By working together Wealone.,canachieve greater benefits than one company Fugitive emissions cost industry £ million in product loss, repair costs and reduced plant reliability and efficiency. BP Chemicals has already devised a plan w~c~ will almost halve fugitive emissions from valves on its own plants and looks set to save more than £1 million per year in production costs. potential savings result from an innovative parmership between BP Chemicals and 10 suppliers of industrial packing which seals the joint at the valve stern (see Sealing Technolosy number 2). BP Chemicals is now using improved packings on all new valves at its sites and will fit new packings to existing 'leaky valves' over a four year period.


FMJ International Publications Ltd has just published the 1994 edition of the European Adhesives & Sealants Yearbook. Comprising 74 A4 pages, this pan-European directory is a guide for both manufacturers and users of adhesives and sealants. Its main directory section is divided up into separate headings. These include trade and research associations, adhesive and sealant manufacturers, trade names, adhesive and sealant suppliers listed by type, adhesive and sealatat suppliers listed by end use, as well as raw material and equipment suppliers.

Association technical


s~m*,os;um~vThe 5th Annual Technical Symposium of the Fluid Sealing Association has been arranged for 2-4 October 1994. It is to be held at Fort Lauderdale, Florida. The symposium has been organised to provide a forum to address the products, technologies, evaluation methods and codes and standards. This will enable engineers and designers to meet the requirements placed on the fluid sealing components within their opreating facilities.




The keynote address is to be given by ALan Selz, the chairman of the ASME Special Working Group; he will be discussing the forthcoming ASME design codes for the design and use of gasketed joints, with emissions being the criteria~ Other speakers include Michel Dererme of the Tightness Test and Research Centre, Ecole Polytechnique, University of Montreal, "Recent developments in PVRC Elevated Temperature/Gasket testing"; Cyril Latty of Latty International, "EG Project Brite - European Standardisation"; Arnold Frances of E.I. DuPont, "A Steam Service Gasket Qualification Test Fixture and Procedure"; Garry Dodson of SEPCO, "Valve Fugitive Emissions - the Next Step" and Ed Euwer (moderator) of PacSeal Inc, International, "Mechanical Seals". The Symposium will also feature table top displays from international manufacturers of fluid sealing components. Attendance of the Symposium will be limited to 300 delegates, Contact: Fluid Sealing Association, 2017 W a l n u t Street, P h i l a d e l p h i a , PA 19103, USA.

Emissions s p o t l i g h t e d at STLE al

se s e course



a t i o n

The 49th Annual meeting of the Society of Tribologists and Lubrication Engineers (STLE) was held in Pittsburgh at the beginning of May. The meeting comprised a number of technical sessions and education courses. A two-day seals education course was sponsored by the STLE and the Institution of Mechanical Engineers (I Mech E). The forum focussing on Emissions was opened by Ralph Gabriel, (John Crane Inc) chairman of the seals education course and Frank Bnssick, (EG & G Sealol) the chairman of the seals technical committee. A number of presentations were made concentrating on controlling emissions on different types of machinery and ways to meet ever changing legislation and regulations. Among the speakers were Bruce Jordan from the US Environmental Protection Agency (USEPA). Mr Jordan spoke on the Clean Air Amendments, bringing the audience up to date with what has happened since November 1993 and what the planned strategy was for the future. He focussed on three key areas; the progress and implementation of the Clean Air Amendments, the difficulties associated with the Amendments and the appropriate solutions. One of the problems he highlighted was the duplication of data; industry, the State and associations should all work together planning the most useful action for a specific case.

Tom Kittleman, E.I. DuPont discussed the recent pump seal mass emissions study carried out by the Chemical Manufacturers Association in the US (CMA) and the STLE in some detail (see Sealing Technology

number 4). Ken Shepherd, Polysar Rubber Corporation discussed, as an end user, ways to control emissions on mechanical sealed equipment in the petrochemical industry. The paper provided an overview of rotary shaft sealing applications on hazardous and dlffficult-to-seal process fluids in the petrochemical industry. Mr Shepherd presented a number of actual case studies for sealing systems on c e n t r i ~ a l and rotary pumps and agitators. In his paper he included design features to be taken into consideration to increase mean time between planned maintenance (MTBPM) for specific sealing systems. The paper also highlighted the success obtained with double coaxial agitator seals; a technology that is said to be more common in Europe than the US. Three STLE special publications were presented in the education course. Bill Adams, Durametallic Corporation presented the the STLE SP-30. guidelines f o r

meeting emission regulations f o r rotaffng machinery with mechanical seal£ The STLE SP-32 - controlling emissions with face and circumferential seals on rotating equtpmentwas presented in two sessions by Robert Schmal, Stein Seal Company and Glenn Pecht, John Crane. The STLE SP-33 - controlling emissions on valves was presented by Michael, Worcester Control Corporation. The education course was rounded off by an I Mech E Panel Session. The panel members were Nell WaUace, Flexibox Ltd, Bernard Nau, BHR Group and John Plumridge, EG&G SealoL Among the subjects covered by the panel members were the history of the I Mech g and the Institution's Seal Reliability Initiative. The technical sessions which followed the seals education course concentrated on two main areas, emissions control technology and design. Details of the papers presented at any of the sessions can be obtained from the STLE. Contact: The Society o f T r i b o ~ a n d Lubrlca. t l o n Engineers, 840 B u u e ~ , Pa~ ~ , EL 60068, USA.
