Abstract

Natural gas and hydrogen are fuels that are forecast to shape the future energy landscape. This thesis presents three novel sensors designed to characterise their phase behaviour, to tackle current and future operational challenges that pose risks to production reliability and throughput. While the application of each sensor is unique, they are all based on microwave resonators as the measurement platform. This exploits the inherent accuracy of frequency measurements in conjunction with the robustness of high-pressure cavity resonators and advantage of real-time signal processing. Four techniques are demonstrated addressing phase characterisation, impurity freezeout, solid deposition, and hydrogen isomer composition.
