Process Hazard Analysis (PHA)…

PHAs and Flare Systems

At every facility, there is a point during the process hazard analysis when the team inevitably dives into “the black hole” of flare/relief/scrubber systems.  Following strict HAZOP analysis methodology, a team documents all deviations from normal operating limits.  However, with most relief systems, this leaves the team facing numerous causes, and with each source, having…

Group & Self Accountability in Process Hazard Analyses

When performing a process hazard analysis (PHA), often people of different positions and specializations are gathered in the meeting room to assess the chosen process on its safety and ability to safeguard against inherent hazards. These groups can include personnel from maintenance, operations, engineering, HS&E (Health, Safety, and Environmental), and management. This diversity of thought…

No…You Will Never Use That in the Real World, but That’s Not the Point!

The point of education is not just to learn facts or be able solve math problems, but to develop skills that make us better, more well-rounded individuals. So, with that said, the next time that a recent college or high school graduate complains about having had to learn, “things they will never use again,” remind them that the critical thinking and reasoning skills that they developed are more important than the actual information they had to study.
