Veolia’s HPD black liquor evaporator system chosen by Chung Hwa Pulp
Chung Hwa Pulp has selected Veolia Water Technologies’ HPD® evaporator technology to upgrade its Hualien Mill in Taiwan. This upgrade requires raising the capacity and Heavy Black Liquor concentration of the black liquor evaporator trains, in order to meet the future production of fiber line.
The main design requirements from the client were the optimization of the steam consumption, while making sure not to overload the existing equipment and with minimal interaction with the existing plants.
Of the two evaporation trains (#3 and #4), only train #3 was modified, adding the seventh and eight effect, a parallel second effect and a back-up condenser. The output of both trains is concentrated at a new concentrator, integrated on train #3.
The project will involve an additional 80 t/h H2O evaporation and a solids increase from approximately 66% up to 75%.
“The optimized OPEX offered by Veolia’s solution to Chung Hwa Pulp was ultimately the difference maker in this project, consolidating Veolia’s positioning as an important partner in the Pulp & Paper industry” commented Klaus Andersen, CEO Veolia Water Technologies Americas.
Chung Hwa Pulp Corporation produces, sells, and trades in pulp and paper products primarily in Taiwan and mainland China. The company operates in two segments, Pulp and Fine Paper, and Forestry.
