Chung Hwa Pulp Corporation has awarded international technology group ANDRITZ an order to supply environmentally leading chemical recovery technologies for its pulp mill in Hualien, Taiwan. The start-up is scheduled for the second quarter of 2027.
Project Manager Chang Mingyih at Hualien mill of Chung Hwa Pulp Corporation said: “The equipment and solutions from ANDRITZ will enable us to maximize our mill’s operational efficiency while minimizing resource use and maintaining low emission levels.”
The ANDRITZ scope of supply includes:
- A new recovery boiler designed for a capacity of 1,400 tds/d with steam parameters of 105 bar(a) and 515 °C. The state-of-the-art recovery boiler will enable efficient chemical recovery at low emissions and significantly increase the mill’s renewable energy production. The boiler features digitalization products such as advanced process controls.
- Lo-NOx recovery boiler solution to achieve minimum dust and NOx emissions from the boiler while maintaining high energy efficiency. This solution is part of ANDRITZ’s CircleToZero initiative, which aims for zero emissions and zero waste production.
