• Best available ClO2 technologies for the pulp industry

  Japan TAPPI 2021 Abstract Eka Engineering is an engineering and contracting division within Nouryon Pulp and Performance Chemicals that specializes in the design and supply of chlorine dioxide (ClO2) plants and equipment to the pulp and chemical industries.

• Pulp Bleaching, ClO2 technology & related challenges

  In the highly competitive global Pulp and Paper industry the safe, reliable and efficient generation, storage and application of chlorine dioxide (ClO2) is one of several processes critical to sustainable management of bleached pulp production.

• Sustainable emotion: The Iggesund mill the “wow” factor

  Can anything really be new at an integrated pulp and paperboard mill, where the leading position in Europe has been held for more than 40 years? First, let’s take a look at the facts about this business.

• Improving chlorine dioxide bleaching efficiency, Tappi, VOL 7, Number 7 2008

  When operating chlorine dioxide (D) bleaching stages under mill conditions, it is important to establish reasonable operating targets and ranges. We examined the relationship between optimum pH, acceptable range for pH control, bleaching efficiency, and mill specific parameters such as wood species, pulp quality, and chemical charge.

• Environmental systems analysis of alternative bleaching sequences with focus on carbon footprint

  Substantial efforts have been made in order to improve the environmental impact caused by kraft pulp bleaching. The shift from chlorine bleaching to elemental chlorine-free (ECF) bleaching technology has resulted in significant improvements.
