Linde Gases, a division of The Linde Group, has announced it will construct ECOVAR^TMstandard on-site nitrogen and oxygen production plants for CP Kelco and Metsä Fibre,respectively, in Äänekoski, Finland. The long-term on-site gas supply agreements include plant installation, operation and maintenance. Both plants will be constructed by Linde’s Engineering Division.

The nitrogen production installation at CP Kelco will incorporate Linde’s ECOVAR^TM ADSOSS^TM-N gas generation plant, which separates nitrogen from air employing the adsorption-based PSA (pressure swing adsorption) process. The customer uses nitrogen for inerting processes in the production of CMC (carboxymethyl cellulose) in order to control the level of oxygen content.

The uninterrupted supply of nitrogen is of primary importance to the production process, product quality and operational safety. To guarantee CP Kelco a continuous supply of nitrogen under all conditions, a back-up system based on vapourisation of liquid nitrogen will also be installed. Implementation of the ECOVAR^TMplant is underway, with operations beginning early 2016.

Linde has also agreed with Metsä Fibre, part of Metsä Group, long-term deliveries of oxygen based on a similar ECOVAR^TM supply concept, this time incorporating an ADSOSS^TM-O oxygen plant. The plant will extract oxygen by means of adsorption. ADSOSS^TM-O gas generation plants are typically designed with two cyclically operated adsorber vessels to extract oxygen continuously, known as vacuum pressure swing adsorption (VPSA) technology.

The installation will be built in the Metsä Group´s new bioproduct mill area, currently under construction. Oxygen is an essential chemical in the modern pulp mill and its uninterrupted delivery is vital. Metsä Fibre uses significant amounts of oxygen in its processes, for example, in the bleaching of pulp and oxidation of white liquor.

The Äänekoski ADSOSS^TM-O oxygen plant will be one of the world’s largest oxygen plants based on VPSA and will begin operations at the same time as Metsä Group’s bioproduct mill in the third quarter of 2017.

“We are delighted to be able to contribute, through our expertise, to this new EUR 15 million investment project for the pulp and paper industry in Finland. Gases are an essential part of many production processes in this industry and these particular investments are an important focus for growth. The new bioproduct mill will create further opportunities for both our gases and gas technologies. As such, we have a commitment to our customers to continue to develop technologies and delivery concepts which improve the efficiency, productivity and sustainability of their processes,“ said Bo Dyrvold, Head of Linde’s Regional Business Unit Northern Europe.

The ECOVAR^TM delivery method is the most efficient way to deliver large amounts of gases for industrial processes, both in terms of energy consumption and a reduction in environmental impact. On-site production significantly reduces the need for road deliveries of gas and adsorption technology also saves energy compared to cryogenic distillation, commonly used in production of gases in large quantities. The plants are fully automated and operations are monitored from the company’s remote operation centre in Avesta, Sweden.

With the delivery of two fuel-cell trucks to the Linde Gases Division, part of technology company The Linde Group, Linde Material Handling has taken another important step on the road to more intensive use of innovative drive technology. As the first industrial truck manufacturer in Europe, Linde MH has incorporated fuel cell trucks into its product range. The trucks are now offered as standard and with immediate effect, as a "Customised Option".

Both fuel-cell trucks are based on the 3-tonne electric counterbalanced truck, the Linde E30. In addition, the enhanced beverage industry version offers an optimised view over the load. In place of the usual 80-volt battery, the trucks have a fuel cell and a tank, which stores 1.6 kilograms of hydrogen gas at 350 bar. The electricity generated from the hydrogen supplies the electric motors that drive the truck. Alongside this are so-called supercaps, large condensers, which act as a buffer and cover performance peaks, such as pulling away or lifting, for example. The trucks bear the CE mark and are permitted for use on public roads. When it comes to performance data, the trucks are not different to the equivalent battery-powered model in the range and they are tailored specially to Linde Gas' customer requirements.

The fuel-cell trucks were developed over the last two years with long-term partner, Hydrogenics, the Canadian fuel cell manufacturer. Linde's contractual partner, Gruma Nutzfahrzeuge, based in Garching, near Munich, has been involved with the project from the beginning and is responsible for all issues related to servicing and maintaining the trucks. One of the trucks is used by Linde Gas for transporting Gas bottles between production halls and the truck embark point, which involves crossing a public road. The second fuel-cell truck operates in the field of gas bottle filling. Both trucks replace diesel trucks with a
3.5-tonne load capacity, which were previously used for this purpose. Filling up the fuel-cell trucks is quick and safe at the Linde hydrogen centre filling pump and is therefore comparable to filling a conventional truck.

The benefit of the fuel-cell drive for Linde Gas is the "zero emissions" that these trucks produce when used. The only waste product from the splitting of hydrogen molecules is pure water. Another benefit of fuel cells, in comparison to other drive concepts, is that there is no longer a requirement for battery replacement or a battery charging process lasting a number of hours. In the same way, the safety risks relating to the use of battery acid are removed. In order to be able to use the trucks, drivers only require an extra hour and a half driving lesson, along with a valid forklift licence for the advanced trucks.
