PP-III-62CATALYTIC INTENSIFICATION OF NATURAL GAS HYDRATES FORMATIONAsadov M.M., Alieva S.A.Institute of Chemical Problems National Academy of Sciences of Azerbaijan, AzerbaijanE-mail: asadov_salim.mail.ruChemical-technology approaches allowing catalytic intensification of the preventionprocesses of gas hydrates formation at motion of gas-liquid stream of natural gas in systemnatural gas well – gas wire have been worked up. Technological regimes of treatment of gasstream have been determined.The features of continuous influence of inhibitory factors on process of gas flow at lowtemperatures and relatively high pressure differences ΔP have been studied by using oftechnological installation modulating the system natural gas well – gas wire.The dependences of gas quantity flowing from installation on ΔP at low temperatureshave been studied with consideration of real states of process of gas – liquid phase flowing.Obtained experimental data for non-inhibitory and inhibitory processes have been comparedunder the same conditions.It was established that when intensification of prevention process of gas hydratesformation is high, at the same thermodynamic conditions due to continuous treatment of gasby methanol and polyvinyl alcohol, which are absorbed into the bentonite, by glycigol,absorbed into the silica gel, and by calcium chloride.Vibration conjugate process of gas hydrates formation and break-up taking place in gasliquidsystem with using of membrane electrode of electrochemical cell has been found.Periodic vibrations of membrane potential have been found at treatment of natural gas bymethanol at low temperatures. Periodic character of vibration effect is determined byconjugate variations of equilibrium concentrations of components gas hydrates formation andbreak – up.Dependence of potential value on time of gas stream current across gas pipeline is givenin temperature interval 262 –293 K and at pressures from 0.15 to 0.5 MPa.585
