GREECE – Unipak Hellas, an integrated paper and packaging company, has recently invested in KPM KC7 microwave consistency sensors from ABB, a leading automation company, for its new paper mill in Pelasgia, Greece.
These sensors employ microwave true-phase technology to deliver precise total consistency measurement of various pulp types, including mixed pulps and those with fillers, regardless of flow rate, thereby enhancing process control.
By utilizing this cutting-edge technology, mills can achieve representative, accurate, and reliable measurements that remain unaffected by process variables or obstructions.
Moreover, the sensors feature a transmitter with no moving parts, ensuring high equipment uptime and minimal maintenance requirements.
The inline, dual-plate design of the sensors includes an optional retractable temperature sensor for challenging processes, while the flow-through model accommodates pipes of up to 16″ diameter.
Microwave consistency sensors offer versatility, making them suitable for a range of applications, including blend/mixing chests, machine chests, and recycled pulps with varying qualities such as freeness, kappa, and ash content.
Erik Teunissen, ABB’s area sales manager, expressed optimism about Unipak Hellas’s adoption of this technology, highlighting the benefits of solving consistency problems with a single sensor type.
Jihad Hasrouni, division process improvement manager at Unipak Hellas, emphasized the company’s commitment to enhancing production capacity for recycled corrugated case material at the Pelasgia mill, including testliner and recycled fluting grades.
Notably, this marks the first instance where a customer has opted to exclusively use microwave technology throughout an entire facility, showcasing a progressive approach to process optimization.
In another development, ABB recently secured a significant role as a project partner for the installation of Gascogne Papier’s state-of-the-art uncoated machine-glazed (MG) paper machine in Mimizan, France.
This project involves the overhaul of the PM7 machine, utilizing ABB’s advanced technologies such as the System 800xA distributed control system (DCS) and Quality Control System (QCS) tailored for pulp and paper applications.
The integration also includes ABB drives and motors, designed to facilitate automatic grade changes and multi-variable cross-directional controls, ultimately enhancing operational efficiency.
This comprehensive package not only aids in energy conservation but also optimizes paper production, reducing waste and ensuring higher quality output.
The scope of ABB’s technology implementation extends to the new paper machine, boasting a remarkable web width of 6.8 meters and a design speed of 1,300 meters per minute.
