Research and development
A passion for innovation
ANDRITZ PULP & PAPER’s continuous research and development activities focus on supporting customers to achieve sustainable production with higher capacities as well as higher energy efficiency and at the same time minimizing the consumption of energy, chemicals, and water. New technologies concentrate on the by-products of pulp production and on creating green energy.
R&D for biomass power boilers continues to focus on the combustion and emission behavior of different biomass feedstocks. The focus on developing low-effluent and chemical recovery systems for chemi-mechanical pulp mills continues.
To lower the environmental impact, ANDRITZ has been able to reduce the consumption of chemicals required for cooking and bleaching. Consumption of fresh water has also decreased.
Technology development in evaporation is focusing on producing highly efficient, low (or zero) effluent evaporation systems.
White liquor plant development is further reducing gaseous emissions and cleaning solid wastes to reduce toxicity.
Electricity generation in pulp mills is boosted with High Energy Recovery Boilers (HERB) that increase the amount of electricity generated from black liquor. Developments in mechanical pulping include new high-capacity and energy-efficient machines and systems.
For industrial grades of recycled fiber, development work is centered on the pulping process to reduce energy consumption. A compact partial deaeration system has been developed for inclusion within paper machine approach systems. One of the benefits of this development is lower power consumption.
ANDRITZ is developing technologies for ethanol production from non-food based raw materials such as wood and agricultural waste. Development of pressurized oxygen-blown gasifiers, which are used in liquid biofuel production, continues. A gasification process for biodiesel production is currently under development and the site selection process for the first production plant is ongoing.
The focus in service development is to continuously improve the efficiency of installed equipment and lower the operating costs. In support of this, sophisticated balance calculation tools, which model production costs, have been developed. Upgrade packages for specific equipment are being introduced to reduce energy consumption, maintenance costs and the consumption of consumables, and to increase reliability.
