Siam Cellulose Co., Ltd. (SCL), Thailand, has ordered from Valmet, Finland, part of a major chemical pulp mill rebuild at its mill in Wangsala, Kanchanaburi province of Thailand. The value of the order is around EUR 30 million. 

The order includes an upgrade of the cooking plant and a fiberline rebuild. The new equipment delivery includes an evaporation plant, a recovery boiler, an ash leaching plant, and a non-condensable gas treatment (CNCG) collection and burning system. The rebuilt plant is planned to start up in early 2016.

"We chose Valmet based on our earlier successful experience with the Phoenix Mill's recovery boiler performance and CompactCooking G2 technology," said Surasak Amawat, managing director of Siam Cellulose. 

The existing cooking plant will be converted to Compact Cooking G2 by adding an ImpBinTM impregnation system, a decision based on the successful experience of improved pulp quality at the Phoenix mill. The rebuild of the fiberline includes installation of Delta screens, wash presses, screw conveyors, and medium consistency pumps. 

The new evaporation plant will replace the existing plant and support the need for increased pulp production. The new RECOX recovery boiler is a repeat order from SCG Paper and will replace the existing boiler and increase the pulp production capacity. The new ash leaching system will help the mill to maintain low levels of potassium and chloride.

 

Siam Cellulose is a subsidiary of SCG Paper and a leading producer of eucalyptus based pulp. SCG Paper is the largest integrated paper and corrugated containers producer in ASEAN.
