Investigation of the influence of polyelectrolytes hydrodynamic properties on the hydrate formation process

One of the most perspective non-traditional sources of
hydrocarbon raw materials and energy is gas hydrates (GH), which
stimulates their large-scale study in many laboratories and scientific
centers around the world. The interest in the GH is related to the possibility
of their industrial application. The use of technologies for storage and
transportation of natural gas in the form of GH requires fundamental
kinetic studies of the hydration process at atmospheric pressure in the
presence of chemical impurities (catalysts, surfactants, etc.). During the
research, an increase in the rate of gas hydrates formation was discovered
at the expense of activated impurities and composite compounds obtained
on their basis, which lead to changes in the hydrochemical and
hydrodynamical modes of systems. It was established that the process of
GH formation occurs due to the binding of methane macromolecules and
other chemical impurities, which contribute to increase the number of
moles of gaseous methane, due to the flow of exchange processes between
the polymer matrix and water soluble salts, as well as a result of the change
in the hydrodynamics of the water system. The purpose of this work is to
investigate the effect of polyelectrolytes solutions hydrodynamic properties
on the GH formation. We used a number of ionenes based on polymeric
quaternary ammonium salts, side aliphatic radicals of different lengths
contained in the acyl fragment.
