Abstract
In this study, lipid extraction and CO2 capture are combined using N, N-dimethylcyclohexylamine (DMCHA) as switchable polarity solvent. The effects of operation parameters are discussed according to the CO2 absorption/desorption and lipid/DMCHA recovery results. A triphasic models considering lipid, water, and gas phases are established to analyze the kinetic behaviors. The results show that DMCHA is reversible through CO2 absorption/desorption, and the enhanced dispersion of droplets and bubbles in water phase improves the lipid/DMCHA recovery and CO2 absorption/desorption. The triphasic kinetic models fit well with experimental data, and gas–liquid mass transfer is regarded as the rate-determining step. The lower interfacial areas result in the poorer gas–liquid mass transfer for the DMCHA recovery than lipid recovery process.
期刊介绍:
Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
