Thermodynamic fundamentals of extraction of hydrocarbons from oil sludge with the use of supercritical propane-butane mixture

摘要: Current paper represents the results of study on phase equilibrium characteristics and thermal conductivity some thermodynamic systems involved in extraction hydrocarbons from oil sludge with use propane-butane mixture both liquid supercritical (SC) states. Phase equilibria have been studied for such previously unexplored binary as: "naphthalene – propane/butane", "sulfur "water propane/butane". The studies carried out traditional version static method, as well by using an optical cell studies, designed high pressures. Thermal water-oil emulsion at a pressure 0.098 MPa temperature range 290 360 K has investigated hot-wire method.
