Staff

The Infochem staff are one of the most experienced groups in the world working on the application of thermodynamics and physical property models. They have a cumulative experience of over 80 man-years. The key personnel are:

Beryl Edmonds graduated from Sheffield University with a doctorate in thermodynamics and followed this with two years postdoctoral research in information science. She then worked for the Physical Property Data Service (PPDS) of the U.K. Institution of Chemical Engineers of which she became a director. She has been a member of several physical property advisory committees including HTFS, ESDU and DIPPR. She joined Infochem in 1991, since when her technical work has included the application of models for hydrates and asphaltenes, the prediction of properties for new refrigerants and the study of trace elements such as mercury, in petroleum fluids. She has acted as an expert witness for litigation and arbitration.

Tony Moorwood took a first degree in physics and a doctorate in chemical engineering at the University of Erlangen in Germany. He joined the BP Research Centre to be responsible for the thermodynamic software development in BP's thermodynamics project. He then spent a period of time working in petroleum engineering before setting up Infochem Computer Services Ltd. in 1986. Since then he has continued to develop his work in thermodynamics and physical properties. His research activities mainly focus on fluid characterisation and developing models for solid deposition, electrolytes and polar systems, especially those involving associating components.

Richard Szczepanski obtained his degrees in chemical engineering at Imperial College in London. He was then appointed to the post of lecturer where he specialised in problems involving modelling of multi-component systems and phase equilibria. He joined BP Research in 1985 becoming leader of the thermodynamics project. Since joining Infochem in 1988 he has worked on calculation methods, applications of phase equilibria and the development of interface standards.

Xiaohong Zhang obtained a first degree in physics and a doctorate in solid-state physics from Sheffield University. Since joining Infochem in 1997, she has worked on a variety of problems especially connected with characterising complex materials such as crude oils and solid deposition.
