Patent number: 11092561Abstract: The invention comprises a method and an analysing system for determining a quality of a hydrocarbon fluid. In an example, the electrical resistivity of the fluid is determined by means of a sensor device. The electrical resistivity is determined over time under predetermined conditions, and a change in the electrical resistivity is monitored over time. A change in fluid visocity may also be determined and monitored over time. The analysing system provides information about an absolute value of a difference of a total base number and a total acid number based on the monitored resistivity change that relates to the quality of the fluid for providing an indication of the remaining useful life of the fluid. In an example, the information about the fluid may correlate to oxidation and/or nitration of the fluid when a change in fluid visocity is below a predetermined threshold.Type: GrantFiled: May 7, 2019Date of Patent: August 17, 2021Assignee: MEAS FRANCE SASInventors: Fabien Gayrard, Francois-Xavier Villemin
