NO solubility in water and brine up to 60 MPa and 373 K by combining Raman spectroscopy and molecular simulation

“…To calculate solubility from PAR, the experimental PAR data are calibrated on simulation data giving NO solubility as a function of pressure at 295 K, 323 K and 373 K (Figure 3) as there is only a few experimental data available in the literature and only at atmospheric pressure [8][9][10][11][12] . As observed on Raman data, the solubility of NO increases when pressure increases and decreases from 295 K to 373 K. Molecular simulation data of xNO in pure water (Table 2) were interpolated by a polynomial function for each temperature in order to determine NO solubility at any pressure.…”

“…If the thermodynamics of CO2 under the pressure and temperature conditions of a storage (>7.4 MPa and >304.25 K, over the critical point of CO2) is well known, this is not the case for sulphur and nitrogen oxides (SOx and NOx where x stands for the stoichiometric coefficient). As an example, the solubility data for NO are sparse and only atmospheric pressure is documented [8][9][10][11][12] . However the solubility data are essential for the use of the geochemical codes in order to predict the physicalchemical evolution of the storage and the possible chemical reactions occurring between fluids and minerals [3,13] .…”

“…As an example, the solubility data for NO are sparse, and only atmospheric pressure is documented. [8][9][10][11][12] However, the solubility data are essential for the use of the geochemical codes in order to predict the physical-chemical evolution of the storage and the possible chemical reactions occurring between fluids and minerals. [3,13] The high pressure optical cell (HPOC) is an experimental device combining a silica microcapillary, a heating-cooling stage, a pressurization device, and a Raman microspectrometer.…”

Development of a Henry’s constant correlation and solubility measurements of n-pentane, i-pentane, cyclopentane, n-hexane, and toluene in water

“…Furthermore, the solubility data measured in this work are compared with the results of the c-U approach [1,4] extended in this work (table 3) and good agreement between the experimental data and the model predictions is observed. N: calculated minimum of solubility at atmospheric condition (T = 348.95 K); M: data from Winkler [17]; s: data from Fox [128]; Ç: data from Adeney and Becker [155]; d: data from Morrison and Billets [11]; w: data from Klots and Benson [161]. Black curves: model predictions (c-U approach); Grey curve: nitrogen hydrate phase boundary [5,6]; d: experimental data from Chapoy et al [167].…”

Precision Methods for the Determination of the Solubility of Gases in Liquids

“…as a function of the composition at constant T and P. The two curves Inf = lnf(x 3 ; x 2 = 0) and Inf = lnf(x 3 ; x, = 0) characterize the constituent binary solutions [3,1] and [3,2]. constant T and P of the partial molar quantity In(f 3 /x 3 ) as x 3 -» 0, and is thus given by the intercept on the x 3 = 1 axis of the tangent drawn at (x 3 = 0; Xi = 1).…”
