We had serious corrosion issues in the amine regeneration column of the TGTU. We also measured significant HSS levels in the amine solution. We are about to replace the quench tower in our TGTU, upstream of the amine absorber. We are considering installing a demister in the overhead of the quench column, to increase the system’s capability to avoid SO2 entrainment in the amine system. We assume that the cons for doing this step are increased pressure drop and risk of sulphur deposits in the demister. Is it a common practice to install a demister in the TGTU quench tower overhead? Does somebody have experience of doing this? Any known issues with this demister?
