The value of the order will not be disclosed. However, a project of this size and scope is typically valued at around EUR 140 million. The order was included in Valmet’s orders received of the second quarter 2021.
“This project is the result of good cooperation between Nine Dragons and Valmet to find the optimum mill concept solution. I am happy to say that the outcomes are state-of-the-art process solutions, which will allow Nine Dragons to produce high-quality pulp grades in a more sustainable way with excellent efficiency in energy and raw material utilization. We are committed to continuing to support Nine Dragons with the latest technology and strong local presence in China,” says Zhu Xiangdong, Area President, China, Valmet.
Valmet’s delivery includes two fiberlines, two BCTMP lines, a recovery boiler and DeNOx scrubbers for recovery boiler and lime kiln with the corresponding spare part packages.
The fiberlines will provide Nine Dragons with the flexibility to produce pulp grades of different types. The new fiberlines provide possibilities to optimize pulp properties with lower power and wood consumption. This allows Nine Dragons to achieve excellent resource efficiency. The deliveries include Valmet Continuous Cooking G3, Valmet Screening, Valmet Refiner and Valmet Washing, Oxygen and Bleaching technologies.
The BCTMP lines include impregnation system, high consistency refining, bleaching system, low consistency refining, screening, dewatering and washing. It is designed to provide high yield, low energy consumption, and excellent pulp quality for the new paper machines.
The recovery boiler has multiple high-power features, including multi-stage preheating of feedwater and heat recovery from flue and vent gases to combustion air. The boiler is designed for low emissions and high availability. The boiler also includes non-condensable gas (NCG) incineration. In addition, the delivery includes safety-related systems and Boiler Diagnostics System for the recovery boiler.
The DeNOx scrubbers for the recovery boiler and lime kiln are equipped with chemical feeding in order to achieve very low NOx emissions. The process can reduce emissions under the required 50 mg/Nm3 level with high availability and low maintenance need.
