Systems and methods for producing a triethanolamine product stream with a degree of purity of 85% by weight from the triethanolamine distillation columns in a reactive distillation process without blending the TEA 99 product stream with a pure cut of DEA 99%. The desired triethanolamine product stream can include 85% TEA and 15% DEA and can be created by using a dummy stream at the triethanolamine column via (1) increasing the bottom stream flow rate of the diethanolamine column, and/or (2) reducing the TEA 99 product stream at the triethanolamine column. The bottom stream flow rate at the diethanolamine column can be increased by 80 kilograms per hour and the triethanolamine product stream flow rate can be reduced by 500 kilograms per hour. This process can result in up to a 23 degree temperature reduction in the triethanolamine column, which can improve the color properties of the triethanolamine product.
