Fiber-Optic Sensor For The Quality Of Oil And Petroleum Products

Abstract

The technical characteristics and performance of the equipment depend on the quality of petroleum products. Optical refractometric methods for determining the composition of oil based on refractive indices have become widespread. The main disadvantage of the known methods of analysis is the long measurement time associated with the need to take a sample from the pipeline. The aim of the work is to develop a fiber-optic sensor of increased reliability for rapid analysis of the quality of oil and petroleum products in difficult operating conditions. A constructive and technological solution of a fiber-optic sensor for the quality of petroleum products of increased reliability has been developed on the basis of a developed two-channel fiber-optic converter with a cylindrical hollow tube with a liquid, the refractive index of which is determined. The developed design and technological solution of a fiber-optic sensor, which performs instantaneous measurement of the refractive index of a liquid in a pipeline, will increase the reliability of the sampling system of oil pipelines, reduce unreasonable costs of the sampling process, and increase the accuracy of measuring the quality of liquid transparent to visible and infrared radiation of petroleum products.
