Global Filter launches new filter vessel line Band Clamp Vessel Line as an improved version of current band clamp style vessels on the market, but also as a drop-in-replacement for these existing units.

The GTCHB Series Band Clamp Cartridge Filter Vessel Line from Global Filter, LLC.

US-based Global Filter, LLC has introduced the GTCHB Series

“In early 2009 Global Filter began a study to understand the trends and requirements of various filter vessels in both the North American and European markets,” explains Todd Younggreen, president of Global Filter, LLC. “We had begun making market share gains through the introduction of our ASME designed bag and cartridge vessels. However, with the addition of our new 30,000 square feet warehousing facility in Cedar Rapids, Iowa, we were able

to explore the potential of other stainless vessel lines.” Global Filter says that while it was looking to improve the quality and durability of the ‘band clamp’ style vessels, it was also essential to maintain an identical footprint to what was already being sold in the marketplace. Todd Younggreeen adds: “Through discussions with many OEM buyers of band clamp style units, we knew that several improvements were required, which we incorporated in the new GTCHB Vessel Line.” These improvements included a heavier wall thickness for a more robust unit, and improved

lid sealing through the use of an optimum lid profile. DOE/222 Universal Cups are standard on all GTCHB vessels and all units accept 2.5 in. (6.35 cm) wound and meltblown cartridges in addition to 2.7 in. (6.86 cm) pleated cartridges. In addition, legs are standard on all units. “We recognise the pressures on OEMs to limit inventory costs, and that key to our success would be rapid shipment,” says Todd Younggreen. “With this in mind, our new warehousing and training facility maintains a stock of over 300 vessels ready for same day shipment.” www.globalfiltercorp.com

Next phase for successful CO2 scrubbing test

A research project for CO2 scrubbing, conducted by RWE Power, BASF and Linde, has been successful enough for the companies to launch the next phase of development.

Preliminary tests of the scrubbing technology resulted in a separation efficiency of 90%, high purity and much lower energy input, according to reports. The original pilot plant was commissioned in 2009 at the coal innovation centre in Niederaussem, a lignite-fired power station owned by RWE and based in Germany. The technology will now undergo a long-term test until the end of 2013, with €6 million invested in

the project, of which €4 million comes from Germany’s Federal Ministry of Economics and Technology.

Different scrubbing agents were initially tested in three test phases of six months each as part of the pilot operation of the CO2 scrubbing plant connected at the Niederaussem plant. The aim was to identify an optimum solvent developed by BASF. The researchers found that, when compared with current processes commonly used, the energy input can be reduced by about 20% when using the new chemical solvent for CO2 capture. The new scrubbing agent also comes with significantly increased stability and resistance to oxygen. In

the test phase starting now, the structure of the CO2 absorber, where the CO2 is removed from the flue gas, will be improved by scientists from Linde so that carbon dioxide can be removed even more effectively from the flue gas. If the test is successful, CO2 absorbers for large-scale power plants be made smaller more cheaply.

“Efficient CO2 scrubbing is key to the success of carbon capture and storage technology, i.e. the removal and storage of carbon dioxide,” said Dr Johannes Lambertz, CEO of RWE Power. “Together with our partners, we want to move [the process] forward as an enabling technology for low-polluting

electricity generation from coal. The politicians also have to do their bit: we need a CCS law implementing the requirements of the EU Directive without any special conditions to enable the technology to be used in Germany in the long run.” “As we continue this highly successful cooperative venture, we are very confident that we will further optimise and develop this technology to have it ready for commercial use by 2013,” add Dr. Stefan Blank, senior vice president in BASF’s Intermediates division. www.rwe.com www.basf.com www.linde.com

pump for standard applications; one with an over-pressure pump for contaminated samples; and one with a hose.

The company says that it is a portable instrument for determining air permeability in both the testing laboratory and mobile environments. It is claimed to be particularly suitable for

According to Textest, the instrument works in accordance with many national and international standards. The MOBILAIR comes in three versions: one with a vacuum

In operation, the test specimen is placed over the test head opening. By pressing down the clamping arm the sample is clamped in place, the pump is started and the pre-selected

test pressure across the sample is automatically maintained. The air permeability of the test specimen is determined from the pressure drop across a variable orifice. The company adds that high precision pressure sensors provide highly accurate and reproducible test results. www.textest.ch
