Chinese Delegation visits Johnson Matthey
A delegation from Peking thermal power station Beijing Yire recently accepted the invitation of Redwitz-based Johnson Matthey Catalysts (Germany) GmbH and paid the company a visit. The seven-strong delegation consisted of Deputy General manager Mr. Xu and other managers from different areas of the company.
Johnson Matthey supplied the Peking company with SINOx® plate-type catalysers for two power station blocks in 2009 and 2010. The power station originally only had one non-catalytic system (SNCR = Selective Non Catalytic Reduction), which could no longer cope with the heavy demand, as air quality measurements had revealed. In order to comply with the NOx emission standards that apply in Peking, the leading management at Beijing Yire decided to supplement the SNCR system with an SCR system (SCR = Selective Catalytic Reduction). During this process, upon which the SINOx® catalysers from Johnson Matthey are based, the nitrogen oxides are mixed with a reduction agent (aqueous urea or ammonia solution) and converted into harmless nitrogen and water in the catalyser without adverse secondary reactions.
In collaboration with plant construction company Zhejiang Rongzhi Power Technology Co. Ltd., Johnson Matthey assisted Beijing Yire with the renovation of Unit 3 and Unit 4. The catalysers were installed on schedule. As well as being highly efficient, the low pressure loss of the SINOx® plate-type catalysers was an important selection criterion for the customer. Both units went through commissioning, trial running, testing and acceptance without problems, and have been operating efficiently. The SCR system has improved the air quality considerably. "We are delighted to have been able to solve this difficult task with our SCR catalyser", emphasises Dr. Wolfgang Schüttenhelm, Director Worldwide of the Power Plant Industries Division at Johnson Matthey and responsible for the catalyser business in the power station and industry area.
Dr. Schüttenhelm welcomed the members of the Chinese delegation to Redwitz and introduced them to the company. The delegation was then given an insight into catalyser production during a tour of the manufacturing area. The visitors were particularly interested in the applicable testing standards.
About Beijing Yire
The "CLP Guohua Power Beijing Thermal Power Branch" thermal power station (otherwise known as Beijing Yire), with a general capacity of 400 MW, belongs to Peking based "Guohua Electric Power Corporation Ltd", which was established in 1999.
Beijing Yire is responsible for supplying power for the power system in northern China, and provides a fifth of Peking's main energy. The company is also responsible for providing industrial gas to the eastern part of Peking, including areas such as government organisations, ministries, embassies, diplomat accommodation, trade companies and residential buildings in the vicinity of "Tian An Men" square. Beijing Yire plays an important part in Peking's heat resources and its power supply.
Following the successful running of the Olympic Games the Chinese government has been taking a closer look at protecting the environment, an area in which the capital city of Peking has played a pioneering role.
