phase composition and Saturated Liquid properties in binary and ternary systems containing carbon dioxide n decane and n tetradecane
The Journal of Chemical Thermodynamics, 2013Co-Authors: Mohammad Kariznovi, Hossein Nourozieh, Jalal AbediAbstract:Abstract Experimental phase equilibrium data have been measured for the binary and ternary systems containing (carbon dioxide, n-decane, and n-tetradecane) at 323.2 K over the pressure range (1 to 6) MPa using a designed PVT apparatus. The measurements presented in this paper were undertaken to determine Liquid phase composition and Liquid Saturated properties (density and viscosity) when a Liquid hydrocarbon (n-decane, n-tetradecane, and their mixtures) was Saturated with carbon dioxide. The generated data for compositions and densities were correlated with the Soave–Redlich–Kwong (SRK) and Peng–Robinson (PR) equations of state (EOS). The adjustment of binary interaction parameters and volume translation technique has been employed to correlate the experimental compositions and densities. The adjusted binary parameters from the data of binary pairs (carbon dioxide + n-decane) and (carbon dioxide + n-tetradecane) were used to correlate the generated ternary data. The calculated ternary compositions were found to be in good agreement with the experimental data using the binary parameters from the data of binary pairs for both EOSs. The results for the density of Saturated Liquid phase indicated that the volume translation should be applied to all components in the binary and ternary systems to describe accurately the Saturated Liquid densities for mixtures.

Fluid Phase Equilibria, 2013Co-Authors: Hossein Nourozieh, Mohammad Kariznovi, Jalal AbediAbstract:Abstract The solubilities of carbon dioxide (CO2) in decane, tetradecane and their binary mixtures have been measured at a temperature of 373.2 K and pressures up to 6 MPa using a rocking mechanism pressure–volume–temperature apparatus. The measurements presented in this paper were undertaken to determine the solubility and Liquid Saturated properties (density and viscosity) when a Liquid hydrocarbon (decane, tetradecane and their mixtures) was Saturated with CO2. The generated data for compositions and densities were correlated with the Soave–Redlich–Kwong and Peng–Robinson equations of state (EOSs). The binary interaction parameters were adjusted, and the volume translation technique was employed to correlate the experimental compositions and densities. The generated ternary data were correlated with the adjusted binary parameters from the data of binary pairs (CO2 + decane) and (CO2 + tetradecane). The calculated ternary compositions were found to be in good agreement with the experimental data using the binary parameters from the data of binary pairs for both EOSs. The results for the density of the Saturated Liquid phase indicated that volume translation should be applied to all components in the binary and ternary systems to accurately describe the Saturated Liquid densities for mixtures.

experimental measurement and equation of state modeling of Liquid Saturated properties solubility density and viscosity of ethane n octadecane binary systems
Journal of Chemical & Engineering Data, 2012Co-Authors: Hossein Nourozieh, Mohammad Kariznovi, Jalal AbediAbstract:The Liquid Saturated properties (solubility, density, and viscosity) data for binary system of ethane + n-octadecane at three temperatures (323, 373, and 423) K and pressures up to 8 MPa were measured using a designed pressure–volume–temperature (PVT) apparatus. The experimental data (Saturated Liquid phase composition and density) were compared with the modeling results obtained using the Peng–Robinson and Soave–Redlich–Kwong equations of state. Both models were capable of representing the solubility data well; however, the Peng–Robinson equation of state gave better estimation of Liquid Saturated densities both with and without volume translation.

Journal of Chemical & Engineering Data, 2016Co-Authors: Katsuyuki Tanaka, Ryo Akasaka, Eiichi Sakaue, Junichi Ishikawa, Konstantinos KontomarisAbstract:In this work, comprehensive measurements of pρT (pressure–density–temperature) properties of cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336mzz(Z)) were performed. Although this novel fluid has been proposed for various applications, including its use as a possible working fluid for organic Rankine cycle systems, reliable experimental data on its thermodynamic properties are scarcely available. In this work, the isochoric method was employed to obtain the properties of this fluid along 26 isochores for densities between 88 and 1295 kg·m–3, and 344 pρT data points were obtained in the temperature range from 323 K (49.85 °C) to 503 K (229.85 °C) and at pressures up to 10 MPa. The data covered single-phase Liquid and vapor regions, two-phase region, and supercritical region. The data in the critical region were correlated with a simple polynomial expression, which was used to determine the critical parameters analytically. The vapor pressures and the densities of the Saturated Liquid and vapor were obtained fr...

