A comprehensive model for simulation and optimization of industrial-scale splitting towers that is able to predict the yield hydrolysis bio-based triglyceride feedstocks presented in this work. This includes a variable glycerol equilibrium ratio, which function composition temperature calculated using polar version perturbed chain statistical association fluid theory (PC-SAFT), autocatalytic ef...

The SAFT-VR equation of state is extended to treat heteronuclear chain fluids, focusing, in particular, on symmetric and asymmetric diblock chains. The chain molecules studied are composed of segments of different size and/or energy of interaction. Both symmetric and asymmetric systems are considered. The theoretical predictions are compared with isothermal– isobaric and Gibbs ensemble Monte Ca...

Synthetic aperture focusing technique (SAFT) has been used in non-destructive testing mainly in its simplest form that mimics acoustic lenses used for focusing ultrasonic beams at a point of a solid object or structure. This paper presents a review of SAFT algorithms applied for post-processing of ultrasonic data acquired in non-destructive inspection of metals. The performance of SAFT in terms...

The statistical associating fluid theory for potentials of variable range plus dipole (SAFT-VR+D) is extended to study associating dipolar fluids. In the SAFT-VR+D approach dipolar interactions are taken into account through the use of the generalized mean spherical approximation to describe a reference fluid of dipolar square-well segments. This enables the effect of the dipolar interactions o...

Hydrogen is a promising alternative to carbon based energy carriers and may be stored in large quantities subsurface storage deposits. This work assesses the impact of static (density phase equilibria) dynamic (viscosity diffusion coefficients) properties on pressure field during injection extraction hydrogen porous subsurface. In first step, we derive transport for water, their mixture using P...

Experience from the ultrasonic inspection of nuclear power plants has shown that large focused transducers are relatively effective in suppressing material structure noise. Operation of a large focused transducer can be thought of as integration (coherent summation) of individual beams reflected from the flaw and received by individual points at the transducer surface. Synthetic aperture focusi...

The Special Affine Fourier Transform or the SAFT generalizes a number of well known unitary transformations as well as signal processing and optics related mathematical operations. Unlike the Fourier transform, the SAFT does not work well with the standard convolution operation. Recently, Q. Xiang and K. Y. Qin introduced a new convolution operation that is more suitable for the SAFT and by whi...

Equations of state should be tuned to reservoir conditions by PVT tests for phase behavior modeling. This tuning is achievable via an optimization method. In this work, simulated annealing algorithm is applied as a global optimization method to parameter optimization for PC-SAFT from the statistical associating fluid theory incorporating hard chain as reference fluid. The optimization parameter...
