Chemical Engineering Transactions (CET) is an international, open-access journal focused on original research and review articles in chemical, food, process, and environmental engineering. Established in 2002, it was created to publish high-quality work connected with leading international conferences and has since developed into an internationally recognised publication. Each volume is identified by an ISBN and ISSN, and papers have carried individual DOI numbers since Volume 17. CET is available through Scopus and Google Scholar.

The journal publishes current and archival volumes, with issues presenting research across its engineering disciplines and related areas. Its 2026 Volume 127 focuses primarily on environmental odour monitoring and control, while also addressing applications of odour analysis in indoor air quality, medical diagnosis, and process control. This reflects the journal’s interest in research with relevance across multiple sectors. CET provides information on its aims and scope, editorial board, journal policies, and article submission and publication processes. It is a journal of AIDIC, the Italian Association of Chemical Engineering, and is published by AIDIC Servizi S.r.l.
