Systems and methods for varnish detection

Abstract

Embodiments herein relate to systems and methods for varnish detection and/or monitoring in hydrocarbon fluids. In various embodiments, a system for monitoring varnish compounds in fluids is included herein including a control circuit in communication with a fluid property sensor. The system can measure one or more fluid properties (such as dielectric constant, density, resistivity, viscosity and the like) with the fluid property sensor, monitor the same over a time period, and identify an occurrence of a rate of change in the measured property indicating a presence of the varnish compounds. In various embodiments, a system herein can be configured to measure a fluid property of a fluid with a fluid property sensor, monitor the fluid property value over a time period, and predict a time of the onset of varnish compound formation based on the trend of the fluid property value over time. Other embodiments are also included herein.