The Journal of Chemical Thermodynamics, 2018Co-Authors: Qua Zhong, Ju She, Xueqiang Dong, Yanxing Zhao, Haiyang Zhang, Hao Yu-guo, Maoqiong GongAbstract:Abstract In this paper, bubble point pressures and Saturated Liquid densities of {2,3,3,3-Tetrafluoroprop-1-ene (R1234yf) + propane (R290)} binary mixtures were measured using a compact single-sinker densimeter. Measurements were carried out over temperatures from (255.048 to 300.135) K and mole fractions of R1234yf at (0.113, 0.217, 0.322, 0.422, 0.533, 0.625). The experimental standard uncertainties were estimated to be less than 5 mK for the temperature, 2 kPa for the pressure, 0.003 for the mole fraction and 0.02% for the density. The experimental bubble point pressures were correlated by the Peng-Robinson equation of state, while the experimental Saturated Liquid densities were represented with the VDNS and our modified Rackett equations. In addition, Saturated Liquid densities of azeotropy point at temperatures T = (253.150, 263.150, 273.150, 283.150 and 293.150) K were determined based on our previous and present work.

Saturated Liquid density equation for pure refrigerants including cfcs hcfcs hfcs hcs hfos hfes pfas and iss based on the scaling law and the law of rectilinear diameter
International Journal of Refrigeration-revue Internationale Du Froid, 2017Co-Authors: Haiyang Zhang, Xueqiang Dong, Yanxing Zhao, Maoqiong Gong, Quan Zhong, Bo Gao, Yanyan Chen, Ercang LuoAbstract:Abstract This work aims to develop a simple Saturated Liquid density equation (SLDE) with good modeling, extrapolation and prediction capabilities for pure refrigerants based on the well-known scaling law and law of rectilinear diameter. Saturated Liquid densities, critical temperatures and critical densities of 53 refrigerants from 8 different categories including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), hydrocarbons (HCs), hydrofluoroolefins (HFOs), hydrofluoroethers (HFEs), perfluoroalkanes (PFAs) and inorganic substances (ISs) have been studied using the proposed SLDE. The equation exhibits a good modeling behavior with a total mean absolute relative deviation (MARD) of 0.105%, and presents reasonable extrapolation accuracy, especially the extrapolations from medium temperature range to low and high temperature ranges, with total MARDs of 0.286% and 0.467%, respectively. The three parameters in the equation were generalized for different categories to better predict Saturated Liquid densities. The generalized equation shows a more competitive prediction performance than the commonly used generalized SLDEs, with a total MARD of 0.783%. Furthermore, critical temperatures and critical densities were simultaneously predicted using the generalized equation with total MARDs less than 0.743% and 0.998%, respectively.

experimental study on the Saturated Liquid density and bubble point pressure for r1234ze e r290
Journal of Chemical & Engineering Data, 2016Co-Authors: Haiyang Zhang, Xueqiang Dong, Qua Zhong, Maoqiong Gong, Ju SheAbstract:Saturated Liquid densities and bubble point pressures of trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) + propane (R290) binary mixture were measured at temperatures from (253.141 to 293.284) K and mole fractions of R1234ze(E) from (0.1746 to 0.8803) using a compact single-sinker densimeter. The standard uncertainties were estimated to be less than 5 mK for temperature, 600 Pa for pressure, 0.003 for mole fraction, and 0.01% for density. The experimental Saturated Liquid densities were reproduced by the VDNS and our modified Rackett density equations, while the experimental bubble point pressures were represented with the Patel–Teja (PT) equation of state. Good agreement between values of calculation and experiment were found for both Saturated Liquid densities and bubble point pressures. In addition, Saturated vapor and Liquid densities of azeotropy point at temperatures T = (258.150, 263.150, 273.150 and 283.150) K were determined.

vapor pressures and Saturated Liquid densities of hfo1234ze e at temperatures from 253 343 to 293 318 k
International Journal of Refrigeration-revue Internationale Du Froid, 2016Co-Authors: Maoqiong Gong, Xueqiang Dong, Haiyang Zhang, Quan Zhong, Jun ShenAbstract:Abstract Vapor pressures and Saturated Liquid densities of HFO1234ze(E) (trans-1,3,3,3-tetrafluoropropene) were measured at temperatures from 253.343 to 293.318 K by a compact single-sinker densimeter. The accuracy of the densimeter was verified by the experimental performance of HC290 (propane) at temperatures from 253.432 to 293.312 K. The standard uncertainties of HFO1234ze(E) in temperature, pressure and density were estimated to be less than 5 mK, 1 kPa and 0.01%, respectively. Comparisons were made between the present vapor pressures and other experimental data available in the open literature, and good agreement was found, while the Saturated Liquid densities were reproduced by five equations of state in Wagner-type or Rackett-type, and good agreement was found among them. Finally, two recommended equations for Saturated Liquid densities of HFO1234ze(E) were obtained with a valid temperature range from 251.450 to 382.504 K.
