Evaporation System Modernization at OJSC "Ilim Group" Branch in Koryazhma, Russian Federation

OJSC "Ilim Group" Branch in Koryazhma (official site of the company www.ilimgroup.com)

The project is implemented on the site of OJSC "Ilim Group" Branch in Koryazhma (the former OJSC "Kotlas Pulp and Paper Mill"), one of the largest wood chemical plants in Europe.

This project envisages construction of a new high-technology evaporator plant manufactured by "Andritz" with the evaporating capacity of 600 tonnes per hour, and decommissioning of the two old evaporator plants. The new evaporator plant was put into operation in 2007.

The project implementation made it possible to reduce steam consumption for liquor evaporation and fresh water heating (due to re-use of warm water and condensate streams from the new evaporator plant for the Mill’s process needs), and to increase energy generation at the Mill’s technological heat and power station due to combustion of more liquor and due to set up of combustion of methanol fraction and malodorous gases in a dedicated utilizing boiler.

The greenhouse gas emission reduction as a result of the project implementation is achieved through reduction of natural gas combustion at the Mill’s technological heat and power plant. The project implementation also allowed to decrease emissions of pollutants and malodorous gases, reduce discharge of polluted effluents into the Vychegda River, which has a positive impact upon the environment and public health in the region.

Expected emission reductions over 2008-2012 – 880 kt ÑÎ₂e
