Petrochemical Manufacturing Facility LDAR Program Development
Trihydro assisted a large petrochemical manufacturing facility with its regulatory compliance efforts by developing a system to track organic hazardous air pollutant determinations for more than 1,500 transmission lines and 900 pieces of equipment.
As part of these efforts, our team provided compliance determinations and recommendations regarding Miscellaneous Organic National Emission Standards for Hazardous Air Pollutants Leak Detection and Repair (LDAR) requirements.
The project included developing an equipment and piping list to track organic hazardous air pollutant determinations for more than 1,500 transmission lines. Trihydro also identified and characterized a miscellaneous organic chemical processing unit 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 the following elements:
- Equipment
- Individual pipe runs
- Stream compositions
- Corresponding process-flow diagrams and piping and instrumentation diagrams
The database is configured to operate through an online interface, allowing the client to access a secure 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. This effort greatly reduced the potential for errors in reporting while supporting expandability.
Following project completion, Trihydro reviewed databases previously audited by the U.S. Environmental Protection Agency to confirm its findings and assisted the client with field verification, phenol unit LDAR inventory and tagging, and database conversion.
