In this paper, we present the experimental results obtained from a new flow loop reactor in which methane hydrate particles are crystallized in water droplets transported in a oil flow. The final goal of this apparatus is to couple the rheology with the Particle Size Distribution of water droplets and gas hydrate during crystallization and to observe the influence of dispersants and/or kinetics additives (PVP). In this paper, we describe the flow loop plant and we show preliminary results of the rheology of the emulsion before crystallization and suspension after methane hydrate appearance. The influence of a dispersant additive is observed at a water content of 9 % vol.
