The balance between technological advances and return on investment is precarious and before major capital is spent on new projects, careful study is done on the potential turn-around time of new installations and rebuilds. In these economic times, projects around the world go through rigorous review before being given the green light. In Canada, only a few projects have matched the scale of some of these international committments. What standards were set around the world by recent projects to justify investment and how do the projects here compare?

Besides speed, which translates into greater quantities produced, some of the recent projects undertaken by Voith Paper and Metso Paper, among the two best known paper machine builders, have included record-breaking statistics and higher quality production, as well as the incorporation of environmentally conscious methods. A partial list of recent orders from both companies follows.

Around the world records

At 1,567 m/min, Soporcel, Portugal, set a new world record in July, 2003, producing fine paper on PM2. The paper machine for uncoated, wood-free fine paper was delivered by Voith Paper and started up in July 2000. The last record, at 1,514 m/min, was reached on this machine one year ago. Starting on July 6, 2003, the machine produced 3,800 t fine paper in a basis-weight range of 70-80 g/m2 at a speed of 1,567 m/min for more than 75 hours. The operating time efficiency was 90.3%.

Almost at the same level is the coated and uncoated wood-free fine paper produced by the Metso’s PM8 at Kuusankoski, Finland, which is running at 1541 m/min with a basis weight of 50 to 130 g/m2. Other Metso world records include Stora Enso’s Port Hawkesbury PM2 for SC paper which is running at 1800 m/min; Norske Skog’s Golbey newsprint machine in France, running at 1902 m/min and the PM4 for LWC at Rauma, Finland, running at 1853 m/min.

Depressed economy causing anticipated undershoot

Although the times are still hard and overall order values are down, the above projects show that there are still bright spots.

Voith Paper and Voith Fabrics — the two divisions of Voith Paper Technology — received combined new orders in fiscal 01/02 worth a total of _1.5 billion despite poor market conditions. Although this marked a decline of 13.9% from the previous year, the figure for 02/03 is expected to be higher.

Metso’s Annual Report for 2002 stated that Metso Paper’s net sales were _1.812 billion. The Interim Review (Jan 1 – June 30, 2003) admitted that customers were a little more reluctant to commit to larger projects, but went on to say that, on the whole, the market for Metso’s products was satisfactory. New orders were focused on rebuilds of papermaking and pulping lines and on finishing systems.

Future possibilities

Along with the difficult economic times, investment in general has slowed down but mills continue to need investment in capital equipment as a basic necessity for maintaining productivity and competitiveness.

According to Voith, there is a demand for machine rebuilds to convert to value-added grades (e.g. coated paper). These rebuilds involve new headboxes for better sheet uniformity and better basis weight profiles, top former rebuilds for better formation, shoe presses for higher sheet dryness before the dryer section (i.e. less steam consumption or PM speed increase), dryer section rebuilds for better sheet support/stability, on-line coaters to convert to value-added grades, on-line supercalenders to produce smoother and glossier paper (i.e. value-added grades), new reels to enable reeling of good quality parent rolls from very smooth paper.

As the economy improves, the outlook for more orders should increase.#text2#
