Design of a novel sour water stripping unit

This study focusses on the design and simulation of sour water stripping (SWS) unit in the refinery setup for the reuse of sour water. In this study, process simulation has been performed to analyze the energy saving and cost reducing prospects in the sour water stripping unit. First, a base case design has been simulated using a reference sour water stripping unit data. The developed model is validated against the plant data in order to ensure the model validity. A novel design has been proposed in this study that can reduce the energy requirement by 53 % compared to the conventional designs. The results of this study provide a meaningful analysis in terms of energy and economic considerations to improve the performance of the sour water units in the refineries.
