Chung Hwa Pulp Corporation selects Andritz to supply chemical recovery technologies for its pulp mill

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.
• A new ash leaching plant integrated into the recovery boiler, with a capacity of 108 t/d. The plant will reduce chlorine and potassium levels but also recover valuable chemicals.
• An energy efficient black liquor evaporation plant with a capacity of 377 t/h. Andritz’s easy-to-clean lamella heating surfaces ensure high availability and easy operation. The evaporation plant includes also advanced process controls.

This is the first Andritz chemical recovery technology delivery to Taiwan. Chung Hwa Pulp Corporation (CHP) is a Taiwan-based company established in 1968. The company focuses on the manufacture and sale of pulp and paper and related products.
