摘要：

A near-infrared (near-IR)/fiber optics method for determining the cloud point of waxy crude oils has been developed. This technique is based on near-IR absorbance changes resulting from wax crystallization during cooling of waxy crude samples. The method shows good repeatability and is supported by viscosity and differential scanning calorimetry measurements. The experimental apparatus allows cloud point measurements at the elevated temperatures (to 135-degrees-C) and pressures (to 14 000 kPa) which can be encountered during production and transportation of crude oils.
