ANDRITZ to supply new semi-chemical fiberline based on green liquor technology to SCG Paper, Thailand


International technology Group ANDRITZ has received an order from SCG Paper, one of Asia’s leading producers of packaging grades, to supply a semi-chemical pulp fiberline for the Wangsala mill, Thailand.

The eucalyptus fiberline will have a production capacity of 240 admt/d and provide pulp for the production of kraftliner and corrugated medium. Start-up is scheduled for the fourth quarter of 2015.

The ANDRITZ semi-chemical pulping process is based on green liquor technology. Thanks to blow-line refining at low temperature in the medium consistency range followed by low-consistency refining, high-grade semi-chemical pulp is produced economically with low energy consumption. ANDRITZ fiber washing is tailored to the specific pulp quality, and it also enables high washing efficiency and low chemical consumption.

The order comprises a complete semi-chemical pulp fiberline including chip washing, chemical chip impregnation and digester feeding with an ANDRITZ MSD Impressafiner, a continuous digester, a medium-consistency ANDRITZ 1CP blow line refiner, brown stock washing with an ANDRITZ DD (Drum Displacer) washer, and low-consistency refining with TwinFlo refiners to optimize the pulp properties.

This is already the second order within a year that SCG Paper awarded to ANDRITZ (in 2013, ANDRITZ received an order to deliver a fiberline for used paper and board packaging as well as a reject handling plant). SCG Paper has facilities in Thailand, Vietnam, and the Philippines, producing approximately 1.9 million t/a packaging paper that is certified by international environmental standards.
