SDK to Launch Hybrid-type PFC Decomposition System

SDK to Launch Hybrid-type PFC Decomposition System 
Tokyo, Sept 5, 2012 - (JCN Newswire) - Showa Denko K.K. (SDK) will begin
marketing a new hybrid-type system for decomposing perfluoro compounds (PFCs)
by the end of this year. The system (trade name: HB-3000) does not require a
water treatment process, helping to increase exhaust gas treatment capacity and
reduce running costs. 
PFCs are used in the process of etching LCD panels and semiconductors. As PFCs
have high levels of global warming potential (GWP), they need to be decomposed
before exhaust. SDK has developed "HB-3000" by combining the
advantages of two different decomposition systems, namely, a "chemical
capture system" and a "catalytic decomposition system." 
Under the chemical capture system, there is no need of waste water treatment,
and the amount of CO2 emissions is small. However, the running costs are high
because the system uses high-performance chemicals, which decompose PFCs and
capture fluorine-containing substances generated from the decomposition
process. Furthermore, the system's exhaust gas treatment capacity is
limited to around 200 liters per minute, due to the restrictions on the
capacity of equipment that holds the chemicals. Meanwhile, the catalytic
decomposition system involves low running costs and enables treatment of a
large volume of exhaust gas, using large-sized equipment. This is because PFCs
are decomposed with catalyst and the resulting fluorine-containing substances
are absorbed into water. However, the system needs after-treatment of waste
SDK has developed a dry-type process for removing fluorine-containing
substances under the catalytic decomposition system by introducing low-cost
calcium-based adsorbent. Advantages of the new hybrid decomposition system
"HB-3000" are as follows: 
1. As adsorbent is automatically and directly fed into the system, there is no
capacity limit due to the restrictions on the capacity of equipment that holds
the adsorbent. Thus, the exhaust gas treatment capacity is maintained at the
same level as that of a conventional large-sized catalytic decomposition system
(3,500 liters per minute). At the same time, it is now possible to build a
compact system that can be installed in a 20-foot container, as the
after-treatment process has been eliminated. 
2. Running costs pertaining to adsorbent are lower than the running costs for
the chemical capture system. Water-treatment cost is reduced, compared with the
conventional catalytic decomposition system. 
3. Calcium fluoride (CaF2), generated as a result of the capture of fluorine,
can be recycled as synthetic fluorite. 
SDK's semiconductor-processing high-purity gas business is classified in
the category of "Growth and New Growth" businesses. SDK will sell
"HB-3000" in China and other overseas markets where production of LCD
panels and semiconductors is expected to grow rapidly. SDK aims to record
annual sales of 3 billion yen in 2015 from its exhaust gas treatment equipment
