PSEP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering concerned with the safety of industrial processes and the protection of the environment.

Papers that deal with new developments in safety or environmental aspects, demonstrating how research results can be used in process engineering design and practice, are particularly encouraged. Experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research will also be considered. The journal is especially interested in contributions that extend the boundaries of traditional engineering as well as in multidisciplinary papers.

Papers related to environmental protection must take an integrated pollution control approach, demonstrating clearly that any proposed treatment method does not simply transfer pollution from one environmental medium to another, for example, from air to water or from water to solid waste. All such papers must discuss how any treatment effluents, spent adsorbents, etc., can be treated or disposed of safely, avoiding transfer of pollution to another environmental medium.

For environmental protection, papers that are outside the scope are those that lack engineering aspects, including those that:

  • use experimental techniques primarily to prepare and/or characterise various materials without considerations of process engineering design and practice;
  • present primarily laboratory experiments of the effects of different parameters on behaviour of materials and pollutants (e.g. pH, temperature, mass of adsorbent, etc.) without further insights into the implications for engineering design and practice;
  • focus primarily on adsorption models and curve fitting (e.g. Freundlich, Langmuir etc.); and
  • contain only chemical, physical and/or thermodynamic analyses.
