Abstract

The hydrate formation during the transportation and injection of carbon dioxide in pipelines always leads to the risk of plugging. The development of a cost-efficient CO2 sequestration method requires efficient hydrate inhibitors. In this research work, the synthesized carbon quantum dots (CQDs) of monoethylene glycol (MEG) were tested with CO2 hydrates for their hydrate inhibition efficiency. The hydrothermal method was used for the synthesis of CQDs. The synthesized CQDs were characterized using UV light (365 nm), UV-vis absorption, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and photoluminescence (PL) spectroscopy. MEG CQDs were found to have very good water solubility and fluorescence properties. The MEG CQDs were tested for their CO2 hydrate inhibition efficiency using the sapphire rocking cell unit. Test results proved that MEG CQDs are much more effective as a CO2 hydrate inhibitor in comparison to MEG.
