Abstract
Emission Minimization of a Two-Stage Sour Water Stripping Unit Using Surrogate Models for Improving Heat Duty Control
Highlights
Sour Water (SW) are aqueous wastes from many operations in oil refineries
Models based on Kriging interpolation were used to substitute sour water strippers in a large optimization of a sour water plant located in Germany [22]
Results obtained by the Response Surface (RS) models are compared with data from an industrial plant
Summary
Sour Water (SW) are aqueous wastes from many operations in oil refineries. Hydrogen sulfide (H2S) and Ammonia (NH3) are the most common SW contaminants, Morado, H. C., et al Emission Minimization of a Two-Stage Sour. Year 2019 Volume 7, Issue 2, pp 305-324 besides eventual presence of phenols and cyanides. SW needs treatment before reuse or discharge, avoiding damages to processes and to the environment [1, 2]. For this purpose, Sour Water Stripper Units (SWSU) are the common process solution for stripping H2S and NH3 and to recover reusable water [3, 4]
