Filmtec wins injunction against Allied Signal . . .

The Separation Products Division of Hoechst Celanese Corp., has purchased the Separex Membrane Systems operation from Air Products & Chemicals. As a result, Separex becomes a business segment within SPD Hoechst Celanese, and the sales and engineering operations will relocate from Allentown, PA, to Charlotte and Houston in the near future. . . . In September 1994, Hoescht decided to sell the Separex gas separation business to UOP (IL, USA) along with a Hoescht Celanese manufacturing plant in

In February the US District Court granted Filmtec, a subsidiary of Dow, a preliminary injunction against the Fluid Systems Division of Allied Signal. The injunction prohibits Allied Signal from making or selling TFCL membranes while a law suit for infringement of US patent 4277344 is pending. It is understood that the injunction became effective on I March. . ..This dispute centred on a Filmtec patent invented by John E. Cadotte regarding the preparation of a reverse osmosis membrane, which was filed in 1981. Although

developed by the US Department of Energy’s Argonne National Laboratory can reduce the cost of an environmentally benign solvent, ethyl lactate, enabling this solvent to compete in the marketplace against toxic solvents. Ethyl lactate is biodegradable and non-toxic the US Food and Drug Administration long ago approved its use in food products. It is thought that ethyl lactate is a good candidate to replace other toxic solvents such as chloro-fluorocarbons, which damage the earths ozone layer, and volatile organic compounds, some of the USA’s most common ground-water pollutants. It is reported that each year, the United States uses more than 3.8

According to industry estimates, solvents made with ethyl lactate can replace conventional solvents in more than 80% of these applications. Argonne reduced the cost of producing ethyl lactate by improving separation and purification techniques in fermentation-based process to manufacture it, said Jim Frank, the scientist who manages the project for Argonne. “But our major breakthrough,” Frank said, “is a new, patented advanced membrane

income Ionics has reported that for its six month period ended June 30, 1998, its net income fell 25.4% to US$ 15.57 million on revenues of US$ 159.2 million. Revenues for this period fell 8.6% from a figure of US$ 174.2 million for the same period in 1997. Ionics also reported losses for its second quarter results with revenues of US$ 80.3 million, down 7.9% compared with the same period in 199’7. Net income for this quarter showed a further decline of 36.4% at US$ 4.6 million compared with US$ 7.23 million in the second quarter of 1997. Ionics said that backlog at the end of the quarter was US$196.8 million compared with USS 153.6 million at the beginning of 1998 an increase of 28%. Ionics boss, Arthur L. Goldstein, explained that, “lower revenues from customers for water equipment and systems, especially those in the microelectronics industry, and the consolidation of the Company’s SeparaTech business”, were some of the reasons for the disappointing performance. On the other hand, it was noted that booking for the second quarter totalled US$ 109 million, representing an all-time record for the company. However, Goldstein said, “although second quarter bookings have remained strong, continuing the pattern of the previous two quarters, delivery schedules, coupled with margin pressures in certain market segments, could cause some of these same conditions to continue,

In addition, Najade says that a novel, revolutionary system of standard units (type MU) for mixing a gas with a liquid can be implemented. For example, for the distillation of seawater at atmospheric pressure and low temperatures, fractionation and distillation of volatile components, scrubbing and/or cooling of gases, aeration of liquids. Najade will be unveiling the new membranes at stand 825 in Hall A.

Water, Cumbria, UK. It is reported that the 59 MLD continuous microfiltration system (CMF) will consist of 19 x 90MlOC microfiltration units to be housed in a purpose-built facility. The CMF equipment will be used to treat water from Ennerdale Water, to produce potable water for a local population of 60,000 and industrial water users in the Whitehaven area. Situated in a remote area of the Lake District, Ennerdale Water has been used as a source of potable water for many years. According to USF the membranes will remove algae in addition to any potential instance of cryptosporidium or other chlorine-resistant pathogens with a 99.9% potable water recovery rate. In addition, by passing the backwash water through a membrane system, the USF Memcor equipment will allow North West Water to optimise water resources while achieving maximum water quality with minimum wastage.

US$25 M upgrade for Akzo Nobel membrane plant Akzo Nobel N.V. has decided to invest US$25 million to upgrade its membrane chlorine plant in Skoghall, Sweden, with the aim of reducing the plant’s use of electricity and to cut maintenance costs. Akzo Nobel reports that the investment comprises the newest generation of membrane electrochemical cells, an evaporation unit for caustic lye, and upgrading of the, electricity supply to the plant. The new facilities are expected to come on stream in October 1999. The Skoghall plant has a capacity of 75,000 tons per year. In 1978, the Skoghall plant was the first chlorine plant in Europe to switch to using membrane technology.
