A New Experimental Pulp Digester Installation with Separate Steam Supply

Part I Literature Survey Up to now, few articles have been written on the subject of Experimental Pulp Digester Installations. In our searches we have been able to find information concerning only The Pulp and Paper Research Institute of Canada in Montreal, P.Q., Canada, The Chemical Pulp Experimental Department of the Central Laboratory in Finland, and a sulfite digester for research and instruction at the University of Washington at Seattle, Washington, U.S.A

Implications of Trade Trends Upon Canada-US Border Infrastructure

The transportation and inspection agencies that build and operate border infrastructure are engaged in a constant process of facility planning, wrestling with decisions about where to invest limited resources. The existing situation at a facility is obviously influential—e.g., traffic volumes in excess of a facility’s capacity; subpar workplace conditions; excessive maintenance costs for a decrepit facility. But equally important is the need to consider future conditions, such as the traffic forecast. This article discusses the volume of trade forecasted to occur at eight major ports-of-entry (POEs) along the Canada – U.S. border

SUITABILITY OF NIGERIAN CORN HUSK AND PLANTAIN STALK FOR PULP AND PAPER PRODUCTION

Wood is a prominent raw material in the production of pulp and paper, but due to the impact of forest depletion on the environment worldwide, research is being focused on non-wood sources as alternative sources of fibre and as a solution to destruction of the environment. The aim of this study therefore, is to investigate the suitability or otherwise of corn husk and plantain stalk which are abundant agro-waste materials in Nigerian environment in pulp and paper production. The pulping of corn husk and plantain stalk was achieved through Chemical Pulping process (Soda pulping) and the pulps obtained were analyzed for their chemical compositions. Also, the scanning electron microscopy (SEM) was used to analyze the surface morphological structure of the pulps produced. The resulting pulps were then used for papermaking and the Mechanical strength of papers obtained was determined. The results of chemical composition analysis for the pulp obtained from corn husk were (3.57%, 41.23%, 10%, 12.04% and 23.00 %) while that of plantain stalk were (11.19%, 57.86%, 10%, 4.60% and 35.96%) for Ash content, Cellulose content, Moisture content, Lignin content and Pulp yield respectively. The result of Mechanical strength analysis of the paper produced are (66.04 g/m2, 0.30 mm,5.33 Nm/g,12.83Nm2/g,0.13 N/mm2,2.7 mm) from corn husk while that of plantain stalk are (30.99 g/m2,0.08 mm,1.25 Nm/g,5.20Nm2/g,2.95 N/mm2,2.20 mm) for Grammage, Thickness, Tensile index, Tear index, Modulus of Elasticity and Elongation at break respectively. The SEM images analysis showed that there is a more condensed and packed arrangement of fibre in corn husk than plantain stalk. The overall results showed that Corn husk and Plantain stalk have a promising potential as alternative source of fibre in paper making industry

The Review of Economic Performance and Social Progress 2001: The Longest Decade: Canada in the 1990s

In this chapter, Daniel Schwanen addresses the impact of the major trade liberalization efforts undertaken by Canada and its trading partners beginning with the Canada-U.S. Free Trade Agreement (FTA) in 1989. The author focuses in particular on the question of whether liberalized trade could have been a factor behind the emergence of greater inequalities in Canada in the 1990s. The author divides Canadian manufacturing industries into five groups according to their sensitivity to trade liberalization in the 1990s and to the direction taken by exports and imports following the opening of trade. Schwanen concludes from this exercise that more open trade may have contributed to inequalities in Canada, by favoring certain groups already doing relatively well, while being unfavourable to many less-skilled and lesser-paid groups.Trade, Inequality, Manufacturing, Canada, FTA, NAFTA, Free Trade, Free-trade, Trade Liberalization, Free Trade Agreements, United States, US, U.S.

Characterization of air emissions from pulp and paper mill facilities in atlantic Canada

A kraft pulp mill that operated in Pictou (KPMP), Nova Scotia for more than 50 years is considered a major source of environmental pollution, although its air emissions have not been widely studied. To address this gap, this research compares air releases from the KPMP with other industrial facilities releases and with regulations. A comparison between nine different pulp and/or paper mills in Atlantic Canada between 2002-2019 suggested that pulp mills emit higher pollutant loads than those producing paper and that the highest release was fine particulate matter (PM2.5) from the KPMP. The KPMP releases were also 10 and 1000 times the releases of a tire manufacturing facility and a coal-fired power plant nearby, and results suggest that the KPMP was likely the primary source for high PM2.5 concentrations in Pictou. Air quality PM2.5 management levels in Pictou became green following the installation of a precipitator by the KPMP in 2015.Agencia Nacional de Investigación e InnovaciónCanadian Standards Associatio
