What does ldar detection mean?

ldar detection means the abbreviation of leak detection and repair. LDAR detection is a kind of use of specialized gas detection instruments to detect the concentration of volatile organic compounds such as equipment and pipeline components, and to regularly check whether there are leaks. And work practices to replace or repair leaking components within a specified time to reduce emissions of volatile organic compounds.

##ldar detection means

LDAR detection is leak detection and repair（Leak LDAR detection is the abbreviation of Detection and Repair), which uses specialized gas detection instruments to detect the concentration of volatile organic compounds such as equipment and pipeline components, regularly checks whether there are leaks, and replaces or replaces leaking components within a specified time. Remediation of work practices to reduce volatile organic emissions. (Fume online monitoring equipment)

The control objects for leakage of equipment and pipeline components refer to various materials (gas/steam, light liquid, heavy liquid) containing volatile organic compounds (Volatile Organic Compounds, VOCs) inside. ) devices and equipment, including valves, flanges, pumps, compressors, compressor sealing system vent pipes, pressure relief devices, open valves or open pipelines, agitator seals, channel door seals, and exhaust pressure relief of sealed systems pipes, accumulator pressure relief pipes, storage tank ventilation pipes and other pipe connections.

It is recommended that petroleum refining and petrochemistry, chemical industry, pharmaceutical manufacturing, surface coating, printing and packaging, etc. develop leak detection and repair technology.

Technical significance of implementing

LDAR detection: VOCs can participate in atmospheric photochemical reactions, dominate the main chemical process of ozone pollution in urban areas, and are also one of the important precursors of secondary organic aerosols one.

Therefore, in urban and regional air quality management and pollution control, the research and pollution prevention of atmospheric VOCs are very necessary. In addition to traditional organized emissions, the volatile nature of VOCs must be taken into consideration, and attention should be paid to the control of unorganized emissions. In some industries such as petrochemicals, more than 70% of VOCs emissions come from unorganized emissions, equipment and pipes. Valve leakage is the second largest source of fugitive emissions of volatile organic compounds after storage and transportation.

According to statistics from the U.S. Environmental Protection Agency, the implementation of LDAR measures in petrochemical plants can reduce fugitive emissions by approximately 63%, and general chemical plants can reduce fugitive emissions by approximately 56%, bringing huge environmental benefits.
