Dr Nejat Rahmanian

BIOGRAPHY +

Dr Nejat Rahmanian is a Senior Lecturer in Chemical and Petroleum Engineering and MSc/MEng Program Leader in the area of Chemical and Petroleum Engineering in University of Bradford. He is also currently a member of the Board of Faculty of Engineering. He has about 20 years experiences in both academia and industry.

Nejat has hold four patents, published three chapter books, over 70 journal articles and refereed-conference proceeding. He is actively involved in research in two major areas of particle technology and oil/gas processing. In particle technology his main focus is on granulation and particle characterisation and in oil/gas processing his current focus is CO2 capture, transportation and storage, process modelling and simulation of hydrocarbon processes. He has been returned in UK REF2014 (Research Excellence Framework) with 4 out of 6 Very Good high quality papers.

He completed supervision of 12 MSc and 20 MEng and final year research projects and supervised jointly or individually 6 PhD projects during his academic career in various places.

He was visiting professor at Institute of Chemical Technology, Mumbai in 2014/15. He is also a member of UKCCR (UK Carbon Capture Research) and Gas Processors Association Europe. He has ongoing research collaborations with industries and academic institutions in the UK, Canada, the Netherlands, India, Turkey, Iran, Oman, Saudi Arabia and Malaysia.

Nejat obtained his BSc and MSc in Chemical Engineering in 1989 and 1993, respectively. His MSc was an industrial research project on urea prilling process. He continued his study at University of Leeds where he obtained his PhD in 2010. His PhD was on the "Scale up of Granulation Process", a project sponsored by Proctor and Gamble, Borax Europe Ltd, Pfizer, Hosokawa Micron, and EPSRC.

Nejat has also worked continuously nearly 8 years (1997-2005) in Petropars Limited Company as a Process and later on as Senior Process Engineer for development of South Pars Gas Field Development, the biggest gas retograte-condenaste reservoir in the world. During this, he worked closely with International Engineering and Construction Companies in Malaysia, Japan, South Korea, and UK for development of the field. He also collaborated part time with national petrochemical companies.

Nejat was a Senior Lecturer in Chemical Engineering in Universiti Teknologi PETRONAS (Malaysia) between 2011-2013 before he joined University of Bradford in mid-2013.

He has received Gold Medal at 24th International Invention, Innovation and Technology Exhibition (ITEX 2013). He has also awarded title as "Best Technical Contribution to the Field of Granulation" from EFCE, European Federation of Chemical Engineers, in 2007. He also received award entitled ''Young Researchers in Particle Technology'' from IChemE Particle Technology Subject Group in 2008 as the finalist. So far, he has received ten travel bursaries and scholarships and six prestigious awards.

[4] 2D and 3D structure characterization of particles using SEM and X-ray micro tomography, respectively. This is followed by Image Processing.
[5] General chemical engineering subjects such as water and wastewater analysis.
[6] Multi-disciplinary subjects such as design of diabetic shoes and self-cleaning fabrics.
