CleanFlow AB (Forshaga, Sweden) has signed an agreement for the delivery of a new green liquor filtration system to a leading pulp mill in Spain. The factory in Pontevedra belongs to the forest industry group ENCE Energia Y Cellulose S.A. and produces more than 450,000 metric tons of eucalyptus pulp per year.

With the patented CleanFlow technology, this means that the green liquor in the pulping process becomes particle free and the amount of contaminants in the process is significantly reduced. This improves operation in the factory and increases production capacity at the same time as both environmental and energy savings are achieved. 

The capacity of the new CleanFlow system has been dimensioned to fit the mill’s ongoing production capacity increase. Thanks to building the CleanFlow system in modules it can be easily expanded and thus adapted also to future capacity increases.

The plant is designed, manufactured and completed with instrumentation and drive equipment in spring 2019. Testing is done at the CleanFlow facility in Forshaga, before delivery for tie-in and commissioning in the factoryduring the summer.

"We are very pleased that CleanFlow’s solutions for high-quality pulp production continue to be implemented around the world. This project represents another major step for CleanFlow."Lennart Källén, VD CleanFlow AB.
