TP Europe’s video “ Leak Detection and Repair (LDAR)” outlines the company’s methodology for developing systems to detect, analyze, and generate repair orders concerning chemical leaks in industrial settings. Their process targets selected global Industries, including tank storage, refineries, (petro) chemical plants, gas plants and terminals, and offshore platforms.
The first step in the process (called TP.AIM) involves preparation and database setup.
Executing this step appears to require detailed flow charts describing the facility’s process flows and the chemicals used or created at each step in the process.
Once programmed, the system is deployed in the facility’s control room as part of its safety procedures.
The third step is to calibrate the process by measuring or performing tests to determine the presence of specific chemicals in the area under normal operating conditions.
After the calibration, the facility employs the EPA Method 21 measurement process (and local alternatives) that uses a handheld tool to measure the target chemical levels at various locations in or around the facility.
Following the EPA Method 21 measurement, the system analyzes the data, identifies problems, and creates repair orders to resolve any issues detected.
The benefits of the leak detection and repair process include reduced fugitive emissions, the continuity of production processes, and cost savings.
