thyssenkrupp Uhde has won an order from Nippon Coke & Engineering Co., Ltd. (NCE) to build and supply a new low-emission, top-charge coke oven battery in Japan. The new battery will be installed at the Kitakyushu works as a replacement for the existing battery 2A. The design will include thyssenkrupp Uhde’s proprietary EnviBAT® system to reduce emissions during the coking process.
“With this state-of-the-art, low-emission plant, NCE and thyssenkrupp Uhde are delivering an important contribution to making the Japanese coke plant industry more environmentally friendly,” says Michael Petzinna, Executive Director of the Coke Plant & Inorganic Acids operating unit. “We look forward to continuing our collaboration and are proud to be contributing our decades of plant engineering and process know-how to the project.”
The project is part of the modernization of NCE’s coke plants, which involves four coke oven batteries built in the 1970’s being shut down and replaced by new, state-of-the-art, low-emission systems. Worth an amount in the double-digit million-euro range, the contract includes the provision of the technology and engineering, equipment procurement, supervision of construction and commissioning of the new plant.
“In thyssenkrupp we have selected a reliable partner for the EP pad-up project. The company combines extensive plant engineering experience with efficient technologies that meet and exceed the most exacting environmental standards,” said Mr. Hiroaki Matsuoka, Representative Director & President of Nippon Coke & Engineering at the contract signing.
EnviBAT® individual chamber pressure regulation system reduces emissions
thyssenkrupp Uhde’s EnviBAT® individual chamber pressure regulation system is already in use in more than 30 batteries and thus over 2,100 coke ovens around the world. Constant, intelligent pressure monitoring and adjustment throughout the coking process minimizes emissions effectively. EnviBAT® prevents high gas pressures arising in the individual oven chambers of the batteries at the start of the coking process, which in turn almost completely eliminates emissions through all oven closures and the gas collecting main. Further efficient measures such as flexible, spring-loaded door systems, water-sealed standpipe lids and the CONTROLPRESS™ bracing system are all geared toward preventing emissions from the battery and ensuring an optimized operation.
