Canadian Refiner replaced the Shake Test with on-line UOP Mercaptide Sensors to monitor the extent of Merox caustic regeneration. Mercaptide Sensor use resulted in continuously trended data, reduced caustic exposure, and proactive process variable optimization, while vastly reducing off specification incidences and unnecessary bulk caustic replacements.
