Valmet's iRoll product family is a complete set of tools for controlling paper tension and nip profiles. iRolls are now available for all main processes and positions in pulp, paper, board and tissue machines with the latest Valmet roll covers.

Thanks to good market feedback, Valmet is now expanding its iRoll manufacturing capability. By the end of June 2014, iRoll manufacturing will expand to cover Finland, France, the United States, Thailand and China. Valmet has also developed local field service competencies through an iRoll academy training program.

"After installing an iRoll, our customers have thanked us for 50% fewer wet end breaks per day, improved runnability, 100% longer grinding intervals and a 40% improvement in the coat weight 2-sigma value, just to name a few of the results iRoll has achieved," says Samppa Ahmaniemi, director of Roll Covers at Valmet.

Accurate online measurements

The main benefit of the iRoll technology is its accurate online profile measurement and process control opportunity in press, sizer, coater, reel and winder applications. Valmet's iRoll is the fastest and most sensitive online profile measurement tool in the industry.

In addition to nip load profile, iRoll also measures applicator rod load profile (sizer) and parent roll hardness profile (reel), as well as paper, board or tissue tension profiles in selected positions. iRoll can even be connected to the machine automation system for closed loop process control.

iRoll Portable is a quick, cost-effective process analysis and tuning tool that is based on dynamic nip profile or paper/fabric tension profile measurements. iRoll Portable provides rapid results as Valmet's experts can carry out an iRoll Portable analysis during shutdowns.

Valmet has received a major rebuild and new equipment order from Södra Cell for the Värö pulp mill in Sweden. The order is part of Södra Cell's over 400 million euro investment to increase the Värö mill's pulp production capacity from 425,000 tons to 700,000 tons per year. 

The order is included in Valmet's second quarter 2014 orders received and is valued at around EUR 200 million. 

Valmet's delivery will contribute to Södra's performance by significantly increasing the Värö mill's pulp production capacity and energy efficiency. The order consists of a new continuous cooking plant and upgrades of wood handling, fiber line, evaporation plant, recovery boiler, recausticizing, flash dryer, pulp dryer and baling. On completion of the project, Värö will be one of the world's largest softwood sulphate pulp mills. The start-up of the renewed pulp mill is scheduled in the third quarter of 2016.

 "We have good experiences of Valmet and feel confident that this project will be a success. We have worked closely together with Valmet in planning the project and it gives us a good start. This investment increases our pulp production, makes the mill more energy efficient and increases its bioenergy supply potential", says Gunilla Saltin, CEO, Södra Cell.

"We are very pleased that Södra Cell trusted us with this significant order. It is a strong token of our technological leadership and competitiveness in the pulp technology market. Investments in pulp production are active at the moment and Valmet is strongly involved with many major on-going projects", says Jyrki Holmala, President, Pulp and Energy Business Line, Valmet.

Significant employment impact

The estimated employment impact of the order is about 650 man years mainly in Sweden. A large part of the order will be delivered from Valmet's operations in Sweden: the cooking plant and recausticizing from Karlstad, fiber line, flash dryer and baling from Sundsvall, and evaporation and recovery boiler from Gothenburg. The wood handling and pulp dryer delivery will come from Finland. 

A prerequisite for construction start is the receipt of a permit from the Environmental Court of Appeal.

Södra has appointed Valmet of Finland as its main supplier for process equipment for the expansion of the pulp mill in Värö, near Varberg. This order is part of Södra's investment totalling more than SEK 4 billion.

The order placed with Valmet includes a new continuous digester and upgrades to wood handling, the fibre line, evaporation plant, soda recovery boiler, causticisation, flashdryer, drying machine and baling.

A large portion of the order will be supplied by Valmet in Sweden: The digester and causticisation will be supplied by Karlstad, the fibre line, flashdryer and baling by Sundsvall, and evaporation and the soda recovery boiler by Gothenburg. The wood handling and pulp dryer will be supplied by Finland. Valmet states that the order from Södra is worth around SEK 2 billion.

"We have good experiences of Valmet and feel confident that this project will be a success. We have worked closely together with Valmet in planning the project and it gives us a good start. This investment increases our pulp production, makes the mill more energy efficient and increases its bioenergy supply potential", says Gunilla Saltin, President, Södra Cell.

Investments in pulp production are active at the moment and Valmet is strongly involved with many major on-going projects", says Jyrki Holmala, President, Pulp and Energy Business Line, Valmet.

Södra has previously purchased groundwork, building work and construction work from NCC with regard to the expansion of Värö. Another major supplier is Raumaster, which will be supplying storage and transport equipment for chips and bark.

When the expansion work is complete, Värö will be one of the biggest pine sulphate pulp mills in the world, with a total production capacity of 700,000 tonnes of pulp per year. These investments will also considerably increase Värö's energy efficiency.

Valmet Corporation is a global developer and supplier of services and technology for the pulp, paper and energy industry. Valmet has revenues of around EUR 2.6 billion (2013) and employs 11,000 staff, and its head office is based in Espoo, Finland.

Valmet will supply a part of a major rebuild and some new equipment to a pulp mill of Siam Cellulose Co., Ltd. (SCL) in Thailand. The mill is located in Wangsala, Kanchanaburi province. The value of the order is around EUR 30 million. The order is included in Valmet's second quarter 2014 orders received.

The order includes an upgrade of the cooking plant and a fiber line rebuild. The new equipment delivery includes an evaporation plant, a recovery boiler, an ash leaching plant and a non-condensable gas treatment (CNCG) collection and burning system. The rebuilt plant is planned to be in operation in the beginning of 2016.

"We chose Valmet based on our earlier successful experience with the Phoenix Mill's recovery boiler performance and CompactCooking G2 technology," says Surasak Amawat, Managing Director of Siam Cellulose Co., Ltd.

"This order continues our successful cooperation with Siam Cellulose, and proves our commitment to move our customers' performance forward with fit-for-purpose and value-adding solutions", says Anil W. Purankar, Vice President, Pulp and Energy Business Line, Asia Pacific, Valmet.

Details about the order

The existing cooking plant will be converted to Compact Cooking G2 by adding an ImpBin^TM impregnation system, a decision based on the successful experience of improved pulp quality in Phoenix mill. The rebuild of the fiber line includes installation of Delta screens, wash presses, screw conveyors and medium consistency pumps.

The new evaporation plant will replace the existing plant and support the need for increased pulp production. The new RECOX recovery boiler is a repeat order from SCG Paper and will replace the existing boiler and increase the pulp production capacity. The new ash leaching system will help the mill to maintain low levels of potassium (K) and chloride (Cl).
