In recent years, the control of industrial volatile organic compounds (VOCs) has become a key focus in air pollution prevention and control efforts. VOCs not only contribute to the formation of ground-level ozone and photochemical smog, but certain hazardous components also pose potential health risks to surrounding communities.

Leak Detection and Repair (LDAR) technology has become an effective and practical solution for precise VOC fugitive emission control in the chemical industry. It enables the identification and repair of leakage risks in equipment and facilities at the source, significantly reducing VOC emissions.

To further consolidate leakage control performance, T-ALL Inspection has continued to deepen its LDAR cooperation with a domestic chemical plant. Following the successful completion of LDAR campaigns in both 2024 and 2025, with results and reports highly recognized by the client and the local ecological and environmental authority, the T-ALL Inspection LDAR team re-entered the plant in May 2026 to officially launch the 2026 semi-annual inspection program.

The team strictly complied with national LDAR technical standards, focusing on key sealing points within the facility. Throughout the process, data quality was strictly controlled to ensure full coverage and efficient execution. By late May, all semi-annual inspections were successfully completed. A total of 25 excessive leakage points were identified, all of which have been repaired or are subject to targeted rectification plans.

Through three consecutive years of LDAR implementation and remediation, leakage risks within the facility have significantly decreased, and the proportion of detected leak points has declined year by year. VOCs management effectiveness has been continuously strengthened.

With consistent and standardized LDAR execution, the enterprise has not only reduced pollutant emissions and contributed to regional air quality improvement, but also eliminated operational safety risks associated with equipment leakage, reduced material losses, and strengthened stable production and green transformation—achieving a dual improvement in environmental and economic benefits.

To meet the leakage control needs of different enterprises, T-ALL Inspection provides comprehensive LDAR solutions covering the full lifecycle of process industrial facilities. From risk prevention and issue identification to corrective action implementation, we deliver end-to-end support, helping enterprises steadily move toward the goal of a “zero-leakage facility.”
