FIELD: process engineering.
SUBSTANCE: invention is designed for continuous distillation separation of the mix containing one or several alkanolamines. This application describes devices and methods of continuous distillation separation of the mix containing one or several alkanolamines. Separation is performed in one or several columns with web while alkanolamines are extracted as side running.
EFFECT: higher purity.
