Description

Electromagnetic Field CO2 Capture System Using Ferrofluid {DEVELOPMENT OF CO2 CAPTURE USING FERROFLUID WITH ASSISTANCE OF ELECTROMAGNETIC FIELD} Device of CO2 capture using ferrofluid with assistance of electromagintic field The present invention relates to a system for capturing carbon dioxide under an electromagnetic field using a magnetic fluid. Specifically, the invention relates to a system for capturing carbon dioxide by controlling electromagnetic field conditions using a magnetic fluid containing magnetic nanoparticles and a surfactant. Recently, there has been growing interest in carbon dioxide ( CO2 ) capture and utilization devices applicable to various energy and industrial systems. In particular, research is underway to develop various methods and technologies to improve CO2 capture efficiency and optimize energy consumption to increase storage capacity. Despite various patents and studies on CO2 capture, its application to actual systems and cycles is limited, mainly due to compatibility issues between the working fluid and reactor materials or bubble columns, as well as issues regarding chemical and thermal stability. As a solution to this, a CO2 capture reactor integrating magnetic fluid and electromagnetic field is expected to enable more efficient CO2 capture and has the potential to be a solvent that can be customized for specific industrial applications. Magnetic fluids can increase the interfacial area between the gas and liquid phases to improve the CO2 absorption rate, and electromagnetic fields can be used to optimize the dispersion and stability of bubbles by adjusting the properties of the magnetic fluid. Figure 1 illustrates a carbon dioxide ( CO2 ) capture system of the present invention. FIG. 2 illustrates a carbon dioxide ( CO2 ) capture system operated under an electromagnetic field using a free body according to one embodiment of the present invention. Figure 3 illustrates the CO2 absorption reaction in a carbon dioxide capture system operating under an electromagnetic field and the operation process of a magnetic fluid together with a magnetic field. Figure 4 shows CO2 without the application of magnetic nanoparticles. ­ The CO2 bubble size distribution was plotted by simulating the capture system. Figure 5 shows CO2 when magnetic nanoparticles are applied. ­ The CO2 bubble size distribution was plotted by simulating the capture system.
