Abstract
The study of hydrate formation has increasingly attracted the world of science as a matter of immediate application and of high importance, mainly in the oil and gas industries. Understanding the kinetics of hydrate formation and its dissociation is very important. The formation of gas hydrate can cause blockage of ducts in oil unit production and transportation with subsequent loss of production and possible safety problems. Traditionally, the prevention of hydrate-plug formation has been done with thermodynamic inhibitors, however, economic and environmental factors allied to technical problems associated with thermodynamic inhibitors have motivated research and new development to identify technological alternatives such as kinetic inhibitors. Among the kinetic inhibitors polysaccharides such as pectin are potential candidates. The present work aims to study the effect of pectin as a biological kinetic inhibitor on the nucleation of gas hydrates. The experimental runs were carried out on a high pressure cell and the pectin performance was compared with the well-known inhibitor ethanol. The pectin showed superior inhibition effect under temperature range of 2 to 6°C, demonstrating potential for using as biological hydrate inhibitor.
