TAILIEUCHUNG - Applications Mechanical Seals -Sealing Technology in Pulp and Paper Production

Gaseous injection of sulfur dioxide was beginning in 1993 and is a part of the quick-germ (QG) and quick-fiber (QF) techniques currently being devel- oped. There is revived interest in the use of special corn hybrids high in starch, though their use is still not widespread. Membrane filtration and yeast immobilization were being used in some plants in 1993, but their use, contrary to expectations, has not increased. Bacterial fermentation is still not used commercially, nor is cellulosic conversion of corn fiber. There have been no outstanding developments in coproducts, but the potential remains for their future exploitation. Most of the cost savings have been through plant automation and. | EagleBurgmann. Your partner for sealing technology worldwide Applications Mechanical Seals 50 E Sealing Technology in Pulp and Paper Production. EagleBurgmann - Your partner for sealing technology in the pulp and paper industry Worldwide demand for paper and paperboard in 2005 was about 360 million tons and is likely to grow to about 500 million tons by 2020. The pulp and paper industry therefore continues to be a definite growth sector. If anything developments such as the paperless office or new media have actually contributed to an acceleration in the consumption of paper. With paper consumption continuing to rise it is becoming extremely important to strike a harmony between economy and the protection of the environment. This implies a careful use of wood as a regenerative material controlled consumption of water and energy and particularly the recycling of waste paper as a raw material . Modern sealing technology makes a major contribution to optimized production processes and their further development. The paper industry today The processes needed to produce pulp and paper are highly energy-intensive. If only for reasons of economy companies are concerned therefore to minimize the specific consumption of their mostly self-generated supplies of steam and electricity through continuous rationalization and modernization. Circulating systems are used for example to reduce the fresh water content of the vast quantities of water required in pulp and paper production. This in turn cuts the amount of waste water that is subjected to mechanical and biological treatment usually in the companies own sewage treatment plants. And where the chemicals used in pulp production are concerned the biggest part is now recovered and recycled. Environmental protection With its collection and recycling of old paper the paper industry is making a major contribution to easing the pressure on our environment. In hardly any other sector has the recycling of raw materials attained such .
