摘要:
Systems and method are provided for reducing the water content in ethanolamine product streams from approximately 0.15%-0.19% by weight of water to approximately 0.02 to approximately 0.04 by weight of water. The reduced water content can be achieved by increasing the processing conditions at the monoethanolamine column by approximately 5% to approximately 20%, more preferably to approximately 10%, and by adding a dummy stream to the monoethanolamine column, which can be recycled to the reactor. The increased processing conditions and dummy stream at the monoethanolamine column can result in the following to achieve said water content: (i) the bottom stream flow rate increase by up to approximately 18.9%; the reboiler duty can be increased by up to 47.9%; and (iii) the condenser duty can be increased by up to approximately 52.5%.
