“…Use of membrane devices in a process of purification of biological methane from СО 2 is extensively studied nowadays (Atchariyawut, et al, 2007), (Al-Marzouqi, et al, 2008), (Yan, et al, 2007), , (Li, & Chen, 2009), (Mansourizadeh, & Ismail, 2009). Generally those are devices on a basis of hollow fiber membranes, comprising porous polymer fibers.…”

The presented paper describes energy saving technology of biogas purification by microbubling method Description of a new design of microbubling equipment for gas-liquid solution and mathematical simulation of a process during chemisorption of carbon dioxide are presented. Experimental studies of mass transfer characteristics of microbubling equipment, based on model systems, were conducted with an aim to define a possibility of application of microbubling process for removal of carbon dioxide from biogas in order to obtain highly concetrated metane. As a result of the study optimal process parameters are defined, key factors affecting mass transfer characteristics of membrane microbubling method are also established. Efficiency of membrane microbubling equipment from the point of view of interphase mass transfer is assessed.

“…Numerous studies have been performed on CO 2 absorption using membrane contactors in gas-liquid mode of operation. A 2D mathematical model was developed for the physical absorption of CO 2 in hollow-fiber membrane contactors by Al-Marzouqi et al [18]. They studied the effect of operating parameters including different gas and liquid flow rates, gas-to-liquid ratios, and temperatures on the removal of CO 2 .…”

Mathematical Modeling and Simulation of Propylene Absorption Using Membrane Contactors

et al. 2017

Separation of light olefin-paraffin mixtures having the same carbon number is one of the most energy-intensive separation processes in petrochemical industry. Gas-liquid membrane contactors as an alternative to conventional processes have gained increasing interest due to low energy consumption. A 2D comprehensive model was developed to predict the transport and chemical absorption of propylene in a cocurrent microporous membrane contactor. Formations of a complex between propylene and silver ion and dissolution of silver nitrate were considered. With increasing gas flow rate the system efficiency decreases due to the reduction of propylene residence time inside the contactor. As the absorbent amount increases in the tube, both propylene and complex penetrate more deeply into the liquid and a diffusion layer is formed near the gas-liquid interface.

“…The elevation of greenhouse gases gives rise to global warming and environmental issues. Carbon dioxide (CO 2 ) adds up to about 80% of the aforementioned gases [1]. Conventional gas adsorption equipment such as packed, bubble and spray columns and scrubbers suffer from drawbacks like the need for large space, high capital costs and operational problems including liquid channeling, flooding, solvent loss, foaming, etc.…”

“…In contrast membrane contactor technology enjoys the benefits such as, they do not suffer from operational problems; they can be operated over a wide range of flow rates and can be custom designed and modified; also, membrane contactors in form of hollow fiber offer higher surface area 1600-6500 m 2 /m 3 as compared with conventional tray towers or packed columns with 30-330 m 2 /m 3 . Besides, less energy consumption, easy scale up, and independent control of gas and liquid rates are other traits than can characterize them as a capable technology [1,2]. CO 2 removal by membrane contactors has been studied since 1980's and the researchers have investigated factors such as solvent type, membrane material, and modulus type etc.…”

The present paper investigates the simulation of carbon dioxide removal from natural gas stream by a mixture of three amines of diethanolamine (DEA), methyldiethanolamine (MDEA), and 2-amino-2-methyl-1-propanol (AMP) in a hollow fiber membrane contactor made from polypropylene using finite volume method (FVM) IntroductionThe development of industrial activities has increasingly elevated the concentration of greenhouse gases in atmosphere during the past decades. The elevation of greenhouse gases gives rise to global warming and environmental issues. Carbon dioxide (CO 2 ) adds up to about 80% of the aforementioned gases [1]. Conventional gas adsorption equipment such as packed, bubble and spray columns and scrubbers suffer from drawbacks like the need for large space, high capital costs and operational problems including liquid channeling, flooding, solvent loss, foaming, etc. In contrast membrane contactor technology enjoys the benefits such as, they do not suffer from operational problems; they can be operated over a wide range of flow rates and can be custom designed and modified; also, membrane contactors in form of hollow fiber offer higher surface area 1600-6500 m 2 /m 3 as compared with conventional tray towers or packed columns with 30-330 m 2 /m 3 . Besides, less energy consumption, easy scale up, and independent control of gas and liquid rates are other traits than can characterize them as a capable technology [1,2]. CO 2 removal by membrane contactors has been studied since 1980's and the researchers have investigated factors such as solvent type, membrane material, and modulus type etc. to improve its performance. The membrane contactor technology benefits from both separation processes of membrane and adsorption. Qi and Cussler [3,4] first implemented the idea of hollow fiber membrane contactor (HFMC) application for the adsorption of CO 2 using non-wetted polypropylene membrane with porosity of several micrometres and aqueous sodium hydroxide as the adsorbent. Separation of CO 2 by membrane contactors provides more than 70% and 66% reductions in size and weight and up to 10 times adsorption capacity, respectively, compared to the conventional methods [5]. Gas phase flows in one side of HFMC (tube or shell side) and the liquid adsorbent phase flows in the other side while the two streams are not dispersed within each other. In case of hydrophobic membranes (e.g. polypropylene membranes) the gas-liquid interface forms inside the porous volume in the vicinity of the liquid phase (non-wetted operation) [2] and the gas diffuses in the membrane mostly because of concentration
