Ilim Group has signed a contract with ANDRITZ Oy to supply a recovery boiler for its new pulp and paperboard mill in Ust-Ilimsk.

Ilim Group has signed a contract with ANDRITZ Oy , affiliate of the Austrian based ANDRITZ Group, to supply a recovery boiler (RB) for its new pulp and paperboard mill in Ust-Ilimsk.

The recovery boiler is an essential part of the pulp and paper production process. The quality of its operation determines the environmental footprint of chemical recovery during the kraft pulping process. The new recovery boiler will be manufactured in line with global environmental standards and best available technologies (BAT) in regard of the environmental performance.

“Ilim Group is a leader in the Russian business community in terms of environmental costs. We are one of the top three companies in this rating,” said Kseniia Sosnina, Ilim Group CEO. “All of Ilim’s investment projects have a strong focus on implementation of best available technologies (BAT). In 2018, Ilim invested more than RUB 11 billion in BAT projects, and this year we will maintain the same level of our environmental investments. Reduction of the environmental footprint is a key priority for us, that is why we select our suppliers very carefully. Andritz is not only a manufacturer of high-quality equipment, but also a technology pioneer. We are confident that our joint projects will be implemented successfully.”

“We are very proud to support Ilim Group in reaching their environmental goals with our globally proven technologies. This order again demonstrates the excellent relationship with Ilim Group”, says Kari Tuominen, President of ANDRITZ Oy.

To reduce emissions, Ilim’s new recovery boiler (RB) will be equipped with a highly efficient double-chamber precipitator, which will remove the dust and ensure that its concentration in emissions does not exceed 50 mg/Nm3. Additional incineration systems, including a stand-by incinerator, will be installed to ensure incineration of concentrated gases. Boosted equipment capacity will allow to increase the amount of black liquor dry solids fed to the incineration systems, bringing it to at least 75% ds, which will improve the boiler efficiency and at the same time significantly reduce the environmental footprint.

Moreover, the RB will be equipped with a distributed process control system (including automated control of incineration process) and online control of technological processes, which will ensure enhanced reliability and safety of the manufacturing process. The equipment will have a heat-power recycling system, which will allow to save resources and contribute to the reduction of the environmental footprint. The capacity of the new RB will be 1,950 tpd dry solids. The RB start-up is scheduled for 2021.

In the beginning of 2019, Ilim Group signed another large contract with the ANDRITZ Group to supply equipment for a new woodroom at the Koryazhma Mill. The new woodroom will have two debarking and chipping lines, chip and bark handling equipment as well as a SmartWoodyard advanced control system. The cutting-edge production process will reduce wood losses, and water and electric energy consumption per unit of product. The start-up of a new woodroom is scheduled for November 2021.
