Light scattering for detecting particle formation in fuels

A system for detecting a formation of nanoparticles in a fluid, comprising:

• a temperature controller that provides a set temperature of a source of fluid for a predetermined period of time;
• a monitoring system that performs continuous monitoring of a source of fluid at the set temperature over the predetermined period of time;
• and
• a dynamic light scattering (DLS) measurement system that detects a formation of particles in the source of fluid at the set temperature during the predetermined period of time, wherein the monitoring system detects a cloud point after the particle formation detection by the DLS measurement system.

A system for detecting a formation of nanoparticles in a fluid, comprising:

• a light source that generates a source of light at a fluid sample;
• a temperature controller that provides a temperature of the fluid sample during a temperature ramp cool down operation;
• a forward monitor that monitors an intensity of the source of light to indicate a presence of particles in the fluid sample and measures a cloud point;
• a first photo detector that measures a static light scattering signal when the source of light interacts with the fluid sample;
• a second photo detector that measures a dynamic light scattering signal to determine fluctuations in a scattered intensity when the particles scatter the source of light;
• and
• a measurement system that detects a particle formation in the source of fluid at a wax particle formation temperature, wherein a combination of the first photo detector and the second photo detector detect a presence of the particles before the cloud point is reached.
