Biogas is a renewable energy produced from the anaerobic digestion process. It is mainly
composed by 70% methane (CH 4) and 30% carbon dioxide (CO 2), with minor fraction of …

The aggravation of environmental problems such as water scarcity and air pollution has
called upon the need for a sustainable solution globally. Membrane technology, owing to its …

The increasing challenges in meeting the clean air demand have fuelled growing
environmental awareness to secure effective air purification and separation techniques …

Polymeric membranes have emerged as a competitive technology in gas separation
processes due to their notable energy efficiency, environmentally friendly attributes and …

The development of high-performance thin-film composite (TFC) hollow fiber membranes
coated on top of porous supports is a hot topic both in industry and in science. However, it …

Mixed matrix materials synergistically combining excellent processability from polymers and
unique separation properties from nanofillers have been pursued to achieve superior CO …

In this work, we report on the design, construction and optimization of a pilot scale 3-stage
membrane plant operated by a single compressor for production of high-purity CH 4 and CO …

The development of thin layer on hollow-fiber substrate has drawn great attention in the gas-
separation process. In this work, polydimethysiloxane (PDMS)/polyetherimide (PEI) hollow …

One of the most critical issues encountered by polymeric membranes for the gas separation
process is the trade-off effect between gas permeability and selectivity. The aim of this work …

The CO2 separation from flue gas based on membrane technology has drawn great
attention in the last few decades. In this work, polyetherimide (PEI) hollow fibers were …
