Project Title: Predictive Wear in Slurry Pipelines
Hydrotransport pipelines in the oilsands
industry experience accelerated wear due to varying combinations of abrasion,
impingement, and corrosion. These processes cause pipelines to wear
through, incurring profit losses due to downtime and spillage.
To date little is understood regarding the effect of flow parameters on these
wear processes. Consequently, maintenance engineers have thus far been
unable to predict the lifespan of a section of pipe (for maintenance scheduling),
based on slurry flow parameters.
The objectives of my work are: (a) to seek to quantitatively determine the
effect of major flow parameters which contribute to wear processes, (b) to
identify the flow patterns (and thus, the wear processes) occurring at various
locations in a pipeline, and (c) to take this research a logical step further
by looking at slurry pumps (time allowing).
To complete the given objectives, I intend to use several techniques, listed
below.
Progress to Date:
To date, a lab-scale slurry pipe loop has been built (by a research
colleague). I have prepared the data acquisition unit, wired all the
sensors and electronic components together, and researched and ordered
interfaces for pump and mixer motor control. I have also researched the
harmonic properties of a wall shear sensor developed by one of my
colleagues. From this research I have submitted a paper to the CSME forum
in
Expected completion date: 2011
