ANDRITZ, an international technology group, has opted for Chung Hwa Pulp Corporation (CHP), one of Taiwan’s top pulp producers, to modernise its technology at its pulp mill in Hualien, Taiwan. Providing state-of-the-art, ecologically friendly chemical recovery methods that will greatly increase the mill’s operational effectiveness while lowering its environmental impact is the main goal of this collaboration. In the second quarter of 2027, the newly supplied technologies are anticipated to be put into service.
The technological enhancements provided by ANDRITZ include a range of advanced systems aimed at boosting the mill’s renewable energy production, reducing emissions, and optimising the chemical recovery process. The scope of supply covers several key components, each tailored to meet the growing demands for sustainability in the pulp and paper industry. The centerpiece of the ANDRITZ supply is a new recovery boiler with a capacity of 1,400 tds/d (tonnes dry solids per day), designed to operate at steam parameters of 105 bar(a) and 515°C. This high-tech recovery boiler will not only improve chemical recovery efficiency but will also allow the mill to generate more renewable energy while keeping emissions at a minimum. The boiler also incorporates digitalisation features such as advanced process controls, enabling smarter management of the mill’s operations.
A significant component of the project is the Lo-NOx recovery boiler solution, which is designed to minimise dust and nitrogen oxide (NOx) emissions during the chemical recovery process. This cutting-edge technology is a key part of ANDRITZ’s CircleToZero initiative, which aims to achieve zero emissions and zero waste production. This initiative aligns with Chung Hwa Pulp Corporation’s sustainability goals, which include reducing environmental impact while maximising operational efficiency. The Lo-NOx recovery boiler solution is specifically engineered to maintain high energy efficiency, addressing the critical need for reduced emissions in the pulp and paper industry, a sector traditionally known for its environmental challenges.
In addition to the recovery boiler, ANDRITZ will provide a new ash leaching plant integrated into the recovery system. With a capacity of 108 t/d, the plant will serve a dual purpose: it will reduce harmful levels of chlorine and potassium in the recovered chemicals while also enabling the recovery of valuable chemicals. This will not only contribute to the mill’s sustainability efforts but also reduce operational costs by recovering and reusing valuable resources. The ash leaching plant is another example of how ANDRITZ’s solutions help mills move towards more circular processes, where waste is minimised and resources are maximised.
ANDRITZ will also supply a black liquor evaporation plant with a capacity of 377 t/h. Black liquor, a byproduct of the pulping process, is typically rich in chemicals that can be recovered and reused in the mill’s operations. The evaporation plant supplied by ANDRITZ features easy-to-clean lamella heating surfaces, ensuring high availability and low maintenance needs. This will significantly reduce downtime and make operations more efficient. Like the other technologies being supplied, the black liquor evaporation plant will also benefit from advanced process controls, allowing for seamless monitoring and optimisation of the evaporation process.
This order marks ANDRITZ’s first chemical recovery technology delivery to Taiwan, showcasing the company’s expanding footprint in the Asia-Pacific region. As a global leader in pulp and paper technology, ANDRITZ’s innovative solutions have been instrumental in transforming the pulp and paper industry towards more sustainable and eco-friendly practices. For Chung Hwa Pulp Corporation, the collaboration with ANDRITZ represents a significant step towards future-proofing their Hualien mill operations. Project Manager Chang Mingyih expressed his enthusiasm about the partnership, stating, “The equipment and solutions from ANDRITZ will enable us to maximise our mill’s operational efficiency while minimising resource use and maintaining low emission levels.”
The dedication of Chung Hwa Pulp Corporation to environmentally friendly pulp and paper manufacturing
Founded in 1968, Chung Hwa Pulp Corporation is a Taiwan-based company specialising in the production and sale of pulp and paper products. The company has been at the forefront of adopting sustainable practices in the pulp and paper industry and continues to prioritise environmentally friendly solutions to meet the growing demand for eco-conscious production methods. With this new project in Hualien, CHP further solidifies its commitment to responsible and sustainable pulp production. By incorporating ANDRITZ’s advanced technologies, CHP is positioning itself as a leader in the environmentally responsible manufacturing of pulp and paper products in Taiwan. These technologies will not only improve the mill’s overall sustainability but also contribute to Taiwan’s broader environmental goals.
This partnership between Chung Hwa Pulp Corporation and ANDRITZ represents a major leap forward for the pulp and paper industry in Taiwan. The state-of-the-art technologies set to be installed at the Hualien mill will help the industry move towards more energy-efficient, low-emission production processes, aligning with global trends in sustainable manufacturing. With the start-up of these technologies scheduled for 2027, Taiwan’s pulp industry is poised to benefit from a greener, more efficient future, paving the way for other mills to follow suit in adopting sustainable technologies.
