Andritz to supply key production technologies for Metsä Fibre’s mill in Äänekoski, Finland

Feb 13, 2015. /Lesprom Network/. International technology Group Andritz has signed a letter of intent with Metsä Fibre to deliver key production technologies for a new bio-product pulp mill with an annual capacity of 1.3 million tons of pulp in Äänekoski, Finland. The order value for Andritz is over Euro 100 million. Start-up of the planned mill is scheduled for August 2017, as the company said in the press release received by Lesprom Network.

A complete wood processing plant with three debarking and chipping lines, three stacker-reclaimer chip handling systems, and bark handling.

A softwood and hardwood fiberline comprising a chip feeding system, a two-vessel continuous cooking plant, a new evaporation system for liquor extraction, and seven DD (Drum Displacer) washers for brownstock washing and bleaching. The softwood capacity of this line will be the highest in the world by far (3,900 tons per day).

The world’s most energy-efficient black liquor evaporation plant with the highest capacity in Europe (1,650 tons/hour). The plant will have seven stages and concentrate black liquor to the very high dry solids content of 85% for efficient combustion in the recovery boiler. In addition, Andritz will also deliver chloride removal systems to enhance the chemical recovery process and to produce liquid methanol, which will be used as a biofuel source.

A recausticizing plant, which will be the largest in Europe (white liquor production of 16,000 m3/day), with two centrifuges for dregs, slaker-classifier, white liquor disc filter, and lime mud disc filter.

The new mill will be a next-generation bio-product pulp mill which can convert wood raw material into bio-materials and bio-energy in addition to high-quality pulp. It will not use any fossil-based fuels as all of the energy required will be generated from wood. The erection of the new mill is the largest investment in the Finnish forest industry ever.

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.
