Motors are specified in green pulp
project
WEG is the preferred supplier of motors to the Veracel project due to the high levels of reliability, efficiency and robustness provided by its ranges of LV and MV motors.
WEG's LV and MV ranges of electric motors and control gear are providing the drive for all mill and associated facilities in what is probably the world's largest ecologically sustainable project to produce eucalyptus pulp Representing an investment, to-date, of US $1.25 billion, the Veracel project in Brazil is a joint venture between Aracruz Celulose, the world's largest producer of short fibre eucalyptus pulp, and Stora Enso, the second largest paper producer in the world

The pumps and motor sets are fitted with variable speed drives and can also vary the duty cycles, with one, two or three pumps working as required.
Motors chosen for blast furnace job
The 415V, three-phase AC motors range from 15 to 315kW and are being used on Weir Pumps in slag slurry, slag granulation, cooling circuit water and recirculation duties via vee belt drive trains.
The project comprises a nursery, sustainable plantations (147,000 hectares total area), a private forest reserve and a pulp mill, which produces 900kt of bleached eucalyptus pulp per year.
Located on the Brazilian state of Bahia, Veracel project is one of the world's most advanced mills, both in terms of the modernity of its processes and its environmental procedures.
The project employs eucalyptus trees because they offer several advantages compared with other forest species, including native trees.

Incorrect specification makes a mockery of manufacturers' efforts to improve motor efficiency, argues Andrew Glover.
Thanks to Brazil's favourable climate, and Aracruz's achievements in forestry research and technology, Veracel eucalyptus trees can be harvested in only seven years for pulp making - when they reach 35m in height.
As a result, the productivity of the company's eucalyptus forest is twice that of planted conifers, and for most of the country's native trees.
This is important as it means that the amount of land required for eucalyptus plantations is significantly reduced.
As supplier to Aracruz for electric equipment, WEG, itself an ISO14001 approved organisation, has been involved with the Veracel project since its inception, supplying both low and medium voltage electric motors for the control of a wide range of facilities including, fibreline digesters, causticising plant, line kilns, fibreline bleaching, fibreline brownstock, drying machines evaporation, water treatment plant and wastewater treatment plant.
WEG is the preferred supplier of motors to the Veracel project due to the high levels of reliability, efficiency and robustness provided by its ranges of LV and MV motors.
WEG motors are proven in some of the most operationally demanding environments in the world, including steel production, oil and gas, power generation, waste recycling, mining and quarrying and water treatment and desalinisation plants.
The motors are in keeping the ecological objectives of the Veracel project, providing high levels of efficiency to reduce energy use across all the mill activities.
