10th ISA Fugitive Emissions LDAR Symposium
The 2010 Symposium was a great success! 228 people attended the ISA Fugitive Emission LDAR Symposium, which included representatives from EPA, state regulatory agencies and the Department of Justice. Most attendees were from companies that have to comply with EPA, state or local air quality management district LDAR rules and EPA consent decrees. There were also 24 vendors that exhibited all kinds of leak detection, inspection, repair, component tracking databases and materials to prevent or reduce emissions, reports Barrie Kirkman....
Assessing fugitive emissions performance in valves and packing
This paper describes a test procedure for valve emissions developed by ChevronTexaco together with Yarmouth Research. Also presented are the results of various tests on valves typically found in refineries. The authors conclude that it is possible to significantly reduce fugitive emissions to the point where almost all valves should remain in compliance....
DBB vs. DIB
Double block and bleed functionality has long been available, but the term is often incorrectly applied. Jeff Partridge explains all, and also suggests that sometimes double isolation and bleed might be a better alternative....
Emission measurements of industrial valves acc to TA Luft and EN ISO 15848-1
As the title suggests, in this article Professor Dr.-Ing Alexander Riedl looks into the implications of measuring emissions according to TA Luft and EN ISO 15848-1 and points out some important conclusions....
Experiences with API standard 622 type testing of process valve packings
The publication of the API 622 specification has marked a departure from the common method of evaluating packing performance as a part of valve qualification tests. Instead, API 622 evaluates packing performance in a standardized fixture, outside the influence of a particular valve’s design. This article will outline the use of API 622 in tests performed by Yarmouth Research and Technology. The general experiences performing API 622 emissions tests were positive ones. This paper describes the test procedures, our results in performing the tests on a braided flexible graphite packing, and the lessons that were learned....
Fugitive emission testing (in practice)
In this article, Colin Zegers describes the testing of valves with regards to fugitive emissions in practical situations. Examples, experiences and possible solutions are presented and explained in detail as well as some general terms are pointed out for better understanding....
Fugitive emissions: guidelines for successful valve upgrades
Due to the upcoming emission legislation in Europe, most chemical and process industry plants will have to adhere to strict legislation when replacing sealing elements during shut-downs, argue By Ralf Vogel, (Engineering Manager, Burgmann Packings Limited); Stefan Danner (Applications Engineer, PSS Division, Burgmann Industries GmbH & Co. KG.) and Bob Smith (Product Marketing Manager, PSS Division, Burgmann Industries GmbH & Co. KG) ...
How to manage fugitive emissions?
Fugitive emission management is an important area of attention throughout the international politics and (petro-) chemical, refinery and oil & gas industry. This article by Hans Hooyberghs (The Sniffers NV) focuses on the possibilities of managing and reducing these emissions....
Maintaining integrity - a managed approach
Leakages from valve stems have been well documented and many companies are taking steps to reduce emission levels. However, have you stopped to consider the flanges on your valves and other piping components? Tony Nicholls (Furmanite International) examines the factors causing leaking joints and the actions required to ensure joint integrity....
Management considerations in choosing valves to curb fugitive emissions
In this article, Michael Adkins (Swagelok) presents possible solutions for fugitive emission control management for valve users. After a general introduction, the focus is shifted to LDAR programs, which are broadly used in US facilities and some supporting examples are given....
Minimising fugitive emissions: LNG best practice
Ask any LNG plant manager their number one priority, and the answer will be the same: safety. It is closely followed by – and linked to – further important priorities such as productivity and supply chain management. It is widely accepted that control valves play a critical role in each of these areas. After all, optimum valve performance is vital in the prevention of fugitive emissions, as well as maximising plant performance. By Tim Webb, Severn Glocon....
