UBC Partner

PSL maintains strong ties to UBC its main R&D partner. PSL licenses technology developed at UBC by the Department of Mechanical Engineering. For more than a decade, the UBC industrial process modelling group has been developing numerical models in primary industries. They pioneered process modelling in recovery boilers in the early 90's and extended this work to most of the major equipment in the Kraft process. The process models, which have been developed, are tailored to assist mills to resolve complex industrial problems. The models are applied to mills operating capital-intensive equipment in order to reduce costs and eliminate unscheduled down time. The outcome of this effort is to:

History of Recovery Boiler Model

A large scale recovery boiler model development program was developed at the University of British Columbia. External collaborators includes Paprican, IPST, OSU, Industry Canada, and the paper industry. As a result, UBC is now recognized as a world leader in recovery boiler modelling. The UBC model is available to industry through Process Simulations Ltd. The UBC recovery project involved two closely related parallel tasks:

  1. development of mathematical models to simulate the flow, combustion and chemistry
  2. measurements both in actual recovery boilers and in physical models of recovery boilers

The UBC group collaborated closely with Paprican, which performed the measurements in actual recovery boilers. This was a major strength of the project, as understanding the complex physics of the flow is crucial in obtaining meaningful results. The combination of the mathematical modelling and measurements have also provided a means for verification and validation of the computations. Approximately fifty person years of work (including graduate student and UBC staff time) has been invested in the development of the mathematical model. External funding for the project has exceeded $2.5 million and has been obtained from a variety of sources, including the US and Canadian governments and the Weyerhaeuser Foundation. PSL is currently extending the model development and has also applied the model successfully to bark boilers.
