Valmet-supplied world's largest production line for bleached softwood pulp successfully started up..  (Company news) SCA Östrand mill in Sweden

The expanded pulp mill SCA Östrand in Timrå, Sweden, was started up end of June 2018, according to plan. SCA invested SEK 7.8 billion in Östrand pulp mill expansion project making it one of the largest industrial investments in Sweden to date. With this project SCA Östrand doubled its production capacity from 430,000 tonnes to 900,000 tonnes per year and became the largest production line for bleached softwood kraft pulp in the world.

"The rebuild and expansion of Östrand pulp mill is one of the greatest industrial investments in northern Sweden ever. In spite of complexities such as building a twice as big pulp mill in a running mill, we started up the new plant on schedule and budget. The success is the work of many actors, not the least our supplier Valmet", says Ingela Ekebro, Project Director, SCA.

"The start-up went very well. Valmet delivered the most sustainable solution available today consisting of the new cooking, fiber line and evaporation plants," says Stefan Mattsson, Sales Director, Fiber Processing Business Unit, Valmet.

The project was implemented in phases, and the new evaporation plant was started up some months before the cooking and fiber line. Very soon after the start-up, pulp was produced with high strength, purity and brightness. In the next phase, the production is increased gradually towards the new nominal production capacity.

State-of-the-art technology and environmental performance
Valmet's delivery to the project included new cooking, fiber line and evaporation plant. The cooking plant has the world's largest soft wood digester, while the new evaporation plant is Sweden's largest with an evaporation capacity of 1,150 tons of water per hour.

The 7-effect evaporation plant is extremely energy-efficient, with its in-built possibility to also recover excess heat from Valmet's cooking plant and includes a methanol plant for producing liquid methanol. This enables Östrand to sell surplus energy in the form of green electricity.

Following the investment, SCA Östrand mill has state-of-the-art technology to minimize emissions to air and water. Customers will be offered both TCF (total chlorine free) and ECF (elemental chlorine free) pulp, produced with wood from sustainable forestry.

ANDRITZ supplied the following equipment for the SCA Östrand mill:
-a complete debarking plant with two parallel debarking and chipping lines each consisting of a PowerFeed de-icing conveyor, a hydrostatically supported debarking drum for a capacity of 425 m3 sob/h and measuring 5.5 x 39 meters, and a horizontally fed, XL-size HHQ-Chipper operating with a TK-IV knife system. The delivery also includes two new-generation HQ-Press bark presses resulting in excellent bark dry content, as well as modernization of the existing chip handling system;

-the new innovative EvoDry pulp drying system with its energy-saving technologies that substantially reduce the mill’s operating costs, including a boiler exhaust energy recovery system, fine screening, a twin wire dewatering system with a fully automatic tail threading system to meet strictest health, safety, and environmental regulations, a new-generation sheet dryer for lowest downtime and fast start up, as well as a cutter and two baling lines;

-new recausticizing machinery including a LimeGreen green liquor filter enabling efficient green liquor filtration with a minimum of waste going to landfill, two LimeFree centrifuges for dregs, LimeSlake technology, LimeWhite white liquor disc filter to optimize white liquor quality, and LimeDry lime mud disc filter upgrade;

-ANDRITZ LimeFlash technology, enabling a substantial increase in the capacity of the existing lime kiln without the need to invest in a new lime kiln. The delivery also included upgrade of the existing wood dust burning system, which ANDRITZ supplied in 2011 in order to support the new increased lime kiln capacity.

-substantial increase in the recovery boiler capacity from 3,300 to 5,000 tds/d. The existing boiler was supplied by ANDRITZ in 2006 and had already been designed to enable a major extension by moving the boiler side wall and widening the heating surfaces of the superheater, boiler generation bank, and economizers. The boiler extension by moving the side wall allows optimum flue gas flux before and after the rebuild, which has great benefits compared to traditional technology for expanding the recovery boiler by moving its front wall. The total increase of the boiler width was 3.8 meters. In addition to boiler enlargement, one additional ESP°(electrostatic precipitator) chamber and feed water pump were added.

The mill expansion was one of the largest industrial investments in Sweden and the largest ever in northern Sweden. SCA Östrand is doubling its annual production capacity from 430,000 to 900,000°tons, thereby becoming the largest mill in the world for softwood kraft pulp.

ABB: The digital mill  (Company news)

The only way to increase productivity is to work smarter – and that means working together, not separately. SCA’s Östrand pulp mill will be the first such mill in the world, for production of softwood kraft pulp, to use an automation system to control all of the processes in the entire mill.

Running a pulp mill is no simple enterprise. Several processes need to function on their own, but they also have to collaborate in a chain that should progress as faultlessly as possible.

“Roughly speaking, even though Östrand is a relatively modern pulp mill, we have several factories within the factory,” says Ingela Ekebro, project director for the Helios project at SCA.

“At the same time, the most competitive producer over time is the one that has the smoothest production that consistently operates at maximum capacity in all areas.”

This is the background to one of the largest investments in Swedish industrial history. SCA started reconstructing the pulp mill in Östrand in 2015, and the goal is for construction to be finished by June 2018. The project, which is called Helios, will cost a total of SEK 7.8 billion. Upon completion, production capacity will double, and the production line for bleached softwood kraft pulp will be the largest in the world.

However, being the largest is not necessarily the same as being the best – the different parts also have to work together.

“The technical level of our control is already good, but it has not been fully integrated,” says Alf Eriksson, who is the electrical and automation function manager in the project.

