Abstract

Solid contaminants have been found to be a major obstacle in assuring the quality of flow in pipelines. The presence of these substances leads to clogging of pipes that causes serious issues downstream when transporting oil or gas. This paper suggests an Electrical Capacitance Tomography (ECT) system for real-time measurement of solid contaminants in gas pipelines. It consists of a ring of eight electrodes evenly distributed in the circular cross section of the probe. The speed-up enhancement is achieved using a Field Programmable Gate Array (FPGA) for the post-processing part of the system to accelerate the intensive matrix multiplications which are required in the image reconstruction algorithm. Experimental results on field-collected solid contaminants demonstrate the capability of the system to build in real-time two dimensional cross section images of the contaminants while giving an estimated measurement of their concentration.
