Press Release Body: LCD flat screens: FEBEX and SULZER announce the development of a competitive phosphoric acid recycling process.
A joint offer for the flat screen (LCD) industry.
BEX and BUCHS (Switzerland), 26 November 2007
FEBEX and SULZER have announced the successful development of a competitive process for the recycling of spent phosphoric acid used in the manufacture of flat screens.
FEBEX, Europe's leading manufacturer of ultra-pure phosphoric acid for electronics, and SULZER CHEMTECH, a world-renowned specialist in separation, mixing and purification technology, announced the creation of a cooperation venture in this area in November 2006.
Following several months' work, lengthy testing and hundreds of analyses, both companies are now in a position to announce that they have developed a unique process to recycle this waste phosphoric acid, which has a very high aluminium and molybdenum content. A joint package will be offered to LCD flat screen manufacturers in Asia and the rest of the world. This highly cost-effective solution fulfils manufacturers' requirements more efficiently as regards the recycling of phosphoric acid from the manufacture of liquid crystal display (LCD) flat screens.
This unique process offers end-users a phosphoric acid with the same physico-chemical characteristics as the initial acid due to an excellent purification yield. It consists of a high-tech series of fully-computerised purification operations based on crystallisation.
\"This process is clearly intended to operate in close proximity to end-users,\" stated Thierry VASSALO, FEBEX General Manager, \"if not on their actual production sites, as in the case of the recycling of organic solvents. It should afford a very significant reduction in the purchasing cost of phosphoric acid for flat screen manufacturers\".
\"Our agreement with Febex is essentially based on the combination of our process guaranteeing the very latest purification techniques, for which SULZER is the world's leading specialist, with Febex's process and product expertise\", added Manfred STEPANSKI, SULZER Technical and Sales Manager.
