TN122: Separation of Heat Stable Amine Salts in Methyldiethanolamine (MDEA) SolutionsUsing High-Pressure IC
Description
Sour gas is treated with amine and recycled amine (scrubbing) solutions to absorb toxic and undesirable H2S and CO2 create sweet natural gas. Salts of organic acids and sulfur species, heat stable amine salts (HSAS) can concentrate over time. Analysis of these HSAS are needed to assess the efficiency of scrubbing solution and can be quite challenging. In this technical note, HSAS in methyldiethanolamine (MDEA) were separated with high efficiency on a 2 mm i.d. IonPac AS11HC-4μm column using a high pressure ion chromatography system.| Market: | Petrochem, Oil and Gas |
