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.

Our Solution:

Smith & Burgess’ engineers were able to recommend installing a SIL 2 System to eliminate the heat source and thereby mitigating the higher flare load.

The Results:

The customer was able to reduce the higher flare load with our recommended solution which resulted in a cost saving of $250,000 and no in-field modifications.

  • Facility Type: Refinery

  • Services Provided: LOPA Review & SIL/SIS Design

  • Money Saved: Over $250,000 Dollars

 Safety Knowledge Should be Shared...

“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.
