Uhde (now ThyssenKrupp Electrolysis
GmbH, a 100% subsidiary
of ThyssenKrupp Industrial Solutions
AG; Dortmund, Germany;
www.thyssenkruppindustrial -
solutions.com). When ODC is introduced
into a chlor-alkali plant, H2 is
no longer produced as a byproduct in
the electrolyzer, and the operating
voltage is reduced from about 3 V
to 2 V. As a result, energy consumption
for Cl2 production is reduced by
about 30%, says Bayer Material Sciences
(for more details, see Chem.
Eng., May 2007, pp. 50-55).
The commercial application of ODC
technology started with hydrogenchloride
electrolysis. The recovery of
Cl2 from electrolysis was initially developed
in the late 1990s by De Nora
and Uhdenora - a joint-venture (JV)
between ThyssenKrupp Electrolysis
and Industrie De Nora. Thanks
to the collaboration with Bayer, the
RG LF+SS Ad_7x4.88.pdf 1
first industrial-scale facility to use
ODC was demonstrated at Bayer's
Brunsbüttel, Germany site (Chem.
Eng., March 2004, p. 17). Since then,
Bayer has implemented ODC for HCl
electrolysis in large sites [30,000 metric-ton
per year (m.t./yr)] in Caojing
(near Shanghai), China.
The ODC technology for the chlor8/7/14
10:28 AM
alkali process was first commercialized
in June 2013 by Uhdenora. In
February 2014, Uhdenora received
its first order for this ODC technology,
and signed a contract with
Befar Group Co. for the construction
of an 80,000-m.t./yr caustic
soda plant at Binzhou City, China.
The project is being implemented in
two phases: the first phase, which
is to be commissioned in the 2nd
quarter of 2015, will have a capacity
of 40,000 m.t./yr; and the second
phase will follow shortly thereafter.
Under the JV Uhdenora, ThyssenKrupp
Industrial Solutions and
De Nora have already been cooperating
for several years in licensing
various electrolysis processes, says
Luca Buonerba, chief marketing
and business development officer,
Industrie De Nora. In November
2013 both companies agreed to
fully combine their engineering,
procurement and construction activities
for electrolysis plants - as
well as those of Chlorine Engineers
Corp. (Tokyo, Japan; www.chlorineeng.co.jp),
which became a 100%owned
subsidiary of Industrie De
Nora in 2012 - in a planned new
JV under the name ThyssenKrupp
Uhde Chlorine Engineers. This will
enable both partners to expand
their technological platforms and
move closer to customers through
increased global presence, says De
Nora's Buonerba. The agreement is
subject to approval by the relevant
antitrust authorities.
