Hitachi Zosen Receives SCR System Order for Tier III NOx Compliance

Thursday February 16, 2017

Hitachi Zosen Corporation (Hitachi Zosen) Tuesday announced that it received an order from China's Dalian Marine Diesel Co., Ltd. (Dalian Marine Diesel) for two units of its high-pressure selective catalytic reduction (SCR) system, set to be installed on a 7,999 DWT chemical tanker for Tier III NOx compliance.

The first unit is slated for delivery in October 2017, while the second unit is scheduled for delivery in November 2017.

"This represents the first commercial order for exhaust gas removal equipment compliant with Tier III NOx emission standards taking effect in January 2016 by one of Japan’s leading manufacturers of large marine diesel engines," explains the company.

Tier III NOx emission standards, set by the International Maritime Organization (IMO), require marine vessels to reduce NOx emissions by 80 percent compared to Tier I standards.

"The world’s first marine SCR system developed by Hitachi Zosen uses a catalyst to render harmless NOx contained in the exhaust of diesel engines during operation," says the company.

"Hitachi Zosen is globally the only manufacturer of both large marine diesel engines and catalysts, and through in-house production realises an ideal balance between compactness of the system itself and of catalyst volume, and the performance of catalytic activation."

It is noted that the chemical tanker is being built at AVIC Dingheng Shipbuilding Co., Ltd. (AVIC Dingheng Shipbuilding)
