abstract={An optimization of the power consumption of six pumps in the screening system of Hylte
Mill's TMP plant is conducted. The calculations are done with a model for pressure drop in
pipe systems, given in a calculation instruction for pipe friction losses for pulp. Used
calculation model is also tested versus experimental values from the literature, in order to
examine the validity. Compared to literature data, the model seems to give somewhat high
pressure drop for TMP suspensions. There is a lack of experimental data for mechanical pulps
and studied graphs date back to the 1970's. Measured values from the TMP plant are tested
versus theoretical pressure and power of the current pumps. A good agreement between
measured and theoretical values is noticed.
A reduction in power consumption of 150 kW seems very realistic by minimizing the pressure
reduction over the control valves and with the installation of speed controlled pumps in
studied system. This corresponds to 44% of today’s power consumption. All studied pumps
show clear saving potential, although the required pressure is overestimated. None of the
suggested pumps is limited by the start-up resistance. An Excel based program for automatic
pressure calculations in a pipe system and with graphical pressure drop representation, has
been developed. A basis for further development of a program based pressure drop calculation
and graphical technique is given, partly through the developed program, partly through
suggestions given in the report.},
