JOURNAL FREE ACCESSThe technique to take the real-time data of wet paper web moisture and the two parameters-“Heat Transfer Rate Coefficient” and “Pressing Coefficient”-which related to the moisture makes it possible paper machine to be controlled reliably and precisely, and improves the productivity.
Additionally, the accumulation of time-series files which contains simultaneously moisture data at different parts of paper machine, above-mentioned parameters and general operation data leads to systemize quantitatively the reason for moisture variations. This systemization standardizes the control action which traditionally based on experiences or subjective factors, and rationalizes significantly paper machine operation.
“Heat Transfer Rate Coefficient” and “Pressing Coefficient” are the specific factors in “MOAS”;“HTRC” is the specific characteristics of paper which resulted from furnish composition and wire retention, affecting hydrokinetically to dewatering performance at press section.“PC” reflects quantitatively the dewatering performance at each press section.View full abstractDownload PDF (1610K) -

JOURNAL FREE ACCESSThis article illustrates the possibility of contribution to the measure against global warming by Japanese Pulp and Paper industry and overseas forest plantation. While the vast majority of pulp wood used in paper making originates from saw mill residues and thinning, the industry has made a commitment to expand overseas forest plantations in order to secure wood supplies and to contribute to the world's environment.
Japanese Pulp and Paper companies together plan to establish 550, 000ha of forest plantations, both inside and outside Japan by year 2010. As for Oji Paper Co. Ltd. it has a goal to establish 200, 000 ha of overseas forest plantations by 2010. Overseas forest plantation projects not only create jobs, but help the area in environmental improvements such as reduced salinity and reduced wind erosions. In addition, cultural exchanges between Japanese expatriates and locals take place. Recently, carbon absorption by forests is drawing more attention toward forest plantations. While it is not clear how carbon absorption is accounted and valued, Oji plans to help other companies which plan to develop overseas forest plantation projects. Overall. forest plantations mean recycling of wood, reducing the use of fossil energy while lessening the pressure to clear natural forests.View full abstractDownload PDF (1941K) -

JOURNAL FREE ACCESSNippon Paper Industries has been developing the clonal propagation technology of E. globulus by micropropagation to supply a high yield, quality, survival rate and uniformity for plantation purposes. In 2000, our research laboratory was established in Collie. Western Australia in order to try to produce clonal plantlets by micropropagation. A photoautrophic culture in the rooting stage produced more than ten thousand vigorous rooted-plantlets and enabled us to work the culture under non-aseptic conditions.
A low temperature plant tissue storage method propagated enough shoots to provide for rooting with a regular amount of work in the shoot propagating stage. These methods technically and economically improved micropropagtion of E. globules for practical use. The micropropagated plantlets were planted in plantations in Victoria and Western Australia. They have shown healthy growth without any problems for the initial period.View full abstractDownload PDF (4633K) -

JOURNAL FREE ACCESSReuse of the oxygen in the exhaust gas from ozone bleaching process is an available technology for chemical saving. To use the residual oxygen effectively, it is necessary to destruct the residual ozone, and to refine oxygen. In this paper, we will introduce the newly developed exhaust gas treatment system for ozone bleaching process.
This system is composed of a packed type absorbing tower, pumps and fans. And for absorbing agent we use alkali in the kraft pulping process, which contains sodium sulfide for ozone destruction and caustic soda for carbon dioxide absorption. This system is very simple, and almost free from corrosion, and the maintenance is easy. And also as an ozone destructor, both equipment cost and running cost are cheaper compared with the heating type one. These points are also discussed in this paper.View full abstractDownload PDF (2335K) -

JOURNAL FREE ACCESSA new electrolytic process to produce highly concentrated polysulfide (PS) liquor from white liquor has been developed. This electrolytic process can provide two different compositions of cooking liquor. not only electrolytic oxidized liquor (EOL) but also caustic soda, from the white liquor (WL) in the process. By adding the EOL to the digester, a great improvement of pulp yields can be obtained and required active alkaline can be reduced. In addition, combined use of the electrolytic cell and modified cooking (MC) enhances both effects of EOL. But a mill scale has not been realized yet because of high capital investment and large electricity for electrolytic process.
To optimize the combinatorial use of EOL and MC economically, optimum balance of PS and sodium sulfide in PS cooking liquor are discussed in this paper. Consequently the amount of WL to be oxidized with electrolyzer was reduced. Also a new electrolyzer was tested in long term. Successful results of the operations with pilot-scale are shown in this paper. This new electrolyzer is expected simple enough to install in practical mill scale.
Through the optimization of the way of cooking, it was found that whole WL does not have to be oxidized with electrolyzer. As a result of the development of new, simple and compact electrolyzer with high efficiency, required electricity was economized and space for installation was reduced and acceptable capital investments can be achieved.View full abstractDownload PDF (4663K) -

JOURNAL FREE ACCESSIn relation to the recent rapid development of web-offset printing, fluting in web-offset printing is becoming a serious quality issue requiring an urgent solution. Our study on this issue identified that fluting in web-offset printing is a phenomenon where an imaged area had been buckled by a compressive force caused by a combination of tension and contractile force during the printing operation. Also, the number of the fluting in web-offset printing is determined by the compressive force, the size of the imaged area and the stiffness of the paper.
On Dec. 2001, we started to produce a new paper product which is free from the fluting in web-offset printing on. It's designed to have small contractile force which is occur by drying of web-offset printing process.View full abstractDownload PDF (2633K) -

JOURNAL FREE ACCESSDaishowa Paper Shiraoi Mill completed onsite Precipitated Calcium Carbonate (PCC) manufacturing facility in June. 2000. We have planed to transfer from acid to neutralized paper making in all paper grades except for news print and liner board. PCC is used to make neutral paper and the decision was made to build an onsite plant. A PCC manufacturing and supply agreement was signed with PCC manufacturer. Specialty Minerals FMT K. K.(SMF), in the summer of 1999.
Specialty Minerals Inc.(SMI), a parent company of SMF, has an excellent reputation as a producer of high quality PCC and is the largest producer with 2.1 milliion tons of PCC at their 55 plants located around the world.
In general, neutralized papermaking can provide many advantages including less degradation over time, higher brightness and opacity, and better printability. On the contrary, some disadvantages include difficulty in keeping machines clean, ink feathering, and high costs. Because of these disadvantages. we have limited to apply neutralized paper making to PPC paper and special grade of fine paper. We. however, were able to overcome these technical problems and, with the exception of newsprint, we have decided to neutralize most paper grades.
At this time, we would like to present a general description of on site PCC plant, and PCC characteristics. Also, we would like to present our experiences in the transfer from acid to neutralized paper making.View full abstractDownload PDF (2097K) -
