Japanese Chemical Company Launches High-Efficiency Decomposition System for GHG

Keywords: Environmental Technology Manufacturing industry 

Showa Denko K.K. (SDK), a major Japanese chemical company, announced on September 5, 2012, that it would begin marketing a newly developed device to efficiently decompose perfluoro compounds (PFCs) by the end of 2012. PFCs are greenhouse gases used in the process of producing semiconductors and liquid crystal display (LCD) panels.

As PFCs have high levels of global warming potential (GWP), they need to be decomposed before being exhausted. Currently, there are two different systems used for decomposition; a "chemical capture system" and a "catalytic decomposition system." The chemical capture system does not require waste-water treatment, and generates less carbon dioxide, while the running costs are high and gas treatment capacity is limited. Meanwhile, the catalytic decomposition system has the advantage of lower running costs and larger gas treatment capacity. However, the system requires after-treatment of waste water.

The newly developed PFCs decomposing device, a hybrid-type system that combines the advantages of these two systems, achieved an increase in exhaust gas treatment capacity and a reduction of running costs without requiring a water treatment process.

The company plans to sell the device in China and other overseas markets where production of semiconductors and LCD panels is expected to grow rapidly, aiming to record annual sales of three billion yen (about $38.96 million) in 2015 in its exhaust gas treatment equipment business.
