Andritz to upgrade world’s largest BCTMP system at Shandong Huatai Paper in China

International technology Group Andritz has received an order from Shandong Huatai Paper Industry Shareholding to upgrade an existing BCTMP (bleached chemi-thermo-mechanical pulp) plant to become the world’s largest mechanical pulping line for P&W (Printing & Writing) paper production at the mill in Dongying, Shandong province, China. Start-up is scheduled for the 4Q 2022.

The existing BCTMP line will be upgraded and rebuilt to become a state-of-the-art P-RC APMP- (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) system. The fiberline’s production capacity for mechanical pulp to make P&W paper grades will thus be increased from 100,000 to at least 300,000 admt/a, making it the largest in the world.

Andritz will rebuild two existing high-consistency (HC) refiners as well as the existing screw presses, disc filters and screens, and supply new equipment for all other process steps.

The upgraded mechanical pulping line will process a mixture of eucalyptus, poplar and acacia wood chips. The scope of supply also includes the basic engineering as well as the supervision of mechanical installation, commissioning and start-up.

Shandong Huatai Paper Industry Shareholding is the world’s largest producer of newsprint and the largest producer in the chlorine-alkali industry in China.
