Valmet is to supply a CompactCooking G2 pulp cooking system to Siam Cellulose's pulp mill in Ban Pong, Thailand.
Siam Cellulose already operates two CompactCooking plants at its mills in the country.
The 2-vessel continuous cooking system will replace existing tube digesters at the mill, which is capable of producing close to 70,000 tons of eucalyptus pulp annually.
The plant with ImpBin for impregnation and a digester for cooking of chips will be able to chemically separate lignin from fiber to produce pulps with high yield and excellent pulp quality. It will become operational in December next year.
Valmet sales manager Patrik Lidbck said: "We are very pleased to continue our successful cooperation with Siam Cellulose.
"The new cooking plant will replace the existing tube digesters and will utilize the raw material more efficiently, improve pulp quality, save chemicals and all in all improve the environmental performance of the mill."
Valmet said that the ImpBin technology enables higher kappa level still with low reject content.
Siam Cellulose is a subsidiary of SCG Packaging, which is said to be the largest integrated paper and corrugated containers producer in ASEAN.
Earlier this month, Valmet agreed to supply a CompactCooking G2 system to bleached paperboard and pulp company Clearwater Paper's mill in Lewiston, in the US state of Idaho.
Valmet had also agreed to deliver a new plant for generating polysulfide and a minor upgrade of Clearwater's existing bleach plant.
