Online Measurement Of Black Powder In Gas And Oil Pipelines

摘要

A method and system for determination of contaminants, such as black powder, in a flowing fluid, such as natural gas, is disclosed. The method comprises transmitting a plurality of light beams over a spectrum of wavelengths through the flowing fluid in a main pipeline and receiving a plurality of measurements relating to transmitted and scattered light beams over the spectrum of wavelengths. The measurements relate to at least one of absorption, reflection or refraction. The received plurality of measurements are compared with a plurality of stored patterns and a result indicative of the determination of the contaminants is output.

1. A method for determination of contaminants in a flowing fluid within a main pipeline comprising:
transmitting a plurality of light beams in a near infrared -spectrum through the flowing fluid; receiving a plurality of measurements relating to transmitted and scattered light beams over the spectrum of wavelengths, the plurality of measurements relating to at least one of absorption, reflection, or refraction of the light beams by the contaminants; comparing the received plurality of measurements with a plurality of stored patterns; and outputting a result indicative of the determination of the contaminants.
