Multiphase Flow Control with Embedded System and Color Image Processing

In Oil and Gas Industry, Multiphase Flow of Oil, Gas and Water is present during exploration, transmission, refining process. Finding the content of oil, gas and water is very important for decision making of exploration, transmission and refining process. Using mechanical instruments is not very efficient, as they are bulky, expensive and not very accurate, so using electronic instruments with embedded system and sensors will capture the image of fluid and then converting that image to digital form. Once the image in digital form, we applied image processing technics of de-blurring to increase the accuracy and then calculating the pixels of oil, gas and water to find content profile. Installing these sensors at two points is used to find velocity profile of fluid. We have successfully fabricated multiphase flow metering (MFM) system using local resources. This system is designed to study the application of wire mesh tomography and for capturing image data of multiphase flow of fluids with the help of embedded system and used de-blurring algorithm of image processing, to increase accuracy of content profile and correlation technique was applied to find velocity profile, then with color image processing techniques, content profile of oil, gas and water was calculated to see that calculation of oil, gas and water are the same and verified as it was obtained from the image processing and de-blurring techniques. Results obtained were quite encouraging.
