“…In the typical operating conditions (about 200 atm and 2-6°C), ice-like solids trap methane molecules forming the so-called clathrate hydrates [87]. Such hydrates can aggregate and lead to the clogging and rupture of the pipeline, with an obvious drastic ecological and economical aftermath [88].…”

a b s t r a c tThe present work aims at reviewing our current understanding of fractal structures in the frame of colloid aggregation as well as the possibility they offer to produce novel structured materials. In particular, the existing techniques to measure and compute the fractal dimension d f are critically discussed based on the cases of organic/inorganic particles and proteins. Then the aggregation conditions affecting d f are thoroughly analyzed, pointing out the most recent literature findings and the limitations of our current understanding. Finally, the importance of the fractal dimension in applications is discussed along with possible directions for the production of new structured materials.

“…El poder inhibidor de un aditivo evaluado en el sistema a alta presión, se define a partir de la capacidad de dicho aditivo de desplazar la curva de estabilidad de los hidratos, hacia condiciones de formación más severas, es decir, disminución de la temperatura o incremento de la presión [2]. A partir de los datos experimentales se construyen diagramas presión-temperatura, que permiten identificar las distintas etapas del proceso de formación y disociación de hidratos [4].…”

“…En este sentido se hace necesario desarrollar nuevas tecnologías y técnicas de control, basadas en la mitigación de los efectos negativos ocasionados por los hidratos [1]. Las técnicas empleadas para la prevención o inhibición de los hidratos consisten en: aislamiento térmico del sistema, calentamiento de líneas y equipos y uso productos químicos denominados inhibidores; siendo esta última técnica la más utilizada en la industria del gas natural y en la explotación de petróleo [2].…”

Resumen-En este trabajo se realizó un estudio experimental de los procesos de formación y disociación de hidratos en sistemas a presión atmosférica y a alta presión. Se evaluó el potencial de compuestos naturales (provenientes de fuentes no comestibles), como inhibidores para prevenir problemas de aseguramiento de flujo por la formación de hidratos en operaciones de producción y procesamiento de gas natural. En las pruebas a presión atmosférica se empleó tetrahidrofurano (THF) como molécula huésped. Se diseñó y ensambló un equipo a alta presión para evaluar el comportamiento de los hidratos de gas a altas presiones y bajas temperaturas, empleando dióxido de carbono (CO2) y metano (CH4).Palabras Claves-Alta presión, inhibidores, hidratos, compuestos naturales, presión atmosférica.Abstract-In this work, processes of hydrate formation and dissociation at atmospheric pressure and high pressure conditions were experimentally studied. The potential of some natural compounds (from non-edible sources) was evaluated as thermodynamic inhibitors to prevent flow assurance problems due to hydrates formation in natural gas production and processing operations. In atmospheric pressure tests, tetrahydrofuran (THF) was used as guest molecules. A high pressure equipment was designed and commissioned to evaluate the behavior of gas hydrates at high pressure and low temperatures, using carbon dioxide (CO2) and methane (CH4).

AbstractFossil fuels are still a necessary and important part of modern living, keeping cars running and houses heated for example. As demands have risen and reservoirs of oil and natural gas have depleted, it has become increasingly more important to tap in to fields that were once classified as undesirable. Sour fields, fields high in acidic gases such as hydrogen sulfide and carbon dioxide, are one such option. There are many difficulties and dangers associated with working sour fields, such as toxicity of the sour gases, hydrate formation and corrosion of equipment that have prevented these resources being used in the past. Many varied methods of overcoming these problems have been developed, from removing the sour components to inhibiting their effects. This review highlights the major issues raised by sour fields as well as a wide range of solutions in use today.
