Abstract

This article describes gas hydrates formation, with methane and carbon dioxide as guest compounds, in a small-scale experimental apparatus, appositely designed to reproduce marine offshore reservoirs. The sediment consisted of pure quartz porous sand impregnated with FeSi3 particles, which are produced via gas-atomization and are usually destined to applications in additive manufacturing. Experimental results were compared with the theoretical equilibrium conditions for both types of hydrates. It was established that these particles physically promoted and chemically inhibited the process. The sum of these two opposite effects led to a neutral, or very light promoting activity, on methane hydrates and to a significant inhibition in presence of carbon dioxide
