“…Modified Tait Equation. In order to correlate the density data over the entire temperature and pressure ranges accurately, and consequently to obtain a correct evaluation of the derived properties, the density data obtained in this work was correlated with the Tait-type equation, which has been widely used in our previous works 8,10,11…”

The density data for 2-ethylhexyl acetate, 2-methoxyethyl acetate, and diethyl succinate were reported. The density measurements were conducted with a high-pressure vibrating-tube densimeter over 9 isotherms at (283.15 to 363.15) K and 16 isobars at (0.1 to 100) MPa. The uncertainty of each obtained datum was estimated, and the expanded uncertainties of density measurements with a confidence level of 0.95 (k = 2) of density measurement for 2-ethylhexyl acetate, 2-methoxyethyl acetate, and diethyl succinate are 0.1 %. The experimental densities were correlated with the Tait-type equation, and the absolute average percentage deviations were 0.010 %, 0.009 %, and 0.011 % for 2-ethylhexyl acetate, 2-methoxyethyl acetate, and diethyl succinate, respectively. In addition, the isothermal compressibility and the isobaric thermal expansivity were derived from the Tait-type equation.

“…The schematic diagram of the whole measurement system could be found in Ref. [15] and [16]. The measurement system contains a tube densimeter Anton Paar DMA-HPM (Dimensions: 210 mm × 78 mm × 86 mm) with a measuring cell whose volume is about 2 ml where a U-shaped Hastelloy C-276 tube could be excited electronically to vibrate at the characteristic frequencies of liquid LAB at various temperatures and pressures.…”

Densities, isobaric thermal expansion coefficients and isothermal compressibilities of linear alkylbenzene

Abstract. We report the measurements of the densities of linear alkylbenzene at three temperatures over 4 to 23• C with pressures up to 10 MPa. The measurements have been analysed to yield the isobaric thermal expansion coefficients and, so far for the first time, isothermal compressibilities of linear alkylbenzene. Relevance of results for current generation (i.e. Daya Bay) and next generation (i.e. JUNO) large liquid scintillator neutrino detectors are discussed.PACS numbers: 65.20.Jk, 29.40.Mc, 14.60.Pq Densities, isobaric thermal expansion coefficients and isothermal compressibilities of linear alkylbenzene2

“…Properties of pure DME are well documented in the literature; − however, since the idea of using DME in hydrocarbon production is rather new, relevant data in the literature is limited. Chernetsky et al and Ratnakar et al measured density and viscosity of binary systems of DME, brine, and oil as well as partition coefficient of DME between brine and oil.…”

On Oil Recovery Mechanisms and Potential of DME–Brine Injection in the North Sea Chalk Oil Reservoirs

North Sea tight chalk oil reservoirs are well-known for their submicron pore throat sizes and heterogeneous porosity pattern that includes fractures and microfractures. The host rock of these reservoirs is extremely sensitive and can easily react with the injected fluid, which in turn adversely affects the permeability and thus injectivity. The combined effect of these parameters makes oil production in chalk reservoirs extremely difficult. A novel solvent-based enhanced oil recovery (EOR) method that can address these issues is investigated for the first time in the chalk reservoirs. We thouroughly investigate the oil recovery potential and dominant oil recovery mechanisms by dimethyl ether (DME)−brine injection under conditions pertinent to the North Sea tight chalk oil reservoirs. A series of systematically designed high-pressure and high-temperature flooding experiments were carried out using reservoir core and crude oil. The experimental results revealed the strong oil recovery potential of tertiary DME−brine injection with two different DME contents. Furthermore, both secondary and tertiary DME−brine injection scenarios significantly improved the oil recovery with the better performance in the secondary scenario. The results show that the dominant oil recovery mechanism is rapid and strong oil swelling is caused by the preferential partitioning of DME into the oil phase. During DME−brine injection, no indications of rock mineral dissolution and adverse effects on rock permeability were observed. This is one of the advantages of this method over CO 2 , CO 2 −water alternating gas (WAG), and alkaline injections in which the EOR agent causes calcite dissolution, wormhole formation, and scaling issues in fragile chalk reservoirs.
