Densities and derived thermophysical properties of the 0.9505 CO2+ 0.0495 H2S mixture from 273 K to 353 K and pressures up to 41 MPa

Review of flowmeters for carbon dioxide transport in CCS applications

“…Different CO 2 capture processes produce different levels of impurities (Table ). Typically, the concentration of CO 2 will be between 90% and 99%, which may seem very pure; however, phase behavior and physical properties of highly CO 2 rich fluids are affected by impurities . Fig.…”

“…Unreliable density predictions will therefore lead to measurement error. Uncertainties around the EoS for mixtures of CO 2 with impurities have been discussed for classical cubic equations of states, for example Peng‐Robison (PR‐EoS) and Soave‐Redlich‐Kwong (SRK‐EoS), as well as multi‐parameter EoS, GERG ,, . In general, the accuracy of these equations in the vicinity of two‐phase region would be expected to be weak.…”

“…Typically, the concentration of CO 2 will be between 90% and 99%, [37][38][39] which may seem very pure; however, phase behavior and physical properties of highly CO 2 rich fluids are affected by impurities. [40][41][42][43][44][45][46] Fig. 2 shows the variation of density of carbon dioxide / nitrogen mixture (95 mol% CO 2 + 5 mol% N 2 ) as function of pressure at a variety of temperatures using GERG EoS 47,48 by REFPROP v8.0.…”

Experimental and modelling study of the densities of the hydrogen sulphide + methane mixtures at 253, 273 and 293 K and pressures up to 30 MPa

“…A full description of the experimental set-up and procedures are available in Bouchot and Richon [14], Coquelet et al [15] and Nazeri et al [16]. The density of the studied mixture have been measured in a Hastelloy Vibrating Tube Densitometer (VTD), Anton Paar model DMA 512, using the one fluid reference calibration method [17].…”

“…In this work, the PR, SAFT-VR Mie and GERG-2008 [13] EoSs were employed to predict the densities of mixtures and were implemented into the thermodynamic package HWPVT [16] [26] [27] [28] [29].…”
