Fluid Separations

About us

Separations lie at the heart of chemical engineering. Virtually all the chemical process industries rely on separation processes, such as distillation, absorption, adsorption, extraction, filtration and membrane separations, to purify raw materials and products, recover intermediates, and to remove by-products and impurities from a wide range of feeds.

IChemE’s Fluid Separations Special Interest Group is concerned with the development, design, operation and control of fluid separation processes and equipment. The need to develop more efficient and economic separation technologies, including more complex, integrated and hybrid units, demands that we continue to develop and improve these technologies in both new designs and process revamps. Increasingly important are the issues of energy efficiency, sustainability, health, safety and environmental impact in the context of separations.


  • provide a forum for professional engineers with an interest in fluid separations to meet and discuss their technical and business challenges and developments
  • encourage learning and sharing of expertise through workshops, technical meetings and conferences
  • improve the quality and relevance of research in fluid separations
  • foster and improve links between separations specialists working in academia and industry.


  • technical meetings, conferences and web-based workshops on specific separations topics
  • newsletter featuring reports and previews of events, and other relevant items of news
  • annual research event showcasing the work of PhD students and young researchers to industry and academia
  • grants to support student attendance and participation in conferences and short courses
  • representation of professional interests via forums including the European Federation of Chemical Engineering Working Party on Fluid Separations.
