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.
