Abstract This paper provides an analysis of pollution prevention, treatment and cure with respect to solvent-based processes. It is postulated that, in new processes, considering environmental constraints in the early stages of process design can prevent pollution due to inefficient recovery of solvents or inefficient separation by solvents. Pollution in existing processes can also be prevented through early treatment that includes assessment of causes and effects of future changes in process conditions and/or environmental regulations. Pollution cure is more difficult, since the process is already violating some environmental constraints and any solution also needs to satisfy social and economic constraints. A technique for pollution prevention, treatment and cure that is based on the use of computer-aided tools is presented. Application of the technique is illustrated through a case study that highlights the important steps of the solution approach and serves as a proof of concept.
