Natural Gas Flaring—Alternative Solutions

Gas flaring is one of the major problems in the world. It consumes useful natural resources and produces harmful wastes, which have negative impacts on society. It is one of the most tedious energy and environmental problems facing the world today. It is a multi-billion dollar waste, a local environmentalcatastrophe and environmental problem which has persisted for decades. From the year 1996-2010, in Nigeria, 12,602,480.25 million ft 3 of natural gas was flared (NNPC). This is equivalent to ...

Gas Hydrate—Properties, Formation and Benefits

There are numerous gas hydrate reserves all over the world, especially in permafrost regions and ocean environments. The abundance of gas hydrate reserves is estimated to be more than twice of the combined carbon of coal, conventional gas, and petroleum reserves. These hydrate deposits hold a significant amount of energy which can make hydrate a sustainable energy resource. The comprehensive research on the properties and formation of methane hydrates is paramount to ensure efficient and effe...

A Generalized Correlation for Predicting Ethane, Propane, and Isobutane Hydrates Equilibrium Data in Pure Water and Aqueous Salt Solutions

Hydrate formation can cause serious problems in hydrocarbon exploration, production, and transportation, especially in deepwater environments. Hydrate-related problems affect the integrity of the deepwater platforms, leads to equipment blockages, and also increases operational costs. In order to solve these problems, salts are used as thermodynamic inhibitors and also mixed with the drilling fluids in most drilling processes. A comprehensive understanding of hydrate formation in aqueous salt ...

Methane Hydrate Dissociation Conditions in High-Concentration NaCl/KCl/CaCl 2 Aqueous Solution: Experiment and Correlation

The dissociation conditions of methane hydrate in high concentration aqueous solutions of NaCl, KCl, and CaCl2 are reported in this work. A total of 80 sets of H−L−V equilibrium data of methane hydrate in aqueous solutions of NaCl (9.45−23.71 wt %), KCl (13.93−21.88 wt %), and CaCl2 (13.78−35.50 wt %) were measured at the temperature range of (273.65−291.85) K and the pressure range of (5.43−65.12) MPa. A modified step-heating method with high efficiency was employed in the meas...
