About LDAR Programme

CVR Labs runs Leak Detection and Repair (LDAR) programmes for refineries, chemical plants and process facilities to find and control fugitive VOC emissions from valves, flanges, pumps, connectors and other components. Surveys follow recognised screening practice (US EPA Method 21 approach) using calibrated instruments.

Each component is tagged, screened and logged; leaking components are flagged for repair and re-screened to confirm closure. The result is a documented emission-control record that supports CPCB / State Pollution Control Board expectations and reduces product loss.

FAQ

LDAR Programme — frequently asked questions

What is an LDAR programme?

Leak Detection and Repair systematically screens plant components for fugitive VOC leaks, flags leaking items for repair and re-screens them to confirm the leak is fixed — reducing emissions and product loss.

Which components are covered?

Valves, flanges, pumps, compressors, connectors, open-ended lines and sampling points in VOC service across your unit.

How are leaks measured?

With calibrated portable VOC analysers following the US EPA Method 21 screening approach, against agreed leak-definition thresholds.

What documentation do we get?

A tagged component register, screening results, repair-tracking log and an emission-control summary suitable for regulatory submission.
