Mohammed Alaqqad earned his PhD degree in 2011 in chemical and biological engineering from the University of British Columbia (UBC), Vancouver. He received his undergraduate education from the American University of Sharjah, Sharjah, United Arab Emirates, where he earned his Bachelor of Science degree in chemical engineering in 2007. Alaqqad developed a methodology to characterize the permeability and dispersion of flows through compressible wood-chip beds. This work is motivated from one unit operation in the Kraft process in the pulp and paper industry, namely the chemical digester. Thus, this research will be a guidance to improve computer models of digesters as well as to help optimize present digester operations in order to achieve high quality and yield of the pulp produced. Alaqqad also utilized electrical resistance tomography (ERT) to develop 3D volume visualization schemes and imaging techniques of multiphase flows in these compressible wood-chip beds. This work will ultimately give us a better understanding of what goes on inside these multiphase reactors and flow systems, taking us to the next level of industrial development by: obtaining internal industrial data, obtaining 3D flow/reactor visualization, monitoring reactors operation and performance, and maintaining high product quality and yield.
