“…Nowadays, SFE is widely employed not only in drugs and food but also in the fields of chemistry, toxicology, environment, petrochemical, textile, and polymers [37] . Notable executions of SFE in different research areas in the last three decades have promoted the extraction of bioactive compounds [38] . Chávez-González, Sepúlveda, Verma, Luna-García, Rodríguez-Durán, Ilina and Aguilar [39] reported that the SFE exhibited a higher extraction yield of flavonoids especially QUR.…”

“…Table 1 lists the important thermophysical properties of CO 2 at the critical point. A review of the thermodynamic and transport properties of supercritical CO 2 can be found in Nikolai et al (Nikolai et al, 2019). Because the thermophysical properties of CO 2 in subcritical and supercritical states differ significantly, the thermodynamic state of a CO 2 power cycle at the pump inlet should be designed accordingly so that it is not too close to the critical point.…”

Improving energy efficiency and reducing carbon emissions are crucial for the technological advancement of power systems. Various carbon dioxide (CO2) power cycles have been proposed for various applications. For high-temperature heat sources, the CO2 power system is more efficient than the ultra-supercritical steam Rankine cycle. As a working fluid, CO2 exhibits environmentally friendly properties. CO2 can be used as an alternative to organic working fluids in small- and medium-sized power systems for low-grade heat sources. In this paper, the main configurations and performance characteristics of CO2 power systems are reviewed. Furthermore, recent system improvements of CO2 power cycles, including supercritical Brayton cycles and transcritical Rankine cycles, are presented. Applications of combined systems and their economic performance are discussed. Finally, the challenges and potential future developments of CO2 power cycles are discussed. CO2 power cycles have their advantages in various applications. As working fluids must exhibit environmentally-friendly properties, CO2 power cycles provide an alternative for power generation, especially for low-grade heat sources.

“…Carbon Dioxide (CO 2 ) and other greenhouse gases (i.e., methane, nitrous oxide, among others) are key contributors to climate change. According to the Energy Information Administration (EIA) estimates, the global emission of CO 2 alone can rise to 6.41 billion tonnes by 2030 [1]. Therefore, various mitigation measures have been proposed to tackle global climate change.…”

The original Shan-Chen’s pseudopotential Lattice Boltzmann Model (LBM) has continuously evolved during the past two decades. However, despite its capability to simulate multiphase flows, the model still faces challenges when applied to multicomponent-multiphase flows in complex geometries with a moderately high-density ratio. Furthermore, classical cubic equations of state usually incorporated into the model cannot accurately predict fluid thermodynamics in the near-critical region. This paper addresses these issues by incorporating a crossover Peng–Robinson equation of state into LBM and further improving the model to consider the density and the critical temperature differences between the CO2 and water during the injection of the CO2 in a water-saturated 2D homogeneous porous medium. The numerical model is first validated by analyzing the supercritical CO2 penetration into a single narrow channel initially filled with H2O, depicting the fundamental role of the driving pressure gradient to overcome the capillary resistance in near one and higher density ratios. Significant differences are observed by extending the model to the injection of CO2 into a 2D homogeneous porous medium when using a flat versus a curved inlet velocity profile.
