Fugitive emission control

Paul Boughton

James Walker has announced a stable of products which meet the stringent requirements of TA-Luft air quality control regulations, ensuring the highest levels of emission control.

These include Metakamm Kammprofile grooved metal gaskets, Metaflex spiral wound gaskets, Metcom semi-metallic gaskets plus Supagraf Premier and Supagraf Controlgraphite-based packings for valve stems.

Metakamm Kammprofile gaskets offer optimum sealing performance for flanges on high temperature/pressure pipework and vessels where operating conditions can fluctuate. Metaflex spiral wound gaskets are now available in material combinations to suit all applications for high-integrity sealing at pressures from high vacuum to 350+ bar over temperatures from cryogenic to 1000degC.

Supagraf Premier and Supagraf Control are top-of-the-range graphite packings specifically developed to control fugitive emissions from on/off and control valve stems respectively. They contain advanced lubricant systems that prevent the pick-up of graphite on stems.

The TA-Luft (Technische Anleitung zur Reinhaltung der Luft) sets maximum permissible limits for emissions when processing, conveying or transferring dusty, liquid or gaseous materials, taking into account the specific risk potential.
