Techno‐economic comparison of amine regeneration process with heat‐stable amine salt reclaiming units

Abstract Most factories employ an amine gas sweetening process to remove sulfur compounds. During this process, heat‐stable amine salt (HSAS) is generated, which reduces process efficiency. Ion exchange resin and electrodialysis reclamation methods are employed for HSAS removal. However, the equipme...
