It is estimated that 40% of natural gas reservoirs in the world are contaminated with acid gases (such as hydrogen sulfide and carbon dioxide), which hinder exploitation activities. The demand for will increase by 30% from 2020 to 2050, rise industrial activities lifting travel restrictions. long-term production these high acid-gas fields requires mitigation plans, include capture, utilization,...

This work focused on the CO2 capture by absorption into amines based absorbents. Aqueous mixtures containing different types of amines (MEA, MDEA, AMP, PZ and PZEA) are experimentally compared in a special gas-liquid contactor (a cables-bundle contactor) with respect to the CO2 removal performances at 25°C and atmospheric pressure. This absorption process was also simulated with the use of publ...

A microporous polypropylene (PP) hollow fiber membrane contactor was used as a reactor to biodegrade phenol in high-salinity solutions by Pseudomonas putida CCRC14365 at 30C. Suspended cells grew only at a NaCl concentration below 2.5 wt%. On the other hand, cells within hollow fibers completely degraded 0.5 g/L of phenol in solution containing NaCl up to 8.6 wt%, likely due to the fact that th...

Isolation of carboxylic acids from dilute aqueous effluents can be achieved by the combination liquid-phase catalyzed reaction with liquid-liquid extraction. Exemplarily heterogeneously esterification acetic acid methanol, accelerated a cation-exchange resin and simultaneous transfer product methyl acetate into solvent ShellSol T, was successfully performed in Taylor-Couette disc contactor (TCD...

In this study, a newly developed nitrogen (N) and phosphorus (P) recovery process using membrane contactor termed NPHarvest was tested with different liquid waste streams in large-scale trials. Ammonia captured ammonium sulfate form hydrophobic membrane, while precipitated as sludge alkali precipitation coagulation processes. The were selected to cover the potential for included two mesophilic ...

When a human rubs a contactor that is vibrating laterally at 3–10 Hz with an amplitude of ~1 mm, the friction is perceived as being greater than that sensed when touching a stationary contactor. This phenomenon could be exploited for a new vibrotactile approach to friction perception; however, the principles behind it have yet to be explained. In this study, we hypothesized that the perceived f...

This research includes both experimental and CFD investigation in the hydrodynamic behavior of a new type of column tray introduced as “Concap” tray. The proposed column tray is used in contactor columns especially in stripping columns. The hydrodynamics of this Concap tray is investigated in a 1.2m in diameter column. Using air-water system, the experiments were performed for different liquid ...
