Asia-based packaging paper producer SCG Paper has ordered from Andritz, Graz, Austria, a semichemical pulp fiberline for its Wangsala mill in Thailand. The eucalyptus fiberline will have a production capacity of 240 a.d. metric tpd and provide pulp for the production of kraftliner and corrugating medium. Startup is scheduled for the fourth quarter of 2015. 

 

The Andritz semichemical 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 semichemical pulp is produced economically with low energy consumption. Andritz fiber washing is tailored to the specific pulp quality, and also enables high washing efficiency and low chemical consumption.

 

The order includes a complete semichemical 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 the second order within a year that SCG Paper has 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 metric tpy of packaging paper that is certified by international environmental standards.
