Impact of TMP refining line interruptions and reject refiner operations on pulp and paper variability
Source abstract
Abstract
This article develops a method for correlating TMP operations with pulp quality, and ultimately with paper quality, by focusing on process fundamentals such as specific energy and refining intensity. The case study is an Eastern Canadian newsprint mill that experiences variability in paper strength and porosity. Frequent interruptions in the four refining lines greatly affect the reject refining specific energy and other key parameters, many of which are not measured directly and must be calculated from other variables. Using multivariate analysis and other statistical tools, it was possible to link pulp quality back to the TMP and reject refining operations, taking into account the number of lines in operation, plate age, and process lags. Furthermore, it was possible using multivariate analysis (MVA) models to correlate roughly half the variability in final paper quality with the refining operations.
