From Mountz, Inc.
The Clean Air Act requires refineries to develop and implement a Leak Detection and Repair (LDAR) program to control fugitive emissions. Fugitive emissions occur from valves, pumps, compressors, pressure relief valves, flanges, connectors and other piping components. A study conducted by the Pressure Vessel Research Council (PVRC) in the
USA indicated that a significant percentage of flange joint failures resulting in leaks were due to loose bolts.
Improper torque of high-pressure vessels can be attributed to safety incidents that cause financial loss, loss of property and even loss of life. The more volatile and dangerous the substance the more critical it is to take precautions to ensure flanges and bolts have been properly torqued and most importantly, properly audited.

Topics of Interest
More and more attention worldwide is being focused on fugitive emissions. Fugitive emissions are defined variously and may refer to a wide range of emissions not confined to a stack, duct, or vent,...
9.9 Fugitive Emissions
9.9.1 Introduction to Fugitive Emissions
In many industrial regions of the world, increasing levels of environmental pollution have led to enactment of strict...
Since refineries and chemical plants handle large quantities of volatile organic compounds (VOCs), some emissions of these compounds are likely during normal operations. Based on studies in the United...
Bonnets
A valve bonnet covers the opening through which the internal parts are inserted. The bonnet serves as the mounting base for the actuator. It includes the seal which prevents fluid leakage...
Leaking Pipe Flanges and Hot Bolting
This chapter is oriented to in-plant piping maintenance and repairs. The methodology can be applied to pipelines, especially the sections on sleeve design.
