An Approach for Solvent Selection in Extractive Distillation Systems Including Safety Considerations
The
selection of solvents in the chemical industry is typically
based on performance and economic considerations. Other relevant aspects,
such as the safety implications of a given solvent, are generally
left for consideration after the design of the process has been completed.
In this work, an approach for solvent selection including safety considerations
at the design stage of the process is presented. The safety component
is included through a consequence analysis using an average distance
for the risk of death as the major parameter. The approach is applied
to the design of extractive distillation systems, for which a preselection
step for the solvent is used, followed by the formulation of a multiobjective
optimization problem in which both economic and safety aspects are
taken into account. The approach is applied for the purification of
bioethanol, for which solvents that offer the best costāsafety
compromise are identified
