Overcoming the "bark with a bite" at Valdivia

In January 2002, Celulosa Arauco y Constitución S.A. chose Andritz to supply a complete woodyard, black liquor evaporation plant, and white liquor plant for its Valdivia mill in Chile. One of the big challenges mas- tered by Andritz was the handling of eucalyptus and its unique bark.

"The biggest and the best environmental and energy equipment available today"

Requiring 22.5 months from breaking ground to start-up, UPM-Kymmene took a step into the future with its modernization and expansion at Pietarsaari. This is the world's largest single-line chemical recovery plant — and all Andritz technology. The recovery boiler has 600 MW biofuel firing capacity, with virtually no fossil carbon dioxide emissions.

Inside the Andritz recovery boiler — the world's largest at 4450 tds/d. The boiler operates at high pressure (92-102 bar) and high-tempera- ture (492-505°C). Steam generation with inter- nal circulation is 205 kg/s. A higher power-to- steam ratio increases power generation by 10%.

When NorskeCanada was formed, Antolovich was named TMP Operations Specialist. When presented with the challenge of increasing TMP tonnage and quality, he moved his team into the same building (they called it the "Pod") so they could interact and review progress on a daily basis. "We didn't have a real need to change before," Antolovich says, "because with the groundwood and kraft mills, TMP was putting out what it needed to. Also, with the closures, we lost our most experienced operators to retirement. This may have been a blessing. Experienced operators get into a comfort zone. They typically don't push the equipment to get the extra tonnage, for fear of plugging something or causing a breakdown. "But, that was then, and this is now.

A world’s first at Yueyang

China is the second largest producer of paper in the world. In order to satisfy domestic demand, it imports huge quantities of recycled paper and market pulp each year. Tiger Forest and Paper Group is a company that is developing its own sources of high quality fiber with the help of the world's first P-RC APMP pulping line and an Andritz woodyard.

Since the late 1980's, the company has been planting 500,000 Mu (33,000 ha) of trees for pulpwood. Species include slash pine, loblolly pine, and poplar.

At present, locally grown poplar is used for various end products including newsprint, LWC, and printing/writing grades. The poplar originally came from Italy and grows very rapidly. The region around Yueyang has good fertile soil, an annual rainfall of 1200-1400 mm, and strong sunshine. Winter lasts from November to March, but temperatures seldom fall below freezing. This results in a tree diameter of 20 cm at chest height within five years, when the first commercial cut can be carried out. Yueyang's woodyard includes an Andritz dry debarking-chipping line. Logs are fed through the debarking drum and then to the Andritz HQ- Chipper™. The chipper is gravity-fed and has a capacity of 105 m3 sub/h. According to the mill, it produces homo- geneous chips. The chips are screened with an Andritz CS-type screen and con- veyed to the storage silo, which uses a CenterScrew™ slewing screw reclaimer. "The Andritz woodyard equipment has run perfectly from the very begin- ning," Mr. Zhang Dong Ji says.

Breathing new life into Kingsport

Weyerhaeuser rebuilt its Kingsport mill essentially "from the ground up." A gleaming new continuous fiberline from Andritz started up in August 2003. This, and a new paper machine, make Kingsport a world benchmark for low cost free-sheet production. "It's as technologically advanced as any in the world," says the fiberline manager.

Kingsport is like a lot of small towns in America. Perhaps prettier than most, due to the surrounding Appalachian and Great Smoky Mountains. Also unique in another way — it has a large, yet virtually odor-free, pulp and paper mill near its town center. The mill, an important part of Kingsport's economy, was once owned by Mead, later Willamette, and, through acquisition, now Weyerhaeuser. Weyerhaeuser, one of the world's largest inte- grated forest products compa- nies, recently completed a major modernization that, according to all concerned, "rebuilt the mill from the ground up." A great deal of pride sur- rounds the "new" mill. The con- struction project logged 6.2 mil- lion work hours without a lost- "I have a lot of respect for the people who work time accident.

20 FiberSpectrum Issue 2 — 2004 The old batch mill

Not so long ago, things at Kingsport were not nearly as positive. The mill, operating since 1916, began to see hard times in the mid-1990's. Employees and the community knew that the mill might be closed any day. "If you go through the old pulp mill, you'll see six ancient batch digesters with manual capping valves," Chamberlin says. "There were panels where operators had to turn dials to manually adjust the speed of a washer. Before they replaced the recovery unit, Kingsport had one of the oldest operating Tomlinson recovery fur- naces (circa 1948) in the world."

A safe project, on budget, ahead of schedule

Over the years, Willamette earned a reputation as a builder of low-cost, effi- cient mills by managing projects with internal resources rather than outside engineers and construction firms. This capability transferred seamlessly to Weyerhaeuser. Design and engineering for Kingsport were provided by Weyerhaeuser Engin- eering Services (WES), with help from its construction management group. According to Howard Irwin, Area Con- struction Manager at the time, there were 1800 workers on site at the project's "An experience I'll value forever."

A lime kiln (relocated from anoth- er mill) and recausticizing equipment started n May 2003. And, the new Andritz bleached hardwood fiberline and rebuilt ClO2 plant, started up August 7, 2003 — two weeks ahead of schedule.

Sun Paper — The rising sun in China

Shandong Sun Paper is one of the largest privately-owned paper compa- nies in China. It has 17 paper machines at its mill in Yanzhou City, with a total capacity of one million tonnes per year. Its newest machine depends upon an Andritz stock preparation system, the first of its kind in China.

Shandong Sun Paper Industry started manufacturing paper 22 years ago with a single machine producing 1 t/d. It was a second-hand machine and the proprietor, Mr. Li, was not permitted to purchase new machine clothing. So he used off-cuts from the State-run mills. At the Sun Paper mill in Yanzhou City (two hours drive south of Jinan, the capital of Shandong province), total paper capac- ity is today over 1,000,000 t/a. According to Deputy General Manager and Chief Engineer, Mr. Ying Guang Dong, five machines (700,000 t/a capacity) make coated board grades. Three machines produce coated duplex board, with a top layer of 100% virgin fiber and the other layers from recycled fiber. The other two machines make folding boxboard. The rest of the mill produces printing and writing papers.The new PM19, started up in August 2004, has a capac- ity of 200,000 t/a. A new finishing line will be started up in August 2005. Andritz supplied the stock preparation system for PM19, the first complete Andritz stock prep line in China. This system features new Andritz Papillon™ cylindrical refiners, a thick stock screen- ing plant, and a complete machine approach system for maximum deaera- tion and final cleaning of the stock, as well as a CD profiling water system. "We installed the Andritz Papillon™ refiners in our new line at Yanzhou based upon our successful experience with them at the Guangdong Mill," says Mr. Ying Guang Dong. Sun Paper's mill near Yanzhou City produces over one million tonnes of paper and board products a year.
