In recent years, the use of biogas as a natural gas substitute has gained great attention. Typically, in addition to methane (CH4), contains carbon dioxide (CO2), well small amounts impurities, e.g., hydrogen sulfide (H2S), nitrogen (N2), oxygen (O2) and volatile organic compounds (VOCs). One latest trends purification is application membrane processes. However, literature reports are ambiguous regarding specific requirement for pretreatment prior its upgrading using membranes. Therefore, main aim present study was comprehensively examine discuss most achievements single-membrane separation units upgrading. Performing review allowed indicate that, considerable progress been made on polymeric membranes this purpose. For instance, it documented that thin-film composite (TFC) with swollen polyamide (PA) layer ensures successful raw eliminates need pretreatment. The importance performed inference drawn enrichment single step allows obtain upgraded could be employed household uses. Nevertheless, solution may not sufficient obtaining high-purity at high recovery efficiency. Hence, order used applications designed gas, cascade required. Moreover, significant number experimental studies have focused synthetic biogas; meanwhile, data very limited. addition, noted although ceramic demonstrate several advantages, their systems neglected. Summarizing data, can concluded thoroughly evaluate presented issue, long-term pilot-scale practical implications would beneficial supporting development processes

Urgent actions are needed to reduce CO2 emissions and mitigate the increasingly severe impacts of climate change. Since 1990s, membrane research group (MEMFO) at Norwegian University Science Technology has been committed developing effective membranes processes for separation. MEMFO's can be categorized into five main themes: facilitated transport membranes, hybrid carbon contactors, related modeling process simulation. These themes tied industrial applications in capture from flue gas, biogas upgrading, natural gas sweetening, hydrogen purification. Promising identified based on their laboratory-scale performances, have selected onsite testing validate performances as well stability durability. Verified upscaled pilot tests. This account paper summarizes development outcomes over past decade discusses our strategies perspectives future work.

Опубликована: Янв. 4, 2025

In the current years, gas–liquid membrane contactors (GLMCs) have been introduced as a promising, versatile and easy-to-operate technology for mitigating emission of major greenhouse contaminants (i.e., CO2 H2S) to ecosystem. This paper tries computationally study role pores wettability on removal performance inside HFMC. To fulfill this purpose, mathematical model based finite element procedure (FEP) has employed solve momentum mass transport equations in partial-wetting (50% wetting micropores) non-wetting (0% modes during operation. Additionally, comprehensive simulation was ensembled predict results. research, 2-amino-2-methyl-l-propanol (AMP) relatively novel alkanolamine absorbent separate form CO2/N2 mixture. Analysis results implied that micropores significantly deteriorated efficiency due enhancing transfer resistance towards transferring (75% mode > 8% considering 50% micropores).
