Process control developments in the pulp and paper industry.

Membrane Fouling Prevention and Control Strategies in Pulp and Paper Industry Applications: A Review

Membrane separation technologies have recently received much attention, from lab-scale studies to full-scale operations, in the forest industry. However, membrane fouling comprises a signifcant obstacle to their broad application. Thus, to ensure cost-effective operation of membrane separation processes, the improved elucidation of membrane fouling and establishment of e...

Environmental Noise Control in the Pulp and Paper Industry

The number of external noise sources of a paper making line is typically around 80 pcs. The major ones are process and machine room ventilation and vacuum pump exhausts. The noise control targets will dictate the scope and costs of sound attenuation. Considerable cost reductions can be achieved if the noise control design starts at the early stage of a project. Additionally, depending on the no...

Control of Pollution in the Pulp and Paper Industry

Process Optimization and Model Based Control in Pulp and Paper Industry

In this paper we discuss the usage of physical models for diagnostics and process optimization in pulp and paper applications. Specially diagnostics with respect to hang ups and channeling in digesters is described, and how a rigorous model can be used for this, but also for the purpose of MPC, Model predictive control. An example of optimization of a complete pulp mill with respect to mill bal...

Bankruptcy in the Pulp and Paper Industry: Market’s Reaction & Prediction

This paper examines North American pulp and paper company bankruptcies that occurred between 1990 and 2009. We demonstrate that shareholders suffer substantial losses (37%) during the month a bankruptcy occurs. Encouragingly, we show that financial ratios are useful in predicting firm failure and that failed firms are less profitable, more liquidity constrained and higher in debt leverage. Usin...
