thyssenkrupp wins order from China for low-emission coke oven batteries

thyssenkrupp’s chemical plant engineering business has won an order from XiaoYi JinHui Coal & Chemical Co. Ltd. to build and supply two new low-emission, stamp-charged coke oven batteries in China. The new batteries will be installed at Wutong Coal Chemical Park in Xiaoyi, around 650 km southwest of Beijing, to replace an existing facility. They will include thyssenkrupp’s proprietary EnviBAT® system to reduce emissions during the coking process as well as the Cokemaster® automation system for optimized production processes.

“With this state-of-the-art, low-emission plant, XiaoYi JinHui and thyssenkrupp are delivering an important contribution to making the Chinese coke plant industry more eco-friendly,” says Uwe Boltersdorf, Chief Sales Officer of the Chemical & Process Technologies business unit. “We look forward to continuing our collaboration and are proud to contribute our decades of plant engineering and process know-how to the project.”

The project is part of the modernization of the Chinese coke plant industry in which old plants are being shut down and replaced by new, state-of-the-art, low-emission systems. Worth an amount in the two-digit million euro range, the order comprises the provision of the technology and engineering, procurement of equipment and monitoring and commissioning of the new plant. Parts of the engineering will be realized by the Chinese company Sedin Ningbo Engineering Co. Ltd. CNCEC.

“In thyssenkrupp we have selected a reliable partner for our investment project. The company combines extensive plant engineering experience with efficient technologies that meet and exceed the most exacting environmental standards. Together we will play a part in driving the sustainable modernization of the chemical industry in China,” said the project chief commander of XiaoYi JinHui at the contract signing.

EnviBAT® single-chamber pressure regulation system reduces emissions

thyssenkrupp’s EnviBAT® single-chamber pressure regulation system is already in use in more than 30 batteries and thus over 2,100 ovens around the world. Constant, intelligent pressure monitoring and adjustment throughout the process optimizes raw material use and minimizes emissions. EnviBAT® prevents high gas pressures arising in the individual chambers of the batteries at the start of the coking process, which in turn almost completely eliminates emissions through the oven doors or roof. Further efficient measures such as flexible, spring-loaded door systems and water-filled rising pipe covers are all geared toward preventing emissions from the battery.

Optimized production with Cokemaster®

The entire production process can be automated and optimized using the Cokemaster® system developed by thyssenkrupp. The integrated system comprises various stand-alone modules that can also be used for individual applications. They include for example automatic temperature measurement in coke ovens, a dynamic calculation model for thermal energy and other solutions along the entire production chain. Cokemaster® can also be retrofitted in existing plants.
