Contract in South Korea for three tail gas treatment units for the abatement of greenhouse gases
First approved CDM methodology for the reduction of nitrous oxide emissions from nitric acid plants
The South Korean company, Carbon CDM Korea Ltd. of Seoul, a subsidiary of Carbon Projektentwicklung GmbH of Austria, has commissioned Uhde to design and supply key components for three tail gas treatment units based on the EnviNOx® technology. The EnviNOx® units will be installed in three existing nitric acid plants built by Uhde for Hu-Chems Fine Chemical Corp. at Yeosu, some 300 km south-east of Seoul. The contract includes the licence, engineering, supply of key equipment and supervision of the commissioning activities. The units are scheduled to come on-stream in early 2007.
Uhde's EnviNOx® process uses a special catalyst to convert the pollutant nitrogen oxides, i.e. nitrous oxide (N2O) and NOx, in the tail gas streams of nitric acid plants into the naturally occurring substances nitrogen, oxygen and water vapour.
Future annual emissions at the Yeosu plants will be reduced by approximately 4,800 tonnes of nitrous oxide. As the global warming potential of nitrous oxide is estimated to be 310 times that of carbon dioxide (CO2), this corresponds to a CO2 reduction of approximately 1.5 million tonnes per year.
Uhde's new contract is embedded in a project for the achievement of climate protection goals based on the Clean Development Mechanism (CDM) defined in the Kyoto Protocol.
