International Journal of Chemical Engineering publishes papers on technologies for the production, processing, transportation, and use of chemicals on a large scale. Studies typically relate to processes within chemical and energy industries, especially for production of food, pharmaceuticals, fuels, and chemical feedstocks. Topics of investigation cover plant design and operation, process design and analysis, control and reaction engineering, as well as hazard mitigation and safety measures.

As well as original research, International Journal of Chemical Engineering also publishes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
