Abstract

In this paper, an electrically small loop loaded with a spiral resonator is proposed for in-situ quality characterization of amine solution in gas sweetening units. The proposed UHF probe resonates at 508 MHz with a miniaturized footprint of 7.2 mm \times7.2 mm. Two different sample holder configurations, i.e. a plastic barrel tube filled with amine solution and direct immersion into the amine solution, are investigated for online quality monitoring of the amine solution. Samples of lean/ amines are collected from different units and tested under laboratory environment. It is found that the proposed sensing system employing UHF probe exhibits strong potential for the online monitoring of amine quality in the regenerative plants.