“We naturally purchase the best machines, but our competitors can do the same. Whether we only manage to do a good job or we are the best depends on how we run and optimize our plant.”
When planning the reconstruction, SCA decided to delay the individual parts and instead begin a procurement process for the automation system. ABB’s Ability System 800xA automation system was selected.

“This is a strategic issue. The control system is the cornerstone that affect how all parts of the factory works, which is why it was important for us to have all the different pieces in place as early as possible,” says Alf Eriksson.

However, it is not only the fully integrated automation that is new. The physical control room environment has also changed. The various processes are currently run from five different control rooms placed in different locations throughout the mill area, which is one square kilometer large.

“We have wanted to gather our personnel into one common operations center for several years,” says Anders Rönnqvist, project manager at the operations center at Östrand.

“Even if the current control rooms allow the operators to work close to operations, daily communication between the operators and with their immediate supervisor is not as close and instantaneous,” says Anders Rönnqvist.

As a result, SCA has decided to gather the control rooms for wood handling, fiber line and energy & chemical recovery into a common operations center that is centrally located in the mill area.

“Taking this step will lead to several positive effects,” says Ingela Ekebro.

“The operators will be closer to their supervisors and their colleagues, which will result in better communication and better opportunities to learn from one another. The daytime organization will also be gathered at the same place, which means communication with each other and with operations will be easier, and colleagues can help each other across department boundaries. This will in turn lead to increased understanding and knowledge of the different processes in the mill, which in the long run will lead to improved operations.”

The operations center will also be fitted with equipment from ABB.

“We liked how ABB was able to integrate the control system with the operators’ working environment,” says Anders Rönnqvist.

“It is the employees who are to perform a good job, and they have to be given the optimal conditions to do so.”

The control rooms will be fitted with ABB’s Extended Operator Workplaces (EOW), which are fully integrated operator solutions that provide both process overview and the possibility to adapt ergonomics and the work environment to the individual for everything from working posture to sound and lighting. To enable the greatest amount of operator support possible, SCA has also chosen to implement functions for advanced process control for all the process segments, integrated in the operator environment. This will provide operators with decision-making support in real time for optimal operation of the mill, at the same time as ongoing control and history are displayed.

“We are creating a modern, high tech workplace where focus is on productivity, technology and constant improvements, as well as a workplace that will continue to be appealing and attract the best possible operators in the future,” concludes Anders Rönnqvist.

SCA enhances its organization and invests  (Company news)

SCA is a global hygiene and forest products company with about 85% of its sales derived from its hygiene operations. To further intensify the focus on the Group’s two operations, SCA has decided initiate a dividing of the Group into two divisions: a Hygiene division and a Forest Products division. In relation to the Forest Products division, all forest industry and forest land currently owned by SCA will be merged into one division. A decision has also been made to invest in increased capacity for pulp production in the forest products operation.

“SCA is a global hygiene and forest products company in which we work continuously to enhance the respective operations. The enhancement of the organization and the investment in increased pulp production will secure the long-term competitiveness of the businesses,” says Magnus Groth (photo), President and CEO of SCA.

The Forest Products division will encompass all forest industry operations and all forest land currently owned by SCA. The work to realize this consolidation will now begin. There are significant synergies between the forest industry and the ownership of forest land. SCA’s forest products operation has a well-integrated supply chain with production facilities concentrated in Northern Sweden in close proximity to its forest holdings.

As of January 1, 2017, the Forest Products division will expand its quarterly financial reporting.

To satisfy the growing demand for pulp, SCA has decided to invest in increased capacity for pulp production at the Östrand pulp mill in Timrå, Sweden. The annual production capacity of bleached sulphate pulp will increase from the current level of approximately 430,000 tons to about 900,000 tons. The investment will amount to about SEK 7.8bn over a three-year period. Production is expected to commence in 2018.

“A cohesive forest products operation in a single division further highlights the value created and optimizes synergies between the forest industry and ownership of forest land. Over time, the investment in Östrand will increase sales and competitiveness and create a world-class cost position and higher margins,” says Magnus Groth, President and CEO of SCA.

New product launched by SCA  (Company news)

Picture: Johan Malker, Mikael Hjärpe, Jessica Sjöberg and Hans-Göran Nordin show the specially selected wood chips needed to manufacture Celeste Filter.

Celeste Filter is a new kraft pulp product recently launched by SCA Forest Products’ Östrand pulp mill. It is more porous than other Celeste products and is therefore well suited for production of products such as oil and air filters. Celeste filter will be delivered to producers of base paper for filters and in the next step of the value chain the filter paper is converted to end products, such as oil filters for cars.
“Celeste Filter was developed because we saw that there is a market and demand for this type of product. SCA Östrand will also provide customers with added value as a result of our strong environmental profile, service and quality,” says Johan Malker, Product Manager for Celeste.
In the initial phase, laboratory tests were carried out at SCA R&D Centre in Sundsvall.
“These were on a small scale so that we could define the conditions necessary to achieve the high degree of porosity. We discovered that wood chips from selected sawmills and the right process conditions yielded the desired qualities,” says Jessica Sjöberg, R&D engineer at SCA R&D Centre.

Good response from customers
Two large-scale test runs of Celeste Filter have been carried in the past year and the product has been distributed to a number of customers. Both trials have received good response, one of the customers in the filter segment tested the product and is very pleased with the results.
“In specialty segments, there are more meticulous requirements to produce the right quality at all times. Consistency is incredibly important and for customers it is crucial to receive the same quality each time,” explains Jessica.
