ANDRITZ receives major order from Mondi Syktyvkar, Russia

International Technology Group ANDRITZ received an order from Mondi Syktyvkar Pulp and Paper mill in Komi Republic, Russia, to supply a new recovery boiler, evaporation plant, and woodyard.  The order also includes the rebuild of the existing fiberline.  The typical order value for such a project is 100-130 MEUR; order completion is scheduled for 2010.

Recovery boiler

The state-of-the-art 3,560 tds/d recovery boiler - equipped with odorous gas incineration systems - maximizes electrical energy generation in the plant, thus ensuring cost-effective power generation in the mill and helping to protect the environment.

Evaporation plant

The supply also includes an evaporation plant and a condensate stripping plant. Six-effect evaporation plant with crystallization technology used in the concentrators has a water evaporation capacity of 550 t/h; the final product solids content is about 75%. All condensates are separated for further use within the pulp mill. The condensate stripping plant purifies the methanol-rich condensates from the new and the existing evaporators. The collected methanol is treated in a new methanol plant to produce liquid methanol fuel.


The woodyard, which has a capacity equivalent to a pulp production of 875,000 t/y, consists of two debarking lines with the highest capacity in the world. Rated capacity for SW is 415 m3 sob/h and for HW 300 m3 sob/h per line. Each line consists of a PowerFeed infeed conveyor, steel-wheel supported debarking drum (5.5 x 42 m), efficient washing and bark separation section, and a horizontal-feed HHQ-Chipper. The chippers, HHQ-EXL, are the biggest in the world, with 3.87 m disc diameter and 18 knives. The chipper is designed to produce homogenous, high chip quality with extremely high capacity of the lines. The rated capacity of the chipper is up to 800 solid-m3/h, depending on the average diameter of the wood logs. The debarking plant also includes bark shredding with two bark shredders, bark pressing, and complete water treatment.

Rebuilding of the existing fiberline

The fiberline delivery includes an upgrade of hard- and softwood lines.  The hardwood fiberline comprises a brownstock washing upgrade with a pressure diffuser and two-stage DD washer. Furthermore, the supply includes a bleaching upgrade with new A and D stages containing a new DD washer; the capacity will increase to 1,500 t/d The new A stage will be the first one in Russia. For the softwood fiberline, ANDRITZ will convert the existing continuous digester to Downflow Lo-Solids cooking. The upgrade also comprises a TurboFeed chip feeding system; the capacity will increase to 1,000 t/d.
