USING METHYLDIETHANOLAMIN COMPOSITION OF THERMOSTABLE CLEANING SALTS
Description
The 30% aqueous solution of used methylmethyldiethanolamine (MDEA) can be regenerated and reused for gas purification, and its residual part can be used as a secondary raw material in another area of production. A 30% aqueous solution of MDEA is driven under vacuum conditions and separated from water. MDEA and its destroyed part remain in the column. The methods of cleaning alkanolamines used in gas purification from thermostable salts and extending their working time were studied.
