Solvay to build integrated hydrogen peroxide unit at pulp mill site in Brazil

Solvay SA  and its affiliate Peroxidos do Brasil have agreed with Suzano Papel e Celulose to build a small dedicated hydrogen peroxide production unit using Solvay’s myH2O2 technology, at Suzano’s pulp mill site in Imperatriz, Maranhão, Brazil.

This is the first agreement that Solvay has signed for its myH2O2 peroxide technology, developed for installation at remote customer premises. This unit will use Suzano’s hydrogen feedstock, utilities and site services and supply all of the site’s hydrogen peroxide needs for pulp bleaching. It will be controlled from Solvay’s peroxides plant in Curitiba, about 2,700 km south of Imperatriz.

“We believe that this technology will help us to be more competitive and efficient, as it will allow us to reduce costs in the purchase of an important input that we bought from another state. The forecast volume includes our increased capacity, which will be implemented in 2017,” says Walter Schalka, CEO of Suzano Papel e Celulose.

myH2O2 units, with production capacities ranging from 5,000 to 20,000 metric tons per year (m.t./yr), have a low environmental footprint as they limit H2O2 truck supplies and re-use the hydrogen already available from other production processes on the customer’s site.

“Solvay’s first myH2O2 agreement shows the unmatched scope of our hydrogen peroxide technology capabilities, ranging from building and operating these small satellite units to mega units with a capacity exceeding 300 kilotons per year,” said Georges Crauser, President of Solvay’s Peroxides Global Business Unit. “The unique and flexible myH2O2® units save logistics needs, re-use resources that are readily available on-site and thereby substantially benefit the environment.”

Solvay is discussing several opportunities for its satellite myH2O2 plants with customers at remote locations worldwide.

Peróxidos do Brasil is a joint venture between Solvay and Produtos Quimicos Makay.
