Abstract:
Sour crude natural gas requires treatment with amine-rich (%) scrubber solutions to neutralize the sour gas to sweet gas. Cation-exchange chromatography with suppressed conductivity detection monitors the concentrations of alkanolamines, amine byproducts, and corrosive dissolved salts to assure neutralization capacity and limit corrosive ions. However, these sample are challenging due to the high concentration of amines and their similar structures. In this application, diluted alkanolamine solutions are separated on a recently introduced high-performance cation-exchange column with improved separation technology that elutes the alkanolamines between the singly and doubly charged cations. The alkanolamines are detected by suppressed conductivity.
