(212d) Continuous Millifluidic Liquid-Liquid Extraction: Digital Design and Development
AIChE Annual Meeting
Monday, November 14, 2022 - 4:24pm to 4:42pm
In this work, we present and implement a workflow for solvents screening and selection, batch and flow extraction experimental design, and the determination of volumetric mass transfer coefficient and digital design for extractor design for 2-chloroethyl isocyanate, ISO, a reagent in the synthesis of Lomustine. Lomustine is an anti-cancer drug that was used to treat brain tumors and Hodgkinâs Lymphoma . The incorporation of the liquid-liquid extraction step in this process will allow for the continuous purification of the Lomustine intermediate prior to the second synthesis step .
In this study, correlations were implemented to provide predictions of the system performance beyond what was measured experimentally. Factors such as the effect of changing volume ratios on droplet size and the impact of changing residence time on volumetric mass transfer coefficient were investigated to explore the design space more fully and ultimately develop a more robust extraction process.
To our knowledge, this is the first time that this kind of analysis of the extraction parameter estimation, model selection and discrimination, and digital design for this system. The work that was conducted provide valuable tools to predict volumetric mass transfer coefficient by using dimensionless groups and the resulting extraction simulations to determine feasible operating spaces and extractor design.
