Nippon Paper Industries orders chemical recovery boiler from ANDRITZ


Nippon Paper Industries Co., Ltd. has selected international technology group ANDRITZ to supply a new recovery boiler for its pulp mill in Ishinomaki, Japan. The scope of supply includes advanced automation and digitalization solutions for maximum use of the boiler’s potential.

The value of the order will not be disclosed. It is included in ANDRITZ’s order intake for the second quarter of 2025.

The new boiler, with its high efficiency and superior steam generation capacity, will enable the shutdown of one existing coal-fired boiler and two recovery boilers, resulting in a significant reduction in greenhouse gas emission, thus making mill operations more economical and sustainable. ANDRITZ will execute the project in co-operation with the Japanese EPC supplier, Kanadevia. The start-up is scheduled for 2028.

“We are very pleased that this new high-efficiency recovery boiler will make a significant contribution to reducing greenhouse gas emissions at the Ishinomaki mill. We aim to strengthen our international competitiveness by utilizing the learnings from this project at our other mills,” said Mr. Yoshinori Matsubara, Executive Officer, Head of Energy Business Div., Nippon Paper Industries. 
“We greatly appreciate the trust that Nippon Paper Industries has placed in the ANDRITZ team and our technical solutions. Our approach to the supplied technology represents the best solution in terms of process and efficiency, and operation cost. We look forward to executing this project and to extending our collaboration in the future,” said Masato Tsuchitana, General Manager at ANDRITZ in Japan.

ANDRITZ’s scope of supply includes the following new equipment:
• A new recovery boiler designed for a capacity of 2,200 tds/d with steam parameters of 8.3 MPa and 505 °C. Designed for long operating periods, the state-of-the-art boiler features several automation and digitalization solutions.
• A high-dry solids concentrator with pressurized storage tanks is used in the evaporation plant to increase the firing black liquor’s dry solids concentration, thereby maximizing recovery boiler efficiency.
• An ash leaching system to remove chloride and potassium from the electrostatic precipitator’s ash while recovering sodium and sulfate to the chemical recovery cycle.

With this order, ANDRITZ once again demonstrates its strong global position as a supplier of state-of-the-art pulp mill technology focusing on environmentally friendly production.
