“…In an industrial scale, a stirred tank is of other limitations to its application, such as the difficulty in its seal when pressure is high and the higher energy consumption. In a stirred tank, the viscosity of hydrate slurry increases rapidly with the increase of volume fraction of hydrate (Fidel-Dufour et al, 2006), the power needed to maintain the turbulence of the reactant system increases fast as well. The gas hydrate volume percent might be limited to lower than 5% (Vysniauskas and Bishnoi, 1983) in an industry process for the high viscosity of hydrate slurry.…”

“…[101,131,191,192,193] Most of the time these studies have been conducted using anti-agglomerants in hydrate slurry observing the phase change from water to hydrates, which results in the formation of the suspension. Variables such as concentration, particle size distribution, particle density, and from a flow assurance point of view, apparent viscosity are considered in such analysis.…”

Gas hydrates attracted intense research interest when it was first recognised some 70 years ago that they were responsible for the blockage of flow lines, valves and well heads, thereby causing great loss of production and other severe safety hazards to the oil and gas industry. After many decades, these compounds are still the topic of research activities in various multi-disciplinary fields, including chemical and petroleum engineering, earth and geophysics, chemistry and environmental sciences. This is not only due to the great impact that these compounds have on the oil and gas industry, but also to the potential applications they have in many evolving areas, including, but not only, natural gas storage and transportation, carbon dioxide sequestration, and sea-water desalination. It is generally accepted that gas hydrates represent the largest source of hydrocarbons on earth, something which has not been appreciated until only recently.Management, either prevention or application or both, of gas hydrates requires a complete knowledge and understanding of the formation, decomposition and inhibition mechanisms of gas hydrates, which in turn demands advanced experimental methods and instrumental techniques for gas hydrate characterisation. This paper reviews a broad range of techniques that have been used for natural gas hydrate characterisation. It includes the basic physical science principles of each method and the gas hydrate properties that each method is capable of detecting, including some modern instrumental analyses that enable direct determination of gas hydrate phases and possible measurement of molecular interactions within the fluid phases. 

“…Regarding the prediction of the hydrate slurry viscosity two different approaches have been reported in the literature. The first one can be referred to as a contact-induced agglomeration model [14][15][16]. In this model, the crystallisation-agglomeration process is described as the result of a contact mechanism between a water droplet and a hydrate particle.…”

Résumé -Discussion sur les mécanismes d'agglomération entre particules d'hydrate dans les émulsions eau dans huile -Le bouchage des conduites lors de la formation des hydrates de gaz dans les émulsions eau dans huile peut être appréhendé par l'augmentation de la fraction volumique effective de la suspension de particules d'hydrate. Cette augmentation est due à un processus d'agglomération qui se produit pendant la phase de formation des hydrates. Deux mécanismes d'agglomération présentés dans la littérature sont discutés. Le premier est le mécanisme d'agglomération induit par contact pour lequel le processus de cristallisationagglomération est le résultat du contact entre une goutte d'eau et une particule d'hydrate. Le second est le mécanisme d'agglomération limité par le cisaillement pour lequel la compétition entre force hydrodynamique et force adhésive est considérée. Il est proposé de réunir ces deux mécanismes dans un modèle unifié afin de prédire l'évolution de la viscosité de la suspension d'hydrate pendant la formation. Un tel modèle repose sur un modèle de bilan de population dans lequel le noyau d'agglomération est associé au mécanisme d'agglomération induit par contact et le noyau de fragmentation est associé au mécanisme d'agglomération limité par le cisaillement.
