“…In biogas or natural gas there are components present which may be detrimental to the membrane, such as H 2 S, higher hydrocarbons (HHC) or other impurities. Only two references were found on this for natural gas [145,146].…”

CO 2 emission from anthropogenic sources has raised global environmental concerns, and efficient reduction of these greenhouse gas emissions by capturing CO 2 is recognized world-wide as very important along with the implementation of new green energy technology. Membrane technology is considered to be one of the efficient techniques to be used for CO 2 capture. Among different types of membranes, mixed matrix membranes and facilitated transport membranes have gained much interest in recent years due to documented high CO 2 permeance through these membranes, especially when the gas is humid as is the case for flue gas from combustion. In the current review, a comprehensive discussion is focused on the development of hybrid membranes involving the selection of the fixed site carrier (FSC) membranes and the interaction of nanosilica-particles in a polymer membrane for efficient CO 2 capture. Other facilitated transport membranes and mixed matrix membranes are also briefly discussed.

“…A few studies have been conducted on this issue where the researchers are studying the long-term performance of a polymeric PVAm/PVA membrane when exposed to H 2 S, MEG, TEG and higher hydrocarbons (HHC) which are usually present in natural gas. Their membranes seemed to tolerate the impurities relatively well, but were vulnerable to HHC [86,87]. …”

Membrane separation systems require no or very little chemicals compared to standard unit operations. They are also easy to scale up, energy efficient, and already widely used in various gas and liquid separation processes. Different types of membranes such as common polymers, microporous organic polymers, fixed-site-carrier membranes, mixed matrix membranes, carbon membranes as well as inorganic membranes have been investigated for CO2 capture/removal and other energy processes in the last two decades. The aim of this work is to review the membrane systems applied in different energy processes, such as post-combustion, pre-combustion, oxyfuel combustion, natural gas sweetening, biogas upgrading, hydrogen production, volatile organic compounds (VOC) recovery and pressure retarded osmosis for power generation. Although different membranes could probably be used in a specific separation process, choosing a suitable membrane material will mainly depend on the membrane permeance and selectivity, process conditions (e.g., operating pressure, temperature) and the impurities in a gas stream (such as SO2, NOx, H2S, etc.). Moreover, process design and the challenges relevant to a membrane system are also being discussed to illustrate the membrane process feasibility for a specific application based on process simulation and economic cost estimation.

“…Moreover, Natural gas reservoirs are predominantly comprised of methane gas as well as CO 2 , H 2 S, N 2 , water and heavy hydrocarbons. Separation of all these impurities, especially CO 2 is extremely important to meet the pipe line specifications (Washimuddin and Hägg, 2012). To separate or capture CO 2 gas, several processes such as membrane gas separation, cryogenic distillation, amine absorption, membrane gas absorption and adsorption processes have been developed (Sabouni et al, 2014).…”
