“…These assumptions are questionable; for instance, the gas-phase density would change by a factor of 2 in the system studied. In another study, Mohamadi-Baghmolaei et al 104 endeavored to obtain an analytical solution to the species mass balance equation. Here, all variables were fixed except a normalized concentration of the studied species.…”

In this work, the driving force of interfacial mass transfer is modeled as deviation from the gas–liquid equilibrium, which by assumption is thought to exist at the interface separating the gas and liquid phases. The proposed mass transfer model provides a flexible framework where the phase equilibrium description in the driving force can be substituted without difficulties, allowing the mass transfer modeling of distillation, absorption/stripping, extraction, evaporation, and condensation to be based on a thermodynamically consistent phase equilibrium formulation. Phase equilibrium by the Soave–Redlich–Kwong equation of state (SRK-EoS) is in this work compared to the results of the classical Henry’s law approach. The new model formulation can predict mass transfer of the solvent, which Henry’s law cannot. The mass transfer models were evaluated by simulating a single-cell protein process operated in a bubble column bioreactor, and the solubilities computed from the SRK-EoS and Henry’s law were in qualitative agreement, albeit in quantitative disagreement. At the reactor inlet, the solubility of O2 and CH4 was 150% higher with the SRK-EoS than with Henry’s law. Furthermore, the SRK-EoS was computationally more expensive and spent 10% more time than Henry’s law.

The aim of this work was to investigate the application of ferrofluids as a new idea for possibly reducing gas condensate blockage in gas reservoirs. This method was mainly focused on the fabrication of oil-based ferrofluids to control the fluid flow in a porous media to push the fluid out of the media under a magnetic field which can be effective for the reduction of condensate banking in reservoirs. To achieve this goal, magnetic Fe3O4 nanoparticles were modified by polyvinylpyrrolidone (PVP) and oleic acid (OA) and characterized with various analyses. Then, ferrofluids were prepared in kerosene as a base fluid to evaluate the effect of the magnetic field on the flow behavior of the ferrofluids and permeability by a glass micromodel. The characterization of the prepared magnetic nanoparticles proved that the modification of the surface was successfully completed: the magnetic nanoparticles were less than 100 nm in size with an appropriate saturation magnetization (MS) value. The MS values of the magnetic Fe3O4 nanoparticles coated with PVP and OA were 41 and 40 emu.g–1, respectively, while it was 54 emu.g–1 for the uncoated magnetic nanoparticles. Magnetorheological tests showed the fluids induce a yield stress when measured at a low strain rate but behave as a shear thinning liquid at strain rates more than 10 s–1. Glass micromodel tests also depicted that the permeability was increased by applying the magnetic field which highlighted the potential of the oil-based ferrofluids to reduce condensate blockage in gas reservoirs.

“…Accordingly, this imposes a huge burden on the world’s energy supply. Additionally, the environmental concerns and threat of climate change push global economics to shift into a low-carbon energy supply. , A promising alternative for taking the place of conventional fossil fuels (e.g., oil and coal) in producing power and electricity is natural gas, which is known as a clean nonrenewable energy resource. Natural gas generates lower amounts of CO 2 and other contaminants compared to conventional fossil fuels .…”

Acid gas absorption using amine solution is a common method for large-scale acid gas separation, although this separation technique suffers from high energy requirements. In this study, the amine-based acid gas removal (AGR) unit aims for operation enhancement. The new amine mixture, a combination of MDEA-DEA-PZ, is used to remove acid gas components from natural gas. As energy consumption is of high importance for both the industry and community, a systematic exergoeconomic optimization and a sensitivity analysis are performed to avoid production loss and enhance the AGR unit's energy efficiency. An exergy assessment is performed to determine the irreversibility and exergy efficiency of the AGR equipment. The stripper and absorber columns show the largest exergy destruction, that is 8.48 and 7.93 MW, respectively; almost 80% of the entire exergy destruction belongs to the stripper and absorber. The exergoeconomic parameters, such as relative cost difference, exergoeconomic factor, and most importantly, the exergy destruction cost, are determined for the key equipment of the AGR unit. The stripper accounts for the largest exergy destruction cost (0.5260 $/s), followed by the absorber (0.2950 $/s). The Taguchi approach is employed to conduct a proper sensitivity analysis and to determine the optimal operation state with the lowest total exergy destruction cost. Five key parameters, including stripper pressure, lean amine loading, lean amine temperature, lean amine concentration, and PZ concentration, are selected for the optimization phase. It is concluded that the stripper pressure and lean amine loading (with 28 and 25% relative significance, respectively) are the key factors with the largest shares in the total exergy destruction value. The optimal operation state obtained by the Taguchi method shows a remarkable reduction in the exergy destruction cost (19.32%) and steam consumption (23.88%). According to the environmental assessment, CO 2 emissions mitigate from 118.88 to 90.49 t/d while operating the process at the optimal conditions. In addition, the carbon tax is reduced to almost 23% at the optimal condition, and the steam cost declines from 3.77 × 10 6 to 2.87 × 10 6 USD/year. This study further highlights the importance of exergoeconomic assessment as a useful strategy for determining the irreversibility costs in energy and chemical sectors.
