Salt Deposition Risk Monitoring
Salt deposition in crude and FCC fractionator overheads and hydroprocessing effluent trains can lead to various operational problems. It is critical to identify when the unit is operating in a condition with a high risk of salt deposition. If unmitigated salt deposition occurs, it can lead to an increase in corrosion and equipment fouling/plugging. This can cause loss of integrity, leading to potential process safety and economic risks.
Users need to be able to present the results as a continuous signal, as “percent of time at-risk.” This can prove difficult when an engineer must manually analyze data that resides in multiple unaligned systems, including lab data. Before Seeq, a thorough analysis required engineers to manually combine data from multiple sources and enter it in a spreadsheet, spending hours or even days formatting data, filtering it, and removing anything non-relevant.
