Abstract:
Sour water in refineries is a waste water which results of atmospheric or vacuum crude columns. Sulphides and Ammonium are typically components in this stream which needs to be removed before this water can be reused for other purposes. In sour water stripping towers the H2S and the N3 is removed by adding heat to the water and the gases are exiting the tower top. It is necessary for this stripping process that the usage of energy and additional chemicals have to be kept at a minimum to run this process efficient. Measuring the residual content of H2S and Ammonia at the bottom of the stripping tower helps refineries to reuse water in a more efficient way and safe therefore money and resources. The new Process Analyzer of Metrohm measures these parameters fully automated and unattended so a 24/7 monitoring of the stripper and the most efficient control of energy and reagent dosing is ensured.
