The Separex system, a spiral-wound cellulose acetate configuration, from the Hoechst Celanese subsidiary, will process approximately 11 million scf/day of purge gas from a new hydrodesulphurisation unit. The skid-mounted facility, which is expected to go into production in 1993, will recover high purity hffdrogen for recycle within the refinery complex, reducing operating costs by energy saving. Separex has also recently completed the installation of a natural gas purification unit for a major petroleum company in central California. This will process 1.25 million scf/day of natural gas from an offshore platform, reducing CO z content from 10% to 3% to meet commercial pipeline specifications.
New society The Korean Membrane Society was formed on 2 November 1990, after many years of informal meetings, it is reported in Membrane Quarterly. Founding president is named as Dr Un Young Kim, of the Korean Advanced Institute of Science & Technology, and vice president is Professor Chang Kyun Choi, of Seoul National University. Initial membership is approaching 200.
Du Pont settles on hollow fibres In its commitment to strengthen its position in hollow fibre forms, particularly for seawater desalination, Du Pont has announced it will discontinue its Permasep spiral wound RO membrane product range. These were acquired with the purchase of Ajax in 1982. The company believes that seawater desalination has the best potential in the RO market, and that its hollow fibre membranes are better suited to this application.
Gelman sells peripherals Gelman Sciences Inc, Ann Arbor, Michigan, USA, has announced that it will sell off two of its non-core activities, in order to "focus on microfiltration and strengthen its balance sheet." The assets of its
Membrane Technology
Australian subsidiary which consist primarily of machinery and equipment for manufacture of nonwoven products will be sold for $175,000, while full support will still be given to its Australian microfiltration business. The divestiture in Australia began in 1989 when earnings began to decline; the remaining operation will still act as distributor for non-wovens. The second divestment is the sale of both technology (its US Patent) and manufacturing equipment for blood filters to Cobe Cardiovascular Inc, Arvada, Colorado, USA, for $275,000 plus five years royalties, estimated to be worth $150-300,000.
High purity cartridge filter A polycarbonate membrane filter designed for purifying electronic rinse waters and deionised water applications has been developed by Osmonics, Minnetonka, Minnesota, USA. The novel radiation track etched membrane has a very sharp micron cutoff, the company says. The cartridge assembly is made from all pure polypropylene and polycarbonate, so that it offers the necessary high purity. Cartridges are available for 0.05, 0.1 and 0.2 microns and fast rinses up to 18 megohm-cm are claimed.
Calling notice A first announcement and call for papers has been issued for the conference Engineering of Membrane Processes, sponsored by the European Society of Membrane Science & Technology and organised by Elsevier Seminars, Oxford, planned for 13-15 May, 1992, at Garmisch-Partenkirchen, Bavaria, Germany. The location is a world famous alpine resort, and the meeting is said by the organisers to be of value to both industrial and academic participants who are or will be - involved with the application of membranes in processing. The two-fold aims are to examine existing concepts and knowledge across the wide range of membrane processes, and to explore future processing methods and opportunities. It is anticipated that the programme for this major event will attract participation from all continents. Prospective authors are invited to submit abstracts not exceeding 300 words.
