MINIMIZING WATER CONTENT IN ETHANOLAMINE PRODUCT STREAMS

摘要

Systems and method are provided for reducing the water content from approximately 0.15% -0.19% by weight to approximately 0.01-0.03% by weight in an ethanolamine product stream in a non-reactive distillation column. The reduced water content can be achieved by increasing the processing conditions at the drying column by approximately 5% to approximately 20%, more preferably to approximately 10%. The increased processing conditions at the drying column can result in an increased bottom stream flow rate and an increased reboiler duty. The reboiler duty of the drying column can be increased by up to 2 % to achieve said level of water content. The bottom stream flow rate can be increased by up to approximately 12% to achieve said level of water content.
