Carbon membranes for oxygen enriched air – Part I: Synthesis, performance and preventive regeneration
Haider, Shamim; Lindbråthen, Arne; Lie, Jon Arvid; Hagg, May-Britt (Journal article; Peer reviewed, 2018)Chemisorption of oxygen on the active sites of carbon layers limits the use of carbon membranes in air separation application. A novel online electrical regeneration method was applied to prevent the active sites on carbon ... -
Carbon membranes for oxygen enriched air – Part II: Techno-economic analysis
Haider, Shamim; Lindbråthen, Arne; Lie, Jon Arvid; Hagg, May-Britt (Journal article; Peer reviewed, 2018)Carbon membrane (CM) separation process for producing oxygen-enriched air (OEA) at a concentration of 50–78 mol% O2 in a single stage process with no recycle stream has been investigated. This paper (Part II of a two-part ... -
CO2 separation with carbon membranes in high pressure and elevated temperature applications
Haider, Shamim; Lindbråthen, Arne; Lie, Jon Arvid; Andersen, Ingerid Caroline Tvenning; Hagg, May-Britt (Journal article; Peer reviewed, 2017)Carbon hollow fibers (CHF) were fabricated by carbonization of deacetylated cellulose acetate precursor. To enhance membrane permeation properties, pore structure was tailored by means of an oxidation and reduction process ... -
Pilot–Scale Production of Carbon Hollow Fiber Membranes from Regenerated Cellulose Precursor-Part II: Carbonization Procedure
Haider, Shamim; Lie, Jon Arvid; Lindbråthen, Arne; Hagg, May-Britt (Journal article; Peer reviewed, 2018)The simultaneous carbonization of thousands of fibers in a horizontal furnace may result in fused fibers if carbonization residuals (tars) are not removed fast enough. The optimized purge gas flow rate and a small degree ... -
Regenerated cellulose based carbon membranes for CO2 separation; Durability and aging under miscellaneous environments
Haider, Shamim; Lindbråthen, Arne; Lie, Jon Arvid; Hagg, May-Britt (Journal article; Peer reviewed, 2018)Predictive models regarding the aging effect on membrane separation properties are required to estimate the membrane life time with acceptable permeability and selectivity for the respective application. The current article ... -
Vehicle fuel from biogas with carbon membranes; a comparison between simulation predictions and actual field demonstration
Haider, Shamim; Lindbråthen, Arne; Lie, Jon Arvid; Carstensen, Petter Vattekar; Johannessen, Thorbjørn; Hagg, May-Britt (Journal article; Peer reviewed, 2018)The energy contents of biogas could be significantly enhanced by upgrading it to vehicle fuel quality. A pilot-scale separation plant based on carbon hollow fiber membranes for upgrading biogas to vehicle fuel quality was ...
