Emissions below 10 ppmV in API 622 testing.
Equipment leaks from valve glands are considered to account for approximately 50-60% of the fugitive emissions on petrochemical sites. Furthermore, the major proportion of fugitive emissions comes from only a small fraction of the sources. For example, less than 5% of valves in gas/vapour service can account for more than 90% of the fugitive emissions in a refinery.
James Walker has developed products specifically to combat fugitive VOC emissions from valves, including Supagraf Premier, Supagraf Control, and Supagraf FE. These products have proven themselves to be class-leaders in a series of third party fugitive emissions performance tests are best available technique (BAT) products for reducing industry's fugitive emissions in line with the latest Industrial Emissions Directive. James Walker fugitive emission control packings have been tested and delivered proven performance to the most exacting industry standards and end-user requirements:
