The review considers the research and engineering works in selected fields of physical chemistry gas hydrates hydrate technologies, mainly performed over last 10–15 years. Data on structures are given, including formed during phase transitions at low temperatures, new that under ultrahigh pressures. dynamics guest host subsystems is considered brief. Phase diagrams systems involving formation (in particular, some porous media) methods for calculating equilibria compositions these analyzed....
Gas hydrate plugging and corrosion are two major flow assurance problems in oil gas transmission pipelines. Since an incompatibility problem can occur during the simultaneous injection of inhibitors, efficient dual function inhibitors would be advantage. This study reports several newly synthesized waterborne polyurethanes (WPUs) that have a high potential as both kinetic ones. The length side substituents different parts polymer ratio polyethylene glycol (PEG) 400/1,2-butanediol were...
High toxicity and huge foaming are two severe challenges for gas storage strategies based on promoting the hydrate formation using surfactants. The present study used castor oil as an eco-friendly resource to develop novel biosurfactants methane storage. Transmission scanning electron microscopy, dynamic light scattering, interfacial tension measurements revealed surfactant properties of sulfonated (SCO). In addition, a high-pressure autoclave microdifferential calorimeter test unveiled SCO...
In order to systematically study the synergistic effect of gas hydrate inhibition with mixtures methanol (MeOH) and magnesium chloride (MgCl2), impact these compounds on thermodynamic stability methane in systems CH4-MeOH-H2O, CH4-MgCl2-H2O, CH4-MeOH-MgCl2-H2O was experimentally investigated. The pressure temperature conditions three-phase vapor-aqueous solution-gas equilibrium were determined for systems. resulting dataset has 164 points within range 234-289 K 3-13 MPa. All measured as...
Equilibrium conditions of methane hydrate formation in the lumens natural clay nanotubes were analyzed. The water adsorbed by pristine is capable to form confined hydrophilic inner pores 10–100 nm (surface chemistry Al2O3, and external tube's surface SiO2). From 17.5 wt % clay, 12 was involved (conversion ≈ 70%). crystal structure inside nanoconfined spaces halloysite did not change as compared with bulk systems. occurs during cooling at 0–6 °C simultaneously over whole sample, indicating...
The increasing demand in the modern world for energy resources leads to recovery of oil and gas fields remote northern Arctic regions. development additives that effectively prevent complications such as hydrate formation corrosion is a relevant issue. In this work, method modification simple carbohydrates was proposed, which allows one obtain reagents are effective both inhibition (in form synergistic commercial inhibitors) prevention corrosion. Modification glucose sucrose carried out by...
Three-phase equilibrium conditions of vapor–aqueous solution–gas hydrate coexistence for the systems CH4–H2O–organic thermodynamic inhibitor (THI) were experimentally determined. Hydrate measurements with methanol (MeOH), monoethylene glycol (MEG), and diethylene (DEG) conducted. Five concentrations each (maximum content 50 mass%) studied in pressure range 4.9–8.4 MPa. The temperature point complete dissociation methane during constant-rate heating combined vigorous mixing fluids (600 rpm) a...
Nucleation of methane hydrate from water emulsions in five different kinds crude oil and decane have been studied with the use isothermal methods. The experiments were conducted at a temperature –5 °C pressure 12 MPa. It is shown that nucleation rates tend to decrease increase density organic liquid used make emulsion. most likely observed regularities are related rate diffusion surface.
Polymeric models of the core prepared with a Raise3D Pro2 3D printer were employed for methane hydrate formation. Polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), carbon fiber reinforced polyamide-6 (UltraX), thermoplastic polyurethane (PolyFlex), and polycarbonate (ePC) used printing. Each plastic was rescanned using X-ray tomography to identify effective porosity volumes. It revealed that polymer type matters in enhancing All cores except PolyFlex promoted growth (up complete...
