Carbon dioxide utilization using a pretreated brine solution at normal temperature and pressure

摘要: Abstract Herein, we discuss carbon capture and utilization processes using industrial wastewater. 5, 10, 30 wt% aqueous monoethanolamine (MEA) solutions were used as the absorbent solution. A pretreated brine solution, in which contained calcium ion with concentration of 21972.64 ppm, was to supply cations. All experiments done under ambient pressure a temperature range between 298.15 K 343.15 K. 0.79, 0.34 0.19 mol CO 2 captured by 10 MEA solutions, respectively. When 100 ml added each saturated 24.65%, 36.96%, 41.65% (mol basis) converted carbonate salts fixation process. To investigate possibility recycle after precipitation step, second absorption performed. As result 0.55, 0.27, 0.16 mol Through X-ray diffraction (XRD) analysis scanning electron microscope (SEM) analysis, it proven that formation possible majority form calcite.
