Flushing method leak detector developed
General news and quantitively analysed by a flame ionisation detector. The mass of the leakage per time unit is calculated from the gas flow rate and the concentration of a sample of the leakage in the purging gas after mixing. Advantages of the method are the quantitive sampling and the facility for continuous measuring. The measurable ran e is between 0.001-40 g/h or 0-100,000 mg/m 3gand is accurate to +I- 5%.

Flushing method leak detector developed In 1990 the Verband Deutsher Maschinen und Anlagenbau (VDMA) in Germany initiated a project focussed on improving existing fugitive emission measurement technology. The technique which resulted is a combination of EPA Method 2 l’s sniffing technique and the bagging method. The flush gas measuring technique has been developed by Pacific Wietz in Dortmund, Germany, and is now ready for commercialisation. The Dectolyt 1000, manufactured by Junkalor, is the first device to use this method, and can produce results in ppm as required by EPA Method 21 and in g/h, as required by VDE 2440. The unit is portable, connects using quick action couplers and downloads to a PC. The measuring principle involves vaporisation of the leaking compound within a defined purging gas flow. The flow of flush gas is enriched by emissions

The International Rubber Digest reports a marked and consistent improvement in performance for the elastomer industry. The market hit a low point around January 1994 but has grown fairly steadily since, with no downturn predicted. Natural rubber prices have risen since August and are a good indication of the picture as a whole. Last summer the possibility of a significant long-term agreement between Thailand and China, fuelled by the acquisition of Thai RSS3 by China, stimulated increasing demand for natural rubber. Inclement weather conditions in Malaysia may also have influenced rubber prices, as fears of shortages in supply grew. Currency transactions were discounted as having had any impact on the market towards the end of the year.

John Crane to accelerate growth in China John Crane International is set to accelerate its growth in the rapidly expanding mechanical seals market in China, following the acquisition of a controlling interest in its existing Chinese seals joint venture. Control of the venture, which has been renamed John Crane Ltd. (Tianjin), will facilitate the transfer of the company’s shaft sealing technologies and manufacturing expertise to China, the world’s fifth largest market for mechanical seals by volume. As a consequence of China’s fast developing economy, there is growing demand for higher integrity mechanical seals which increase process efficiencies
