Andritz starts up semi-chemical pulp line with green liquor pulping technology at APPM in Russia

Feb 02, 2016. /Lesprom Network/. International technology Group Andritz has started up the pulp line delivered to JSC Arkhangelsk Pulp and Paper Mill (APPM) at the Novodvinsk mill, Russia. The new line features Andritz green liquor technology for efficient pulp cooking, refining, and washing and produces 1,000 t/day of semi-chemical pulp for the production of corrugated board from birch and aspen, as the company says in the press release received by Lesprom Network.

Semi-chemical pulp is produced in a combination of mild chemical treatment and subsequent mechanical treatment in which the fibers are liberated from the wood matrix.

A major advantage of the Andritz green liquor technology, which is mainly applied for hardwoods and enhances the fiber quality substantially, is the efficient and easy recovery of cooking chemicals in the adjacent kraft mill. Thus, no additional process steps are needed for chemical recovery.

With this new line, the production capacity of APPM has doubled, while productions costs and waste water volume have been substantially reduced.

Andritz Pulp & Paper is a leading global supplier of equipment, systems, and services for the production and processing of all types of pulps, paper, tissue, and cardboard.
