LDAR Program Development

Petrochemical Manufacturing Facility

Services Provided


This project was completed at a large petrochemical manufacturing facility in the Midwest. The client requested that Trihydro provide compliance determinations and recommendations regarding the Miscellaneous Organic National Emission Standards for Hazardous Air Pollutants (MON) Leak Detection and Repair (LDAR) requirements for their facility. The project included the development of an equipment and piping list to track organic hazardous air pollutant (OHAP) determinations for more than 1,500 transmission lines. Trihydro also identified and characterized a miscellaneous organic chemical processing unit (MCPU) and the associated 900 affected pieces of equipment.

To manage the volume and detail of supplied data, Trihydro used a relational database to form a comprehensive program based on 1) equipment, 2) individual pipe runs, 3) stream compositions, and 4) corresponding process-flow diagrams and piping and instrumentation diagrams (P&IDs). This effort greatly reduced the potential for errors in reporting while adding the prospect of expandability.

The database is configured to operate through an online interface, allowing the client to access a secured website for data and applicability determinations for each piece of equipment and transmission line. To support the determinations, the project team imported stream-composition data and provided physical locations for each piece of equipment and transmission line.

Upon completion of this project, the client asked Trihydro to complete a parallel database review of information previously reviewed by the Environmental Protection Agency (EPA) during an audit. The purpose of the review was to verify EPA findings. Trihydro also assisted the client with a field verification project, phenol unit LDAR inventory and tagging effort, and a database conversion.
