Title:
ALKANOLAMINE-BASED CARBON DIOXIDE ABSORBENT CONTAINING POLYALKYLENE GLYCOL MONOMETHYL ETHER, AND CARBON DIOXIDE ABSORPTION METHOD AND SEPARATION METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/104792
Kind Code:
A1
Abstract:
The present invention relates to the use of an aqueous solution as a carbon dioxide absorbent, the aqueous solution containing a tertiary dialkylalkanolamine as a primary absorbent, a secondary alkanolamine as a speed enhancer, and polyalkylene glycol monomethyl ether as a regeneration promoter. The alkanolamine-based carbon dioxide absorbent containing polyalkylene glycol monomethyl ether and the carbon dioxide absorption method and separation method using same, according to the present invention, not only have an excellent carbon dioxide absorption capacity and a rapid carbon dioxide absorption rate, but also have a remarkably low absorbent regeneration temperature compared with a conventional alkanolamine-based absorbent and thus can significantly reduce the entire energy consumption required for an absorption process, and can also prevent recovered carbon dioxide from being contaminated with moisture and absorbent vapor, owing to the low regeneration temperature.
