•Technical Paper: Amine Purification System (AmiPur®) – Continuous Heat Stable Salts Removal From Amine Solutions
1. Introduction
Amine scrubbing solutions are used to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gas streams and LPG in many oil refineries and natural gas conditioning plants. Due to its high selectivity to H2S, Methyldiethanolamine (MDEA) is most commonly used to remove H2S in the presence of CO2 from gas streams and LPG.
Amine plant operational problems, such as excessive foaming, corrosion, and capacity reduction, are often attributed to the accumulation of amine heat stable salts. These heat stable salts lead to costly maintenance problems such as corrosion, frequent filter replacement, foaming in the absorber column, absorber tower plugging, heat exchanger fouling and a reduction in the amount of amine available for gas treating.
Continuous amine purification is being increasingly recognized as the most effective solution for HSS related problems. The benefits of continuous HSS removal go beyond limiting the level of impurities in the amine loop. A continuous on-line purification system helps to ensure a stable and uniform gas conditioning operation where contaminant level in the amine solution is prevented from building up, thus minimizing the rate of corrosion. It also ensures that amine unit operation is reliable and provides the designed gas treating efficiency.
Developed by Eco-Tec Inc. Canada in 1998, AmiPur® (Amine Purification System) uses anion exchange technology to continuously remove heat stable salts. Therefore, it ensures reliable operation of amine plant.
