The accumulation of heat-stable salts (HSS) in the gas sweetening amine units causes several problems, including foaming, corrosion, and fouling. Herein, a simple and efficient electromagnetic salt removal (EMSR) process was proposed for the separation of HSS from industrial lean amine solution. In this process, HSS were separated through an electro polarization mechanism instead of electrosorption. For this purpose, a lab-scale concentric flow setup was fabricated using aluminum conduit and rod as an anode and cathode, respectively. The effects of the process operational parameters, including flow rate, applied voltage, residence time, and pH were investigated. At the best-operating conditions, a maximum of 15 % HSS removal percentage was achieved in one pass having the power consumption of 0.003 Wh/L. This study demonstrated the potential usage of EMSR for industrial applications.

气体甜味剂胺单元中热稳定盐（HSS）的积累会引起一些问题，包括起泡，腐蚀和结垢。在此，提出了一种简单有效的电磁除盐（EMSR）工艺，用于从工业稀胺溶液中分离HSS。在此过程中，通过电极化机制而不是电吸附将HSS分离出来。为此，使用铝导管和棒分别作为阳极和阴极来制造实验室规模的同心流装置。研究了工艺操作参数（包括流速，施加电压，停留时间和pH）的影响。在最佳操作条件下，功耗为0.003 Wh / L的一次通过最多可实现15％的HSS去除率。
