Plantwide Optimization of a Pulp Mill Process

An economic optimization study of a pulp and paper mill is presented. Costs and revenues associated with all unit operations are identified to formulate a suitable objective function. The existing control structure of the pulp mill is analyzed and used to develop an optimization-relevant model through a series of step tests. This model is then used with the objective function and the informatio...

Cardiovascular mortality among pulp mill workers.

A mortality study, concentrating on cardiovascular mortality, was undertaken among Finnish sulphite mill workers exposed to sulphur dioxide and sulphate mill workers exposed to hydrogen sulphide and organic sulphides. They had been employed continuously for at least one year between 1945 and 1961. National death rates were used for comparison and mortality was followed up until 31 December 1981...

Bioremediation of paper and pulp mill effluents.

Pulp and paper mill effluents pollute water, air and soil, causing a major threat to the environment. Several methods have been attempted by various researchers throughout the world for the removal of colour from pulp and paper mill effluents. The biological colour removal process uses several classes of microorganisms--bacteria, algae and fungi--to degrade the polymeric lignin derived chromoph...

Energy Genration from the Biomass in Pulp and Paper Mill

The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills combines sedimentation, biological treatment, chemical precipitation, flotation and anaerobic treatment, and the specific combination of techniques is determined by the local con...
