Emission of sulfur dioxide (SO2) from coal power plants has to be controlled and minimized to reduce environmental risk. This study aimed to investigate the hollow fiber composite membrane was used for the removal of SO2 from a SO2/CO2/N2 mixed gas. Moreover, for the improvement of SO2 removal efficiency, the polyetherimide (PEI) membrane was coated with poly(vinyl chloride)‐graft‐poly(oxyethylene methacrylate) (PVC‐g‐POEM). The PVC‐g‐POEM/PEI composite hollow fiber membrane was extensively characterized by various techniques including scanning electron microscopy, Fourier transform infrared spectroscopy, and atomic force microscopy. Experiments with permeation of SO2, CO2, N2, and a ternary gas mixture were carried out to observe membrane behavior in response to different operating conditions. As a result, permeance of SO2 was 105–2705 GPU and selectivity of SO2/CO2 was 3.9–175.6. From the mixed gas separation experiment, the maximum SO2 removal efficiency reached up to 84.5%. © 2014 American Institute of Chemical Engineers AIChE J, 60: 2298–2306, 2014

Immobilization is one of the most effective and powerful tools used in industry, which has been studied and improved since the last century. Various immobilization techniques and support materials have been used on both laboratory and industrial scale. Each immobilization technique is applicable for a specific production mostly depending on the cost and sensibility of process. Compared to free biocatalyst systems, immobilization techniques often offer better stability, increased activity and selectivity, higher resistance, improved separation and purification, reuse of enzymes, and consequently more efficient process. Recently, many reviews have been published about immobilization systems; however, most of them have focused on a specific application or not emphasized in details. This review focuses on most commonly used techniques in industry with many recent applications including using bioreactor systems for industrial production. It is also aimed to emphasize the advantages and disadvantages of the immobilization techniques and how these systems improve process productivity compared to non-immobilized systems.

“…It turns out that the permeation was quasi-constant with a pressure increase. This behaviour can be explained by the transport mechanism through the ionic liquid, which is described by solution-diffusion mass transport processes when the maximum driving force is directly related to the CO 2 solubility in the ionic liquid [32][33][34][35][36][37][38][39][40] …”

This work reports the interaction study of two supported ionic liquid membranes (SILMs) based on 1-butyl-3-methylimidazolium hexafluorophosphate ([C 4 mim][PF 6 ]) and 1-butyl-3-methylimidazolium tetrafluoroborate ([C 4 mim][BF 4 ]), which were impregnated into porous zirconia supports with 20 nm average pore diameters. The interaction of ionic liquid-support observed from diffuse reflectance (DR), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy and energy dispersive spectroscopy (SEM/EDS) is reported. The IR spectrum in the 600 to 4000 cm −1 range showed a specific interaction of the ionic liquid with the support. The N 2 and CO 2 permeances in the SILMs with [C 4 mim][BF 4 ] were 8.7 × 10 −8 mol·s −1 ·m −2 ·Pa −1 and 9.6 × 10 −7 mol·s −1 ·m −2 ·Pa −1 , respectively. The separation factor through the ionic liquid in the membrane as a function of temperature showed that the SILMs studied here can be used for CO 2 separation at low temperatures.
