Any worry about leakages?

Fugitive emissions are emissions of gases or vapors from pressurized equipment due to leaks. As well as the economic cost of lost commodities, fugitive emissions contribute to air pollution and climate change. Fugitive emissions by petrochemical industries present high risks and hazards. Leaks from pressurized process equipment generally occur through valves, pipe connections, mechanical seals, or related equipment. Fugitive Emissions / leaks?

The Clean Air Act in USA The Clean Air Act is a United States federal law designed to control air pollution on a national level. (major amendment signed in 1990) “The Act requires industrial facilities to implement a Leak Detection and Repair (LDAR) program to monitor and audit a facility's fugitive emissions of volatile organic compounds (VOC). The program is intended to identify and repair components such as valves, pumps, compressors, flanges, connectors and other components that may be leaking. These components are the main source of the fugitive VOC emissions.”

Innovation for safety Fugitive Emission Monitoring

Fugitive Emission Monitoring increases highly the safety of the plant (people & environment) Immediate Alarm for a quick intervention Reduced exposure of personnel to a potentially deadly chemical Easy implementation on existing valves, without additional cabling

Fugitive Emission Monitoring Bellows seal Bellows seal bonnet is used for dangerous medium, potentially fatal for people and environment  Chemical industries  Pharmaceutical  …

Fugitive Emission Monitoring Bellows seal Number of cycle/stroke Packing PTFE Tightness First Emission from Packing Bellows Tightness Metallic bellows seal are used to keep a constant maximum tightness but… one crack of the bellows is fatal  Need of accurate follow-up Secondary gland packing seal Bonnet Metallic bellows Rising spindle Constant tightness

Fugitive Emission Monitoring Bellows seal Number of cycle/stroke Bellows Tightness Cracks happen in the bellows with no warning sign and the consequences can be extremely damaging. Statistically every manufacturer knows more or less the life time of bellows. However pressure and temperature of the medium can impact this life time. Metallic bellows seal are used to keep a constant maximum tightness But one crack is fatal  Need of accurate follow-up Secondary gland packing seal Bonnet Metallic bellows Rising spindle

Secondary gland packing seal Fugitive Emission Monitoring Pressure in the bonnet The only effective monitoring is to put under control the pressure inside the bonnet. Under process pressure No pressure / pressure only in case of leak
