CO2/impurities cocapture in CCS technology allows reducing the purification costs and avoiding emission of pollutants into atmosphere. The viability transport by pipeline geological storage non-purified flue gas from oxy-fuel combustion biomass other processes, keeping impurities O2 or NO stream along with CO2, is assessed considering thermodynamic hydraulic aspects. For this, we experimentally...

Abstract The SAFT‐γ Mie model is a recent version of statistical associating fluid theory (SAFT), which uses group contribution approach to obtain high‐quality equation state. In this work, is, for the first time, extended ionic liquids (ILs). calculated values agree well with experimental data one‐component, binary and ternary systems that contain ILs, thus indicating versatility accuracy exte...

The vapor-liquid equilibrium of binary mixtures of xenon + SF6 has been measured at nine temperatures from 235.34 to 295.79 K and pressures up to 6.5 MPa. The mixture critical line is found to be continuous between the critical points of the pure components, and hence, the system can be classified as type I phase behavior in the scheme of van Konynenburg and Scott. The excess Gibbs free energie...

Ultrasound imaging systems (UIS) are essential tools in nondestructive testing (NDT). In general, the quality of images depends on two factors: system hardware features and image reconstruction algorithms. This paper presents a new image reconstruction algorithm for ultrasonic NDT. The algorithm reconstructs images from A-scan signals acquired by an ultrasonic imaging system with a monostatic t...

This work describes the development of a new 3D ultrasonic imaging method that combines different beamforming techniques (Phased Array -PAand Synthetic Aperture Focusing Technique -SAFT-). The proposed methodology uses a silicone mask along the x-axis to produce a wide beam in the array width direction (y-axis). Then, a coherent-spatial composition of several phased array B-scan images is imple...

The SAFT-VR equation of state is combined with a semi-continuous thermodynamic approach to model several synthetic and crude oil systems. In our approach, the oil fractions are defined by a continuous distribution that is then represented as discrete pseudo-components using the Gaussian quadrature method. The SAFT-VR parameters for the pseudo-components are obtained from simple linear relations...

Vapor–liquid interfacial tension of square-well ~SW! fluids is calculated using three different methods viz., molecular dynamics ~MD! with collision-based virial evaluation, Monte Carlo with virial computed by volume perturbation, and Binder’s density-distribution method in conjunction with grand-canonical transition-matrix Monte Carlo ~GC-TMMC!. Three values of the SW attractive well range par...

Because of the need of rapid detection of internal defects and embedded object in concrete structures, a ultrasonic detecting method with linear array transducers is presented here, which is the high-resolution and efficient imaging technique for concrete materials by combining with synthetic aperture focusing technique (SAFT). At first, simulation data of array detection are processed to be am...
