Introduction

In the complex world of process safety, ensuring that facilities operate without incident requires a robust safety management system. The stakes are high in industries where a single failure can lead to catastrophic consequences, making effective process safety management essential. Relief systems and flare studies serve as critical safeguards, helping facilities prevent hazardous events and maintain safe operations. At the heart of this system are relief systems and flare studies, two essential components that help prevent catastrophic failures in petrochemical, oil and gas, chemical, pharmaceuticals, power generation, and renewable energy industries.

Interest in renewable diesel has increased significantly in recent years. In 2019, the estimated US renewable diesel consumption was 900 million gallons ^[1] followed by an estimated 960 million gallons in 2020.^[2] This trend is expected to continue in the coming years.^[3] Conversion of existing petroleum facilities to renewable diesel production provides an appealing path for many producers, but careful evaluation of the conversion must be performed to ensure that the facility is operating safely and in full compliance with PSM standards. While the existing relief and flare systems may have been adequate for the petroleum refinery service, these systems should be reviewed and redesigned along with the new process as the demand on these systems can significantly change.

After spending over 20 years in the cold Midwest winters and suffering through plant freeze ups, my mind is racing with what to look out for as things thaw back out. Please see my thoughts on instrumentation, dead legs, and a few other things to look out for based on my years of experience in the freezing weather.  

About the Author

The Opportunity:

A major United States Refinery hired Smith & Burgess to perform a site-wide revalidation.

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.

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.
