用于从胺吸收剂除去热稳定胺盐的方法
摘要：
用于从二氧化碳(CO2)捕集过程所用的胺吸收剂除去热稳定胺盐的方法和系统，所述方法包括：从CO2捕集过程取出含有热稳定胺盐的胺吸收剂；使取出的含有热稳定胺盐的胺吸收剂经受残余CO2除去步骤(117)；使来自残余CO2除去步骤的胺吸收剂(120)经受分离步骤(116)，以将热稳定胺盐(124)与胺吸收剂分离；和使具有降低的热稳定胺盐浓度的胺吸收剂(122)返回至CO2捕集过程。
摘要（英）：

A method and a system for the removal of heat stable amine salts from an amine absorbent used in a carbon dioxide (CO2) capture process, the method comprising: withdrawing amine absorbent containing heat stable amine salts from the CO2 capture process; subjecting the withdrawn amine absorbent containing heat stable amine salts to a residual CO2 removal step (117); subjecting the amine absorbent (120) from the residual CO2 removal step to a separation step (116) to separate heat stable amine salts (124) from the amine absorbent; and returning the amine absorbent (122) having a reduced concentration of heat stable amine salts to the CO2 capture process.
