Chuetsu Pulp & Paper, one of the largest pulp & paper
producer in Japan has selected BTG to support its journey to improve the
bleaching process in two of its bleaching lines by implementing
MACSbleach project to optimize the bleaching chemicals usage.
Thanks
to BTG expertise and close customer interaction, the bleaching chemical
costs have been reduced by 10-15% – twice the target at the beginning of
the project. In parallel, the variability of the pulp brightness
reduced by 20-50%, which in turn has helped stabilize overall bleached
pulp quality inspite of incoming raw material and process disturbances.
This
project was conceived early in 2019 with a target to improve pulp
quality stability and to lower the bleaching costs at two of its
hardwood pulp mills at Takaoka and Sendai. BTG solution involved
combination of unique bleach plant measurements (e.g. Total Kappa,
Lignin & HexA Kappa, Brightness) and model predictive controls
MACSbleach to automate the process to be able to automatically respond
to incoming variabilities and yet maintain a more stable pulp quality.
Very close cooperation and proactive interaction between the BTG and
Chuetsu project teams resulted in completing the implementation of the
project in a record time and yet achieving all KPI’s.
A key success
factor was the user friendliness of BTG MACSbleach interface which
allowed operators to clearly visualize what happens in the different
parts of the process in real time and transparent manner through
dataPARC platform. BTG application experts provided due assistance
through off-site and on-site interaction with the operators to
constantly optimize the process.
“Thanks to their strong expertise in
unique bleach plant measurements, advance process controls and
application expertise combined with their unique customer interaction,
BTG delivered solid benefits in bleaching process optimization project,
which allows us to operate more efficiently and enhances our
competitiveness. We look forward to co-operating further with BTG to
introduce MACS to other process areas” says Mr Takado, General Manager,
Chuetsu HQ.
“BTG were honored to be selected by Chuetsu Pulp to
execute Advanced Process Control projects at their Takaoka and Sendai
fibrelines. The collaborative approach taken by the Chuetsu and BTG
teams was key to delivering the projects on time and meeting performance
guarantees. This project is the continuation of a long-term partnership
with Chuetsu and we look forward to working with this valued customer
in delivering future process improvement initiatives” shares Keith
Waters, General Manager, BTG Group, ASPAC
