Experimental Study on MDEA Regeneration by Vacuum Membrane Distillation

Abstract:

Aqueous solutions of N-methyldiethanolamine (MDEA) are widely used in the sweetening process of sour gases, but the solutions deteriorate due to the contamination in their use process, and the deficiencies of the technologies for the regeneration of disabled solution restrict their development. A vacuum membrane distillation (VMD) technique for the regeneration of MDEA solutions was proposed and experimentally investigated.It is studied the effect of change in solution temperature on its regeneration efficiency and the distillation flux. From the chromatograms it is known that the best temperature for regenerating waste solution by VMD is 70 °C,and the regeneration efficiency can be up to 98% at this experimental conditions.
