Career Summary

Biography

Since completing my bachelor and master’s degrees in chemical engineering, I entered industry and worked for one of the major petrochemical companies in the Middle East for 6 years.

My main areas of expertise in the petrochemical and fertiliser industries are chemical plant design, failure analysis, chemical reactor design and modelling, environmental engineering and emission abatement, drying and rotary dryer design and modelling, crystallisation and prilling, heat exchange, absorption and stripping columns, steam drums and boilers, turbines and compressors, particle handling, transportation and storage.

I am a senior chemical engineer, currently undertaking a PhD at University of Newcastle under supervision of Dr. R. Moreno-Atanasio and Prof. G. Evans. Although my background indicates that I am an industrial person used to dealing with large scale facilities in very harsh environments, I've become really fascinated with research on very small scale apparatuses in the friendly and gentle environment of our university.

My research activities at the University of Newcastle are mainly focused on the analysis of particle-particle and particle-fluid interactions in fluidized beds. This work requires deep understanding of solid and fluid mechanics as well as computer programming ability. We use Discrete Element Method (DEM) to simulate particle motion and relative interactions. It is really interesting to look at some natural phenomena occurring in our daily life from many different windows and work out how science is able to describe them. If you’re still doubt, please look at this video

© 2016 Elsevier B.V. Rapid advancement in computer technology makes it possible to perform simulations of large particulate systems using Discrete Element Method (DEM). However, it is still a challenge to adjust the DEM simulation parameters, especially the interparticle forces, in order to obtain rational results. Many of these forces diverge as the distance between particle surfaces approaches zero. Therefore, a cut-off distance needs to be considered in order to avoid such a problem. This work presents the results of the computational analysis of the influence of the cut-off distance, which is required to avoid the divergence of the van der Waals force, on the collision of a single particle against a flat surface. Hence, the effect of the cut-off distance on the coefficient of restitution, collision duration and maximum overlap has been studied. In addition, we have theoretically derived an expression for the minimum velocity under which the particle remains adhered to the surface (critical velocity) as a function of the cut-off distance. The simulation predictions of the critical velocity are within the range of experimental data published in the literature. We demonstrate that the cut-off distance has a profound influence on particle rebound and therefore, a careful selection of this parameter should take place when simulating bulk particle behaviour. Given that the hydrophobic force is usually simulated using the same expression as the van der Waals force, the results presented here could also be considered in the context of the simulation of the hydrophobic force.

The nitric acid plant of a domestic petrochemical complex is designed to annually produce 56,400 metric tons (based on 100% nitric acid). In the present work, radial-flow spherical bed reactor (RFSBR) for selective catalytic reduction of nitric oxides (NO x ) from the stack of this plant was modelled and compared with the conventional radial-flow reactor (CRFR). Moreover, the proficiency of a radial-flow (water or nitrogen) membrane reactor was also compared with the CRFR which was found to be inefficient at identical process conditions. In the RFSBR, the space between the two concentric spheres is filled by a catalyst. A mathematical model, including conservation of mass has been developed to investigate the performance of the configurations. The model was checked against the CRFR in a nitric acid plant located at the domestic petrochemical complex. A good agreement was observed between the modelling results and the plant data. The effects of some important parameters such as pressure and temperature on NO x conversion were analysed. Results show 14% decrease in NO x emission annually in RFSBR compared with the CRFR, which is beneficial for the prevention of NO x emission, global warming and acid rain. © 2013 Taylor & Francis.
