Heat Stable Salts Effects in a Natural GasSweetening Plant

Natural gas demand increasement, needs efficient gas processing methods and plants.Gas sweetening is one of the main processing steps in natural gas conditioning. A gassweetening plant, usually facing with various unwanted problems, which causes plantto operate in abnormal conditions. Generation of a special kinds of salts in aminesweetening systems, called Heat – Stable Amine Salts (HSSs) can affect gassweetening plant. In this study we discussed about HSS’s origin, their generationmechanism and methods used for their elimination. Finally we simulate a common gassweetening plant in Aspen HYSYS simulator and investigate the effect of HSSspresence in the plant; Results show that HSSs cause some inappropriate effects, likeincreasement in the reboiler duty and off – spec sweet gas
