Abstract
Abstract To produce Morpholine (Mp) in an environmental friendly manner, bipolar membrane electrodialysis was used to convert Mp sulfate into Mp with 0.3 mol/L Na 2 SO 4 as electrode supporting solution. The result indicated that a high current efficiency and low energy consumption can be obtained when Mp sulfate solution concentration is at the range of 0.15–0.22 mol/L, current density at the range of 20–30 mA/cm 2 with BP-A-C-BP cell configuration. Product yield rate was increased with the increasing current density and feed concentration. At the same time, BP-A-BP and BP-C-BP cell configurations were also examined. A lowest process cost of 1.20 $/kg and energy consumption of 4.27 kW h/kg was obtained through BP-A-BP configuration compared with other types. This process was not only cost-effective, but also environmental benignity.
