RESEARCH AND DEVELOPMENT<br />
Research and Development (R&D) is one of the<br />
Group’s important strategic goals. In <strong>2004</strong>, Andritz<br />
invested approximately 21.1 MEUR in the development<br />
of existing and new products and processes.<br />
Approximately 180 people work in the Group’s<br />
research centers in the USA, Austria, Finland, and<br />
France to develop new processes and equipment<br />
and expand Andritz’s technological leadership.<br />
The Divisions of the Pulp and Paper Business<br />
Area focus their R&D programs primarily on<br />
improving fiber quality, increasing energy efficiency,<br />
lowering the investment cost per ton of product<br />
manufactured, lowering maintenance costs, and<br />
reducing the environmental impact.<br />
Some newly developed products of the<br />
Pulp and Paper Divisions include:<br />
Wood Processing: Chip Sampler/Analyzer and<br />
RotaBarker for frozen wood and tropical<br />
hardwoods<br />
Fiberline: ModuScreen A for combined coarse<br />
and fine screening of pulp<br />
Recovery: High Energy Recovery Boilers (HERB)<br />
which considerably increase electrical generation<br />
capacity<br />
Chemical Systems: LMD-Filter for lime mud<br />
dewatering<br />
Mechanical Pulping: optimization of the<br />
Preconditioning-Refiner Chemical (P-RC)<br />
Alkaline Peroxide Mechanical Pulping (APMP)<br />
process for alternative raw materials; Bleach<br />
Commander process control system<br />
Pulp Drying: world’s largest single-line systems;<br />
slab press for flash drying<br />
Fiber Preparation: LC/HC pulpers with reduced<br />
energy consumption; ShortFlow paper<br />
machine approach; RotoWash for ash washing<br />
and fiber recovery<br />
Tissue: Machine Direction (MD) flexibility<br />
for TissueFlex shoe press; PrimeReel<br />
Centerwind for crease-free winding at very low<br />
STATUS REPORT<br />
nip loads to secure highest softness and volume<br />
of tissue paper; PrimeRun for utmost<br />
sheet stability in the dry end; enter the TAD<br />
technology and start up of first TAD machine<br />
Services: Bar-Tec wedgewire screen baskets;<br />
conical refiner plates; digester screen plates;<br />
diagnostics and condition monitoring systems;<br />
screw press shaft machining device<br />
The trend today is toward large, single-line<br />
mills since redundant or repetitive smaller systems<br />
increase both capital and operating costs.<br />
This places extreme demands on the equipment<br />
in terms of scale, reliability, and availability. All<br />
Andritz Divisions are actively developing larger<br />
scale equipment. UPM-Kymmene’s Pietarsaari<br />
mill demonstrates Andritz’s capabilities in engineering<br />
and producing one of the world’s largest and<br />
most efficient chemical recovery systems. Recent<br />
orders from Veracel in Brazil, Hainan in China, and<br />
CMPC in Chile will showcase large-scale Andritz<br />
fiberline and pulp drying systems. The chemimechanical<br />
pulp mill being built in Kunda, Estonia,<br />
will have a large twin wire pulp dewatering press,<br />
and the installation at UPM’s Shotton (UK) showcases<br />
a nearly 1,000 t/d large single-line screw<br />
press and disperser from Andritz for recycled fiber<br />
processes.<br />
The patented TurboFeed system is now generally<br />
accepted to be the most advanced, but<br />
also the simplest and most reliable solution for<br />
chip feeding to a continuous digester. It has been<br />
included on the most recent orders Andritz has<br />
received for continuous cooking systems, including<br />
very large (3,000 t/d) digesters.<br />
In the pulp bleaching area, chemical consumption<br />
has been decreased to record low levels with<br />
Andritz technology. The key elements to achieving<br />
this are the fractional washing capabilities of the<br />
DD Washer and selective removal of hexenuronic<br />
acids (A-Stage Bleaching).<br />
Andritz has done considerable development<br />
work to minimize emissions from the recovery<br />
boiler (particularly NOx) and to improve the reliability<br />
and safety of the boiler while maximizing energy<br />
production of the boiler at the same time.<br />
