Relief System & Flare Header Analysis

Ensure Overpressure Protection

Clients contact E²G|The Equity Engineering Group, Inc. to evaluate process equipment overpressure protection, relief device sizing, and flare header hydraulics. Based on thorough review, our engineers can ensure that clients relief systems are designed in accordance with RAGAGEP and documentation meets the requirements of OSHA PSM Legislation 1910.119. Where relief system deficiencies exist E²G will use their understanding of current API and ASME codes and standards to recommend appropriate levels of mitigation to ensure proper overpressure protection.

Relief Systems & Flare Header Analysis Includes the Following:

• Development or review of existing client relief system design guidance documents that supplement the API Standards where specific guidance is not given and client’s corporate philosophy is required
• Multi-disciplined scenario review meetings to evaluate the credibility of each overpressure scenario
• Evaluation of relief devices utilizing client’s heat and material balances, process flow diagrams, piping and instrumentation diagrams, operating data, equipment and control valve datasheets, purchasing and maintenance records, and client field-verified data
• Analysis of all relief devices for acceptability and recommendations for corrective actions where deficiencies are found
• Modeling the hydraulics of the relief scenarios in the flare header to determine backpressures at the respective relief devices
• Identification of relief devices and piping segments with excessive backpressure and recommendations for corrective actions
• Structural assessment of flare header or relief piping for compliance with ASME codes
• Determination of flare radiation levels are acceptable on the ground or at nearby platforms
