Valmet to supply evaporation and white liquor plant for Star project in Brazil


T


he pulp production line at Bracell’s Star project in Brazil (see also p29) will be built by Valmet.


Equipment to be suppled for the


project at Lençóis Paulista includes an evaporation plant and a white liquor plant, in which the lime kilns are fueled with gasified biomass. It will contribute to the mill’s capacity being increased from 1.25 million tonnes to 1.5m tonnes a year. “The new São Paulo unit in


Lençóis Paulista will feature best- in-class technology with a flexible line designed primarily to produce dissolving pulp. This project is the largest private investment in the São Paulo state in the last 20 years and it generates employment


opportunities for the entire region,” said Bracell’s projects director Carlos Pastrana. Bertel Karlstedt, president of the pulp and energy business line at Valmet, added: “Our technology represents new innovations and is designed for flexible production with high energy efficiency. The project will have a significant employment impact both for engineering and production in Brazil and the Nordics.” The equipment being supplied


by Valmet includes an evaporation plant with a super concentrator. The plant features Tubel technology for highest availability and easy washing. The evaporation is designed for high energy efficiency with energy recovery


New tissue production line for Alas Doradas in El Salvador


An Advantage DCT100HS tissue production line, including a de- inking plant and an extensive automation package, is being supply by Valmet to Alas Doradas in El Salvador. The new tissue line will meet


a need at Alas Doradas for new capacity of high-quality tissue products in the region. The start-up is planned for the first half of 2021. Chief executive of Alas Doradas


Paul Ekman commented: “Our cooperation with Valmet started with the rebuild of our existing machine where the press section was upgraded with an Advantage ViscoNip press combined with Advantage ReDry technology.


January/February 2020 “With the results achieved,


we are convinced that Valmet’s technology is what we need to differentiate from competition and become the frontrunner in the Central American tissue market. Even more important is the collaboration with a reliable partner as Valmet. We see this as the first step in a long-term partnership. Valmet has met and exceeded all expectations as a reliable partner during our cooperation.”


The machine will have a width of 2.8 metres and a design speed of 2,000 metres/minute. It will add 35,000 tons tissue paper per year to Alas Doradas’ current


from hot weak black liquor. The white liquor plant is an


essential part in the mill’s chemical recovery process. This includes the complete white liquor plant with recausticizing and two lime kilns. In addition, Valmet will provide two biomass dryers and gasifiers. The two lime kilns are fueled with biogas, thereby decreasing the need for fossil fuels. The white liquor plant is designed for producing high quality white liquor for cooking with lower operating cost with renewable furnace fuels and low specific heat consumption. A non-condensable gas handling


system will control and minimise odours emerging from the chemical recovery processes. Commenting on the energy


system, Fernando Scucuglia, director of Valmet’s pulp & energy division in South America, said: “Valmet has extensive experience in delivering fossil-fuel-free lime kilns, which are fueled with either wood powder or gasified biomass. Using gasified biomass is a sustainable and economical solution for large mills. Our solution works seamlessly together throughout the whole process from biomass drying, gasification and lime kiln to emission control. Our evaporation technology represents leading energy efficiency and is designed for long lifetime and high availability.” More information from Bertel

The Valmet and Alas Doradas teams celebrate the signing


production of high-quality toilet tissue, napkins and kitchen towels. The production line will include


a complete deinking plant and an Advantage DCT 100HS tissue machine. The machine will be equipped with OptiFlo headbox and cast iron Yankee cylinder as well as the Advantage technology


including ViscoNip press, AirCap hood, WetDust dust system and SoftReel reel. Also included will be an extensive automation package with Valmet DNA, Valmet IQ quality controls, Industrial Internet applications, Valmet Performance Center agreement and tissue line training simulator.
