The self-preservation property of CH4 hydrates is beneficial for the transportation and storage natural gas in form hydrates. Few studies have been conducted on effects chemicals (kinetic thermodynamic promoters) properties hydrates, most available literature limited to pure water. novelty this work that we studied compared kinetics hydrate formation presence amino acids (hydrophobic hydrophili...

One of the main problems in oil recovery via the gas injection is the formation of hydrates in thelines. In order to prevent the formation of hydrate in these lines, which leads to the blockage andsometimes explosion, at first, the equilibrium formation conditions must be determined and then toprevent its formation by changing the thermodynamic conditions or by adding the inhibitors. In thisres...

background: dna damage is one of the major consequences of radiation exposure onto the biological systems. a series of compounds including flavanoids were found to render dna protection against radiation damage. in this study we elucidated the potential of rutin and rutin hydrate to protect plasmid dna against damage induced by irradiation. materials and methods: dpph and hydroxyl radical scave...

in this work the effect of electrolytes on hydrate formation was investigated. to do so, a new model was used in predicting the hydrate formation conditions in presence of both single and mixed electrolyte solutions. the new model is based on the van der waals - platteeuw hydrate equation of state. in order to evaluate the values for the activity of water in electrolyte solutions the simplified...

We investigate the effects of methanol and NaCl, which are known as thermodynamic hydrate inhibitors, on the dissociation kinetics of methane hydrate in aqueous solutions by using molecular dynamics simulations. It is shown that the dissociation rate is not constant but changes with time. The dissociation rate in the initial stage is increased by methanol whereas it is decreased by NaCl. This d...
