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,...

Membrane Condenser (MC) is a novel membrane contactor operation recently investigated for the valorization of industrial waste gaseous streams. In particular, until now, it was applied for water recovery from flue gas, cooling tower plumes, etc. More recently, its effectiveness and flexibility in contaminants (such as, NH3 , HF, SO2 ) removal and control from waste gaseous streams was also prov...

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...

This work aims to intensify trans-p-coumaric acid (p-CA) heterologous production. p-CA exhibits antimicrobial properties, low hydrosolubility, and retro-inhibition activity, making its production limited due accumulation in the broth. To overcome these limitations, an in-stream product recovery process (ISPR) is proposed consists a liquid-liquid extraction assisted by hollow fiber membrane cont...

This study evaluated the efficacy of a supercritical carbon dioxide (SCCO(2)) system with a gas-liquid porous metal contactor for eliminating Escherichia coli K12 in apple cider. Pasteurized, preservative-free apple cider was inoculated with E. coli K12 and processed using the SCCO(2) system at CO(2) concentrations of 0-10% (wt.%, g CO(2)/100g product), outlet temperatures of 34, 38, and 42 deg...

The membrane contactor system is one of the most important technologies to trap CO2 from natural gas. To apply this technology, hollow fibre membranes with a superhydrophobic surface must be used, where were prepared kaolin clay through phase inversion/sintering technique and modified by three types fluoroalkylsilane (FAS) molecules (C6, C8, C10) at different immersion times (6, 24, 48,72 h) ca...

Introduction: Removal of ammonia from water of a waste water treatment plant by a membrane contactor were simulated on transient state and compared with experimental data. This technology will be applied in the hydrogen and oxygen production by electrolysis via renewable energies as can be seen in Figure 1. The aim of this study relies on fulfill the process requirements in the electrolysis, si...
