In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...

Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations of the model are solved via the finite...

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...

Laterally asymmetric vibrotactile stimuli produce anisotropic or direction-dependent friction force that function as a friction display system [1]. In this study, we showed that laterally symmetric vibrotactile stimuli increase friction perception by a similar principle. We measured the frictional forces between a sliding finger pad and a contactor laterally vibrating at 3 or 5 H. We found that...

This paper presents a method of simple and multiple water fuel emulsions preparation in a liquid-liquid contactor with Couette-Taylor flow (CTF contactor). This method concerns the integration of the CTF contactor with diesel engines for the injection of just-prepared emulsions. Stable simple O/W and multiple O/W/O emulsions, both with quite narrow drop size distribution, have been prepared. Th...

In this study, hydrogen was recovered and purified by using a membrane contactor unit from CO2-rich gas without the use of any basic chemicals such as amines. The operational parameters were adjusted to achieve high CO2 removal H2 recovery. effects flow rate, pressure, composition (CO2/H2 ratio), pressure difference between liquid gas, gas/liquid ratio on recovery investigated. Depending contac...

Abstract This paper presents a predictive mathematical model of high-pressure membrane contactor, with view to developing plant-wide natural gas sweetening including amine regeneration. We build upon an existing contactor by Quek et al. [Chem Eng Res Des 132:1005–1019, 2018], which uses combination 1-d and 2-d mass-balance equations predict the CO2 absorption flux wetting under lean solvent ope...
